Abstract

Ethnopharmacological relevance: The family Arecaceae is one of the largest plant families in the world. It is widely distributed in tropical regions (Brazil, Saudi Arabia, Middle Eastern countries and Egypt, Indonesia, Malaysia, and Thailand). Traditionally, plants of this family were used to treat various disorders, like gastrointestinal ailments, diabetes, spasms, sexual dysfunction, nephritis, rheumatism, cough, diarrhea, and hypertension. Aim of the review: This review highlights the biological properties, phytochemistry, and chemotaxonomic classification of the phytochemicals of different species of the family Arecaceae. Materials and methods: The relevant information on the family Arecaceae was collected from scientific databases (Google Scholar, ScienceDirect, ACS Publications, PubMed, Wiley Online Library). Information was also collected from online databases and books. theses. The literature cited in this review dates from 2001 to June 2022. Result: About 141 compounds have been isolated from different species of the family Arecaceae, including flavonoids, fatty acids, terpenoids, fatty acid esters, sugars, fatty alcohols, vitamins, carotenoids, tannins, ceramide derivatives, glyceryl derivatives, stilbenoid derivatives, simple phenolic glycosides, sterols, alkaloids, lignans, amino acids, and phenolic compounds. Their structure and presence in each species of this family are presented in tabular form. In biological studies, the crude extracts and metabolites of the medicinally important species of the family Arecaceae have different biological activities, including, antioxidant, antimicrobial, analgesic, renal protective, antiparasitic, cardioprotective, antidiabetic, anti-mutagenic, antiinflammatory, anticancer, diuretic, hepatoprotective, antihyperlipidemic, antipalatelet, antiviral, antipyretic, antifungal, antidiarrheal, antitrichomonal, antiacetylcholinestrase, and antihypertensive. This review examines folkloric uses, phytochemistry, and biological activities of selected members of this family.

INTRODUCTION

Herbal remedies, which have been employed in both traditional and modern systems since ancient times, are the earliest medical supplies that are known to exist. The WHO stated that herbal medicines are defined as herbs, herbal preparations, herbal finished products and herbal ingredients [1]. Around 80% of the world's population relies on herbal medicine for their primary healthcare requirements [2]. Patients favor herbal remedies over traditional ones due to a persistent illness and dread of surgery, severe morbidity, rising medical expenses and the drawbacks of innovative drugs [3].

Using plant components in their purest form, either fresh or dried, is a common practice in traditional medicine for treating and preventing a wide range of illnesses [4]. Alkaloids, flavonoids, phenolics, terpenoids and glycosides are some of the major types of therapeutic phytochemicals synthesized by plants [5]. Medicinal plants are used to find and develop new therapeutic medications [6].

The Arecaceae, also known as the Palm family (palmeae), is one of the most well-known plant families [7] (Figure 2). This family belongs to the monocot order Arecales of flowering plants [8]. It has 181 genera and 2600 species and it is one of the largest families in the world. Bush species, woody trees or even grasses are examples of the physical and functional diversity among this family's species. It is primarily found in tropical regions [9]. Species of this family are mostly present in Indonesia, Malaysia and Thailand [9-11].

According to previous phytochemical studies, this family contains anthocyanidins, lignans, benzenoids, benzoquinone, monoterpenoids and nor isoprenoids [12], fatty derivatives, sterols, phenolic acids and their derivatives, flavonoids and other classes [8].

Plants in this family have biological activities like hepatoprotective, anti-hyperlipidemic, anti-diabetic, anti-oxidant, anti-parasitic, antihypertensive, renal protective, cardioprotective, anti-microbial (antibacterial, antifungal and antiviral), anti-pyretic, anti-inflammatory, anti-mutagenic, anti-platelet, analgesic, anti-ulcer, neuropharmacological, anti-acetylcholinesterase, anti-Alzheimer [8] and anti-cancer activities [13].

 

Traditional Uses

The plants in this family are mostly used for medicinal purposes. According to a review of traditional medical practises, Chamaerops humilis is used as stipe or leaf extract for the treatment of gastrointestinal ailments, diabetes, spasms and digestive issues [14]. Regular use of Phoenix species has been traditionally used to treat sexual dysfunction, nephritis, rheumatism, burning feelings and cough [15]. Diarrhea is treated with a C. nucifera husk fibre extract in Brazil [16].

Herbal tea made from Hyphae thebaica is historically thought to be effective in treating hypertension [17]. Hypertension is treated with a decoction of the leaves of the Acrocomia aculeata plant [18].

The Colocasia gigantea tuber is used to alleviate drowsiness as well as to lessen "internal heat" (fever) [13].

