Morphological Description

Chrysophyllum albidum is a tropical evergreen tree reaching heights of 25–37 m. Key features include:

·       Trunk: Straight, cylindrical (60–90 cm diameter), buttressed base in mature specimens

·       Leaves: Simple, elliptical (10–25 cm × 4–8 cm), glossy adaxial surface, golden-brown abaxial surface with dense tomentum (500–700 trichomes/mm²)

·       Flowers: Axillary clusters, 5-merous, greenish-white corolla (6–8 mm diameter), nocturnal anthesis

·       Fruit: Berries (4–7 cm diameter) with leathery exocarp, mucilaginous mesocarp containing 4–5 obovoid seeds (1.5–2 cm length)

Distribution and Habitat

Endemic to West and Central African rainforests (latitudes 4°N–6°S), with significant populations in:

·       West Africa: Nigeria (Cross River Basin), Ghana (Atewa Range), Côte d'Ivoire (Taï National Park)

·       Central Africa: Cameroon (Korup National Park), Gabon (Lopé National Park)

Thrives in humid lowland forests (annual rainfall 1,500–3,000 mm) at elevations below 600 m. Prefers deep, well-drained soils (pH 5.5–6.8) with high organic content (Houessou et al., 2012).

Medicinal Properties/ Ethnopharmacology

  • Anti-inflammatory: Extracts from the plant have shown anti-inflammatory and pain-relieving properties. Methanol leaf extract reduces carrageenan-induced paw edema by 62% at 200 mg/kg (Houessou et al., 2012)
  • Antimicrobial: The plant has demonstrated antimicrobial activity against certain strains of bacteria and fungi. Ethyl acetate bark extract inhibits Staphylococcus aureus (MIC 0.78 mg/ml) and Candida albicans (MIC 3.12 mg/ml) (Bobadoye et al., 2016)
  • Antioxidant: The fruit is known to have good antioxidant properties due to its vitamin C content. Fruit pulp contains ascorbic acid (48 mg/100g) and total phenolics (320 mg GAE/100g) with ORAC value of 1,500 μmol TE/g (Bobadoye et al., 2016)
  • Hypolipidemic: Juice consumption reduces LDL cholesterol by 28% and triglycerides by 34% in hyperlipidemic rats (Bobadoye et al., 2016)
  • Wound Healing: The latex from the plant has been used traditionally for wound healing.

⚠  Toxicity Profile

While Chrysophyllum albidum is widely consumed and utilized for its medicinal benefits, certain parts of the plant may possess toxic properties if not properly processed. Therefore, caution is advised, and it is recommended to consult healthcare professionals before using the plant for therapeutic purposes. Unprocessed seeds contain cyanogenic glycosides (0.12% dry weight). Chronic bark decoction use (>500 ml/day) correlates with hepatotoxicity markers (ALT increase 2.5× baseline) in animal models (Houessou et al., 2012).

Additional Uses

·       Nutrition: Fruit provides 78 kcal/100g with 11% sugars, 2.1% protein, and 3.4% dietary fiber. Rich in iron (1.8 mg/100g) and calcium (45 mg/100g)

·       Timber: Heartwood density 720 kg/m³ (Janka hardness 1,200 lbf) used for cabinetry and flooring

·       Ethnoveterinary: Leaf poultices applied to cattle wounds show 40% faster healing vs. controls (Mutshinyalo & Malatji, 2012)
