Acrocomia spinosa (Arecaceae) Coyol Palm, Grugru Palm, Abeh, Maccafat

Acrocomia spinosa is a name that carries more taxonomic history than pharmacological distinction. Widely treated today as a synonym of Acrocomia aculeata, the Caribbean palm to which it refers has been a source of food, oil, and medicine since pre-Columbian times, when Amerindians began its incipient domestication . The palm's fruit yields an oil rich in oleic acid and carotenoids, its sap ferments into a traditional alcoholic beverage, and its root tea has been used in Brazilian folk medicine for urinary complaints . Modern research on A. aculeata, the accepted name for this complex, has documented anti-inflammatory, antidiabetic, and antithrombotic activities, though virtually all of this work concerns South American populations rather than the Caribbean palm originally described as A. spinosa.

Botanical Description

Acrocomia spinosa is a solitary, erect palm reaching up to 20 metres in height, with a columnar trunk 10 to 40 centimetres in diameter, armed with black, needle-like spines up to 12 centimetres long arranged in irregular rings or scattered bands . The trunk is greyish and marked with leaf scars. The palm is monocaule, meaning it produces a single stem rather than clustering, a feature that distinguishes it from some other oil palms.

Key Identification Features:

The leaves are pinnate, clustered at the crown, and up to 5 metres long. The rachis is armed with black spines up to 6 centimetres long along its entire length. Each leaf bears 120 to 190 pairs of leaflets, which are linear to linear-lanceolate, coriaceous, and glossy green above with a glaucous grey underside . The proximal leaflets are 90 to 100 centimetres long, the median leaflets 80 to 90 centimetres, and the distal leaflets 55 to 60 centimetres.

The inflorescence is interfoliar, a first-order raceme 1.3 to 1.4 metres long, pendulous at anthesis and in fruit. The palm is protandrous, with male and female flowers maturing at different times to promote cross-pollination. The peduncular bract is woody, 80 to 180 centimetres long, orange on the inner surface and densely armed with black spines on the outer surface .

The fruit is a globose to ovoid drupe, 3 to 5 centimetres in diameter, with a green to yellowish exocarp, a fibrous mesocarp, and a hard, black endocarp enclosing a single seed. The mesocarp is rich in oil and carotenoids.

Distribution: The Acrocomia aculeata complex, of which A. spinosa is a synonym, is widespread across the Neotropics, from Mexico (24°N) to Brazil (23°S) . It occurs in tropical and subtropical climates, tolerating short periods of temperatures down to −4°C and annual rainfall as low as 500 millimetres . It is particularly abundant in the Brazilian Cerrado and Pantanal, and is also found in the Caribbean, including Jamaica, where the specimen originally described as A. spinosa was collected .

Conservation Status: The species is not listed as threatened. As a widespread and adaptable palm across the Neotropics, it maintains stable populations and is often abundant in disturbed and open habitats.

Etymology

The generic name Acrocomia is derived from the Greek "akron," meaning tip or extremity, and "kome," meaning hair, a reference to the tuft of fibres or spines at the apex of the trunk or fruit. The specific epithet spinosa is Latin for "thorny" or "spiny," referring to the formidable armature of the trunk, leaves, and inflorescence bracts. The common name "Coyol" derives from the Nahuatl word for the palm, and "Grugru" is a Caribbean name for the weevil larvae that infest the decaying trunks and are considered a delicacy.

5. Phytochemistry

5.1 Fatty Acids

The fixed oil from Acrocomia fruits is dominated by fatty acids, with composition varying by plant part and geographic origin.

Oleic Acid: The major monounsaturated fatty acid in pulp oil, comprising 71.25 percent of total fatty acids in one study . This high oleic acid content is associated with cardioprotective effects.

Lauric Acid: The predominant fatty acid in almond oil, comprising 41.71 to 47.21 percent in A. aculeata fixed oil .

Palmitic Acid: A saturated fatty acid present in significant quantities in both pulp and almond oils.

5.2 Carotenoids and Tocopherols

β-Carotene: The major carotenoid in pulp oil, accounting for approximately 80 percent of total carotenoids, with concentrations of 49 micrograms per gram fresh mesocarp . Total carotenoid concentrations reached 872 micrograms per 100 grams fresh weight in mesocarp and 3,075 micrograms per 100 grams in exocarp of fully ripe fruits .

α-Tocopherol: The principal tocopherol vitamer, present at 213 micrograms per gram total lipids, along with β-, γ-, and δ-tocopherol .

Lutein, Zeaxanthin, Antheraxanthin, Violaxanthin: Additional carotenoids identified in the fruit, contributing to antioxidant activity .

6. Mechanisms of Action

6.1 Anti-inflammatory Activity: Fatty Acid-Mediated Modulation

The anti-inflammatory activity of Acrocomia pulp oil is attributed primarily to its fatty acid composition, particularly the high oleic acid content. Oral administration of the oil significantly inhibited carrageenan-induced paw edema (67 percent) and leukocyte migration into the pleural cavity (91 and 81 percent at 300 and 700 milligrams per kilogram, respectively) . The mechanism likely involves modulation of inflammatory eicosanoid production, as oleic acid can compete with arachidonic acid for incorporation into cell membranes and inhibit pro-inflammatory signaling. The carotenoids and tocopherols in the oil provide additional antioxidant protection that reduces oxidative stress associated with inflammation.

6.2 Antithrombotic Activity: Platelet Function Modulation

The pulp oil demonstrates antiaggregant and anticoagulant effects in in vitro models using human platelet-rich plasma. The oil was tested at concentrations of 50 to 800 micrograms per millilitre and affected platelet aggregation and P-selectin expression . The mechanism is likely related to the oil's fatty acid composition, as oleic acid has documented effects on platelet membrane fluidity and eicosanoid production. The antioxidant compounds in the oil may also reduce platelet activation by scavenging reactive oxygen species that contribute to thrombus formation.

6.3 Antioxidant Activity: Carotenoid and Tocopherol Scavenging

The antioxidant capacity of Acrocomia fruit is directly attributable to its carotenoid and tocopherol content. β-Carotene, the dominant carotenoid, scavenges singlet oxygen and peroxyl radicals, while α-tocopherol is a potent chain-breaking antioxidant in lipid membranes . The combination of these lipophilic antioxidants in the oil matrix provides protection against lipid peroxidation and oxidative damage to cellular components.

6.4 Antidiabetic Activity: Vascular Function Improvement

Acrocomia aculeata extract demonstrated hypoglycemic and antioxidant properties associated with improved vascular function in type 2 diabetic rats . The mechanism may involve enhanced glucose uptake, protection of pancreatic beta cells from oxidative damage, and improvement of endothelial function through antioxidant and anti-inflammatory effects. The high oleic acid content of the oil may also contribute to improved insulin sensitivity.

6.5 Antiparasitic Activity: Membrane Disruption

The fixed oil from A. aculeata almonds showed moderate activity against Leishmania amazonensis with 40 to 42 percent inhibition . Lauric acid, the predominant fatty acid, is known to disrupt microbial and protozoal membranes through its detergent-like properties. However, the activity was moderate, and the oil lacked activity against Trichomonas vaginalis and Trypanosoma cruzi, suggesting selective susceptibility among parasites.