 

Phyto-Constituents

Phytochemicals are biologically active, naturally occurring chemical substances that are present in plants and which enhance human health. Phytochemicals are plant compounds that shield plant cells from environmental dangers such dehydration, stress, UV exposure, pathogenic attack and pollution. Phytochemicals build up in a variety of plant tissues, including the roots, stems, leaves, flowers, fruits and seeds [19]. Tannins, anthraquinones, alkaloids, terpenoids, cardiac glycosides, steroids, flavonoids, phlobatannins, saponins and reducing sugars are the major phytochemical components found in therapeutic plants [20].

Compounds 1-142 were isolated from medicinally important genra of Arecaceae (Table 1). Commonly, phenolic compounds are the major constituents of this family. Many fatty acids, fatty alcohols, fatty acid esters, sterols, vitamins, carotenoids, tocopherols, phenolic compounds, amino acid, terpenoids, tannins, sugars, stilbenoid derivatives, glyceryl derivatives, alkaloids, lignan derivatives, ceramide derivatives and simple phenolic glycosides are reported in this family.

This mentioned data revealed the chemotaxonomic classification of phytochemicals present in different genra of the family Arecaceae.

 

Biological Properties

The family Arecaceae has medicinal importance due to the presence of secondary metabolites such as glycosides, terpenoids, alkaloids, sterols, tannins, flavonoids, carotenoids and phenolic compounds. The biological activities of various species of the family Arecaceae are highlighted below in Table 2.

 

Antimicrobial Activity

In Vitro as well as In Vivo studies have shown that the leaf extract of Elaeis guineensis exhibits excellent antimicrobial activity, effective against both bacterial and fungal infections, especially against the yeast Candida albicans [49]. M. flexuosa induce susceptibility to conventional antibiotics in Gram-positive, Gram-negative and Candida species [24]. The most efficient extract against bacteria was methanolic extract of A. catechu (18Escherichia coli growth was prevented by a leaf extract from C. nucifera [52]. With minimal inhibitory concentrations ranging from 190 to 3120 g/mL, the extract of Syagrus coronata exhibited bactericidal activity [53].

The PKnB kinase enzyme is inhibited by extract of onecapaus bataua but bacterial growth is unaffected. It has an IC50 of 60.9 g/mL [54]. Staphylococcus aureus' growth was entirely prevented by the extract of Attalea speciosa at its highest dose (500 mg/mL) [55]. Gram-positive and Gram-negative bacteria were moderately sensitive to the aqueous methanol extract and ethyl acetate fraction of D. leptocheilos leaves [56].

When 30 µL of aqueous fruit extract of Borassus flabellifer was used, a 23mm-diameter zone of inhibition was seen against S. aureus [57]. Both S. aureus and E. coli were moderately susceptible to the mild bactericidal effects of aqueous fractions of C. mitis [58]. E. coli growth was slowed down by a S. edulis extract. At 100% concentration, the maximum inhibition zone was found (average diameter 18.783 mm) [59]. Bacillus subtillus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans were all susceptible to the antibacterial effects of aqueous methanol extract of Hyophorbe verschaffeltii [60].

The PKnB kinase enzyme is inhibited by Euterpe precatoria but bacterial growth is unaffected. It has an IC50 of 77.4 g/mL [54]. When mixed with chloramphenicol, kanamycin, streptomycin, erythromycin and tetracycline, Raphia hookeri extract was able to reduce the antibiotic concentration by up to 50% [61]. Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa are all susceptible to the antibacterial effects of oil of Chamaerops humilis [55]. Strong antibacterial activity was demonstrated by the ethanolic extract of H. thebaica fruits against Salmonella typhi and Staphylococcus aureus [62]. Antibiotic-resistant bacteria strains were able to be inhibited and killed by the oil from Syagrus coronate [63]. Staphylococcus aureus, Escherichia coli, Pseudomonas aerigunosa and Bacillus cereus were all susceptible to methanolic extracts of leaves of Phoenix dactylifera. Gram-positive bacteria showed to be more susceptible than gram-negative bacteria [64].

 

Anti-Parasitic Activity

Hamsters infected with L. braziliensis were examined for response to ethyl acetate extract of Cocos nucifera. After 14 days, skin lesions in infected hamsters were reduced by the ethanolic extract of Cocos nucifera (300 mg/kg, 0.2 mL) [35].

