Résumé
Pterocarpus marsupium is a multipurpose forest tree native to India and Sri Lanka, recognized for its antidiabetic and bioactive properties [PMID:35161227, PMID:15707762].
Contexte
Pterocarpus marsupium Roxb. (Fabaceae) is a valuable medicinal tree in India and Sri Lanka, primarily utilized for its heartwood and stem bark [PMID:35161227]. Due to overexploitation for its multipurpose properties and low seed germination, it is listed as an endangered plant species [PMID:35161227].
Usages traditionnels
In Ayurveda, heartwood extract of Pterocarpus marsupium has been used to treat diabetes, leprosy, asthma, and bronchitis [PMID:36295849]. It is also cited as a significant plant in the Indian traditional system of medicine for the treatment of hyperglycemia [PMID:24074231].
Composés actifs
Bioactive compounds include phenols, flavonoids, and terpenoids [PMID:36295849]. Specific identified compounds include pterostilbene (3,5-dimethoxy-4'-hydroxystilbene) [PMID:30591102], marsupsin, pterosupin [PMID:9214733], and 7-O-alpha-L-rhamnopyranosyl oxy-4'-methoxy-5-hydroxy isoflavone [PMID:15707762]. Additionally, alpha-dihydroxychalcone-glycoside (alpha-DHC) has been isolated from the heartwood [PMID:24675710].
Mécanisme d'action
The herb may lower blood glucose by upregulating Glut-4 and PPAR gamma gene expression [PMID:15707762] and inhibiting dipeptidyl peptidase-4 (DPP-4), which prevents the degradation of glucagon-like peptide-1 (GLP-1) [PMID:24074231, PMID:38024536]. It also exhibits antioxidant activity by reducing oxyradicals [PMID:36295849] and inhibiting aldose reductase activity to prevent sorbitol accumulation [PMID:29556442, PMID:28725625]. Anti-inflammatory effects are mediated via inhibition of LPS-induced MAPK activation and downregulation of COX-2 and iNOS [PMID:24675710].
Preuves cliniques
Preuve BNon-insulin-dependent diabetes mellitus
A multicentric study by the Indian Council of Medical Research found a Pterocarpus marsupium preparation effective in reducing blood glucose and glycosylated haemoglobin levels [PMID:10748962].
Preuve DHyperglycemia (Animal Model)
Butanol subfractions of alcohol extract and phenolic constituents like marsupsin and pterostilbene significantly lowered blood glucose in diabetic rats [PMID:16397913, PMID:9214733].
Preuve DPolycystic Ovary Syndrome (Animal Model)
Methanolic extract restored biochemical parameters and diminished ovarian cysts in testosterone propionate-induced PCOS rats [PMID:28901866].
Preuve DDiabetic Cataract (Animal Model)
Bark extracts provided a protective effect against cataracts by inhibiting aldose reductase activity in diabetic rats [PMID:29556442].
Preuve DAlzheimer's Disease (Animal Model)
Extracts (200-400mg/kg) showed neuroprotective roles in ameliorating streptozotocin-induced AD via DPP-4 inhibition [PMID:24667360].
Sécurité et effets indésirables
In a randomized, double-blind, placebo-controlled study of 60 healthy adults, a standardized extract containing 90% pterostilbene (200 mg/day) was found to be clinically safe, with hematological, lipid, glycemic, thyroid, liver, and renal functions remaining within normal ranges [PMID:37671486].
Synthèse des preuves
Evidence is strongest for antidiabetic activity, supported by a multicentric clinical study and numerous animal/in vitro models. Safety has been demonstrated in a small-scale RCT for healthy adults. Other therapeutic claims (PCOS, AD, cataracts) are currently limited to animal models.
