Résumé
Sphenocentrum jollyanum is a West African shrub from the Menispermaceae family used in folk medicine for various ailments, including wounds and diabetes [PMID:28930265].
Contexte
S. jollyanum is a shrub native to the tropical forest zones of West Africa, thriving in deep shade and cultivated in countries such as Cameroon, Sierra Leone, Nigeria, Ghana, and Côte d'Ivoire [PMID:28930265]. It is characterized by bright yellow roots and wedge-shaped leaves [PMID:35398496].
Usages traditionnels
It is employed in folk medicine to treat wounds, fever, coughs, high blood pressure, breast tumors, constipation, and as an aphrodisiac [PMID:28930265]. It is specifically reputed for dressing chronic wounds [PMID:35398496] and is used traditionally in combination of stem and leaves to treat chronic wounds and diabetes mellitus [PMID:36791929]. Leaf extracts are also used for erectile dysfunction, gastrointestinal disorders, and malaria [PMID:40064323].
Composés actifs
Phytochemical investigations identify secondary metabolites including alkaloids, saponins, flavonoids, and annin [PMID:28930265]. Specific isolated compounds include furanoditerpenes (columbin, isocolumbin, fibleucin) [PMID:16236477], 1,4-polyisoprene [PMID:36791929], and various ecdysteroids such as Sphenocentroside A and B, polypodoaurein, polypodine B, ecdysterone, 20, 26-dihydroxyecdysone, 20-hydroxyecdysone, and atrotosterone A [PMID:31326452, PMID:32165210].
Mécanisme d'action
The plant exhibits anti-inflammatory activity, with fruit methanol extracts and furanoditerpenes (columbin) inhibiting carrageenan-induced hind paw oedema [PMID:16236477]. Aqueous root and leaf extracts facilitate wound healing by modulating pro-inflammatory cytokines and vascular endothelial growth factor (VEGF) [PMID:35398496]. Leaf extracts demonstrate mitochondrial-restorative influences and modulate apoptosis in diabetic models [PMID:40064323]. Seed extracts exhibit urease inhibitory and antacid activities [PMID:32165210].
Preuves cliniques
Preuve DWound Healing (Diabetic Rats)
A 0.10% w/w 1,4-polyisoprene-based ointment caused 99% wound closure by day 12 and significantly increased tensile strength [PMID:36791929].
Preuve DInflammation (Rats)
Fruit methanol extract (79.58% inhibition) and root extract (53.75% inhibition) showed significant anti-inflammatory activity in carrageenan-induced oedema models [PMID:16236477].
Preuve DAntimicrobial Activity (In vitro)
Methanol extract of root showed 98% activity against Aspergillus fumigatus Pinh and 80% against Vancomycin resistant enterococcus (VRE) at 200 μg/mL [PMID:31326452].
Preuve DMale Reproductive Activity (Rats)
Oral administration of root extract (50-150 mg/kg) caused a dose-dependent significant reduction in progressive motility, viability, and total sperm counts [PMID:29699257].
Preuve DMalaria-induced Oxidative Stress (Mice)
Methanolic leaf extract significantly reduced levels of total protein, AST, ALT, ALP, GGT, and malondialdehyde, while increasing catalase, SOD, and GSH levels in P. berghei infected mice [PMID:23625415].
Sécurité et effets indésirables
In rat models, root extract administration (50-150 mg/kg) resulted in a dose-dependent reduction in sperm count, motility, and viability [PMID:29699257].
Synthèse des preuves
The current evidence consists primarily of in vitro studies and animal models (rats and mice), indicating potential anti-inflammatory, wound-healing, and antimicrobial properties, but also suggesting potential reproductive toxicity in males. No human clinical trials were provided.