 

Hepatoprotective Activity

It has been demonstrated that the aqueous dates extract has hepatoprotective properties [65]. It has been demonstrated that methanol extract of leaves of Elaeis guineensis works well as a hepatoprotectant [65]. According to this study, an aqueous flesh extract of Phoenix dactylifera can reduce the CCl4-induced hepatotoxicity [11]. Aqueous extract of Areca catechu provided significantly more protection against liver injury in rats at 2000 mg/kg (67-85%) compared to 500 and 1000 mg/kg (18-33%) [66]. D-galactosamine-induced histological alterations in liver were significantly inhibited by an ethanolic extract of Dypsis lutescens. The extract enhanced liver operations [67]. Both as an aphrodisiac and a cure for male impotence, date palm pollen can be used to manage sexual dysfunction [65].

 

Antioxidant Activity

The serum increases of the liver function markers ALT and AST caused by CCl4 were greatly reduced and returned to normal (p<0.001 and p<0.05, respectively) following treatment with H. verschaffeltii leaf extract [32]. High radical scavenging activity is present in the hydro-alcoholic pulp extract of B. guineensis against DPPH [68]. Strong antioxidant activity was demonstrated by the D. leptocheilos aqueous methanol extract and ethyl acetate fraction, with SC50 values of 12.8±0.56 µg/mL and 17±0.77 µg/mL, respectively [56]. The leaf hydro-ethanolic extract of Caryota urens has a significant antioxidant activity (21.25±4.51 mg/g) [57].

The antioxidant activity of extract of Borassus flabellifer was assessed every five minutes for the next thirty minutes. Thus, the DPPH percentage of radical scavenging was (56.69, 62.20, 62.99, 64.57, 66.14, 66.93 and 67.72%), correspondingly [57]. Ethyl acetate and butanol fractions of Rhapis excels demonstrated outstanding antioxidant activity in DPPH scavenging activity (86.2 and 75.6%, respectively) [69]. 107.6, 126.7, 172.7 and 196.3 g/mL were the IC50 values, respectively, for the Methanol/Ultrasonic (MU), Methanol/Water bath (MW), Ethanol/Ultrasonic (EU) and Ethanol/Water bath (EW) extracts of Hyphaene thebaica [62].

Fruit of L. australis can help prevent oxidative damage to physiologically active compounds and lipid peroxidation [39]. For DPPH radical scavenging, the IC50 values of methanolic extracts of endocarp and mesocarp of Calamus erectus are 0.10 and 0.12 mg/mL, respectively. When the concentration was raised, the antioxidant tests of both extracts improved [70]. When compared to aqueous extract (IC50 = 25 g/mL), methanolic extract of Dypsis lutescens had the highest level of radical scavenging activity (IC50 = 18 g/mL) [13]. At 100.0 μg/mL, all extracts of Euterpe precatoria demonstrated significant radical scavenging activity [71]. The inhibition rates of oxidation using 0.4 mL of extracts from the pulp and kernel cake of S. romanzoffiana were 97.00, 0.43% and 95.13 0.7%, respectively [72].

E. guineensis leaf methanol extract shows strong hepatoprotective effects against paracetamol-induced liver injury in mice [73]. Dictyosperma album leaves have much higher antioxidant activity than Archinto-phoenix alexandrae leaves, with values of 243.51 and 129.40 g AECE/g (IC50 = 60 and 108.5 g/mL, respectively) [12]. Phoenix dactylifera has been shown to have antioxidant and anti-mutagenic effects [11]. The ethyl acetate fraction of Sabal palmetto demonstrated strong free radical scavenging, reducing, hydrogen peroxide, nitric oxide and lipid peroxidation inhibition abilities [74]. In comparison to its pulp, aqueous, methanolic and ethanolic extracts of peel of tucum-do-cerrado showed increased antioxidant activity [75].

 

Analgesic Activity

When compared to a control group, the ethanolic extract of Cocos nucifera significantly reduced writhing by 24, 34 and 52.4% at doses of 50, 100 and 150 mg/kg, respectively [16]. At doses of 200, 400 and 600 mg/kg, p.o., of extract of Phoenix loureiroi, the percentage inhibition of writhes is 33.34, 57.04 and 66.62%, respectively [15]. At a dosage of 400 mg/kg, all the tested samples had variable substantial analgesic efficacy. The percentage of inhibition was higher in the entire ethanolic extract and EtOAc fraction of Caryota mitis than in the other samples (96.1 and 92.85%, respectively) [76].

In a hot plate test, oral administration of extract of Phoenix sylvestris at dosages of 300 and 450 mg/kg at 120 min (6.60±0.28 and 8.88±0.55) significantly lengthened the latency period to thermal stimuli [77]. In a formalin-induced test, methanolic extract (500 mg/kg) of Calamus rotang resulted in 68.47% inhibition while indomethacin provided 70.72% inhibition [78]. For dosages of 50, 100, 200 and 400 mg/kg, b.wt., respectively, the leaf extract of Areca catechu showed greater antinociceptive action (55.8, 57.7, 86.5 and 88.5%) than the stem extract (30.8, 36.6, 40.9 and 59.6%) [79]. The amount of writhing caused by acetic acid decreased significantly at dosages of 150 and 300 mg/kg of ethanolic extract of Borassus flabellifer (30.67±2.84 and 19.33±1.56, respectively) [80].

 

Renal Protective Activity

In a Wistar rat model, treatment with 10% coconut water lowered crystal formation in renal tissue and decreased the amount of crystals in urine. Additionally, the extract protected the kidneys from oxidative stress buildup and renal function decline [81]. Aqueous extract of date flesh effectively reduced the increases in plasma creatinine and urea brought on by GM nephrotoxicity and mitigated proximal tubular damage [82].

 

Cardioprotective Activity

Cardiovascular markers (CK-MB and troponin-T) are decreased in the serum at doses of 50, 100 or 200 mg/ 100 g of Cocos nucifer [83].

 

Anti-Hyperlipidemic Activity

L. australis ether extract reduced blood cholesterol and triglycerides by 50 and 43.6%, respectively [39].

 

Anti-Hypertensive Activity

In Vivo experiments using methanolic extract (PSLME) and hydro-alcoholic extract of Phoenix sylvestris (PSLHAE) show antihypertensive and anti-diabetic effects without producing toxicity [84]. At a dosage of 25 mg/kg, extract of Cocos nucifera significantly reduced mean systolic blood pressure (from 185.3±4.7 to 145.6±6.1 mm Hg) in the deoxycorticosterone acetate salt-induced hypertension model [16].

 

Anti-Platelet Activity

Adenosine diphosphate (ADP) and Ca+2 ionophore-induced aggregation were most effectively inhibited by A. catechu [85].

 

Anti-Trichomonal Activity

C. nucifera husk fibre crude methanol extract showed significant antitrichomonal action (IC50 value of 5.8 mg/mL) and activity was lower than that of metronidazole [16].

 

Effects on Bone Structure

Administration of virgin coconut oil significantly raised bone volume, avoided a decline in trabecular number and decreased trabecular separation [16].

 

Anti-Diabetic Activity

According to this investigation, the methanolic extract of Phoenix sylvestris inhibited both enzymes to varying degrees (26.45-78.48% for α-amylase and 38.28-76.07% for α-glucosidase) [86]. At 400 g/mL, ethanolic and methanolic extracts of Phoenix roebelenii showed the strongest inhibitory efficacy. The maximum inhibitory effect for both α-amylase (75.5±0.66%) and α-glucosidase (77.5±1.07%) was displayed by the ethanolic extract, whereas the activity of the methanolic extract was 70.4±0.62% for α-amylase and 75.5±0.09% for α-glucosidase [87]. The extract of Phoenix dactylifera reduced the levels of creatinine (0.95±0.1, 0.92±0.5 and 0.86±0.4 mg/dL), urea (52.33±0.1, 45.9±1.4 and 36.54±1.3 mg/dL) and alkaline phosphatase (212.39±3.2, 191.11±1.9 and 182.91±2.3 mg/dL), respectively, in the blood at doses of 150, 300 and 600 mg/kg [88].

The percentage of α-amylase enzyme inhibition was 8.42±0.97% for concentrated C. urens flour up to 5 mg/mL, compared to 10.77±2.64% for cooked flour [89]. Methanolic extracts of endocarp and mesocarp of Calamus erectus showed concentration-dependent inhibition of α-glucosidase (IC50 = 1.69 and 2.00 mg/mL) and α-amylase (IC50 = 2.74 and 3.30 mg/mL), respectively [70]. A 0.2 g/kg oral dose of the extract of Raphia gentiliana decreased blood sugar levels [90].

 

Anti-Cancer Activity

Although the components of dates have demonstrated an anticancer effect, their precise mode of action in the prevention of tumours is unknown [11]. Methanolic extracts of A. catechu have anticancer effects on breast cancer and oral squamous carcinoma cell lines (HSC-2) [13]. Isovitexin, a component of Dypsis lutescens, has anti-cancer properties [91]. Salacca fruit extract was cytotoxic to vero cells and a normal human fibroblast cell line [59].

The methanol extract of Elaeis guineensis significantly damaged MCF-7 cells in a dose-dependent manner [50]. Colorectal cancer Her2/CT26 cell proliferation was suppressed by trans-scirpusin A compound of Borassus flabellifer [92]. M. argun seeds were recommended for patients with human colon cancer risk factors and as an adjuvant therapy to cancer chemotherapy because they had chemopreventive effects against hepatocarcinogenesis [93].

 

Anti-Mutagenic Activity

Phoenix dactylifera fruit extract was found to have strong anti-mutagenic properties [11].

 

Diuretic Activity

At a dosage of 200 mg/kg, ethanol extract of Borassus flabellifer has significantly raised the urine levels of Na+, K+ and Cl [94].

 

Anti-Diarrheal Activity

Phoenix dactylifera aqueous extract can be used to treat diarrhoea by lowering the mean number of faeces compared to the saline control group [11].

 

Anti-Viral Activity

Extracts of Phoenix dactylifera exhibit a potent capacity to reduce infectivity of Pseudomonas phage ATCC 14209-B1 [95].

 

Anti-Fungal Activity

Phoenix dactylifera possesses antifungal qualities in both its leaves and its pits [11]. At a dosage of 100 g/mL, methanol extract of leaf of Borassus flabellifer demonstrated antifungal activity against a number of different fungal species, including Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Candida albicans and Candida blanki [96].

 

Anti-Pyretic Activity

The ethanol extract of Phoenix loureiroi significantly reduced pyrexia in a dose-dependent manner [15]. Significant antipyretic efficacy was shown by n-hexane and aqueous fractions of Caryota mitis against yeast-induced hyperthermia [76]. Hyperthermia was significantly reversed by a Borassus flabellifer extract [80].

 

Delivery and Labor Relaxation Activity

Date fruit components have a substantial impact on pain relief and relaxation during labour [11].

 

Male Infertility and Testicular Dysfunction Activity

Phoenix dactylifera pollens can raise testosterone levels in cirrhotic patients, improving their sexual well-being [11].

 

Female Infertilitily and Harmone Levels Activity

The herb Phoenix dactylifera can also be used to treat female infertility brought on by hormonal imbalance [11].

 

Anti-Acetylcholinesterase (AChE) Activity

In Vitro spectrophotometric analysis was used to determine the anti-AChE activity. The enzyme was nearly completely inhibited by the extract of Areca catechu (90.1±0.4), demonstrating its high AChE inhibitory action [85].

 

Anti-Inflammatory Activity

C. nucifera root extracts reduced activities of 15-LOX (IC50 = 24.57±1.16 and IC50 = 8.31±0.73), sPLA2 (not determind (nd) and 24.68±0.08), COX-1 (nd) and 27.21±1.66) and COX-2 (nd and 39.41±1.36), respectively [97]. The microencapsulated oil from Acrocomia aculeata fruits also presented anti-inflammatory effects in paw edema and pleural edema models, both induced by carrageenan [18]. Methanolic extract of Ravenea rivularis at a dose of 125 g/mL showed an anti-inflammatory effect (66% inhibition) in comparison with dexamethasone at a dose of 50 ng/mL (65% inhibition) [32]. Aqueous extract of Areca catechu inhibited 5-LOX with an IC50 of 25.07 [13]. Mice's intestinal inflammation could be decreased by P. loureiroi extract when given orally at a dose of 5 mg/kg [98]. In Vivo tests on paw edoema and ear erythema brought on by croton oil revealed anti-inflammatory efficacy in oil derived from Euterpe oleracea fruits. 1226.8 mg/kg was the typical effective dose [99].

The activity of butyrylcholinesterase was reduced by B. odorata extract, suggesting that it may have anti-inflammatory effects [100]. At 800 µg, a root extract from Borassus flabellifer reduced hemolysis and denaturation by 50% [101]. Ethanolic extract of Dypsis lutescens shows the ability to inhibit the pro-inflammatory enzymes hyaluronic acid (37.78±1.26 and 29.79±1.27) and  matrix metallopeptidase (814.51±20.25 and 629.18± 18.64), respectively, at two doses (250 and 500 mg/kg, p.o.) [67]. Anti-inflammatory potential of Caryota mitis, its extract was able to attenuate the inflammatory response in mice paw edema induced by carrageenan at a concentration of 400 mg/kg [102]. The methanolic extract (500 mg/kg) of Hyophorbe verschaffeltii demonstrated continuous and significant suppression of edoema by 48.54 and 44.2% at 8th and 12th h, respectively, demonstrating longer-lasting anti-inflammatory efficacy than diclofenac sodium (100 mg/kg) [60] (Figure 3).
