Résumé
Cedrelopsis grevei is an aromatic medicinal plant from Madagascar used in folk medicine [PMID: 15032374, PMID: 23459148].
Contexte
Cedrelopsis grevei Baill. (Ptaeroxylaceae) is a plant native to Madagascar, with significant populations located in the south of the country [PMID: 24591320, PMID: 18325702].
Usages traditionnels
In Madagascar, the trunk bark extract is empirically used to treat various pathologies, including hypertension and persistent catarrh [PMID: 18325702].
Composés actifs
The plant contains various secondary metabolites: the bark contains coumarins (including isocedrelopsin, 3',4'-dihydrobraylin, microfolicoumarin, obliquin, 8-methoxyobliquin, aesculetin, cedrelopsin, scoparone, cedrecoumarin A and B, and norbraylin) [PMID: 14630167, PMID: 12453517], triterpenoid derivatives (cedashnine), and quassinoids (cedphiline, cedmiline) [PMID: 12943787]. Seeds contain chalcones such as uvangoletin, 5,7-dimethylpinocembrin, cardamonin, flavokawin B, 2'-methoxyhelikrausichalcone, cedreprenone, and cedrediprenone [PMID: 12648541]. Essential oils from the bark include beta-pinene, cis-sesquisabinene hydrate, caryophyllene oxide, 4-epi-cis-dihydroagarofuran, and ishwarol B [PMID: 15032374, PMID: 15248260, PMID: 15809968], while leaf essential oils are dominated by trans-beta-farnesene, beta-pinene, cis-sesquisabinene hydrate, and ar-curcumene [PMID: 15032374].
Mécanisme d'action
C. grevei may improve endothelial vasodilatation by increasing the participation of nitric oxide (NO) and increasing the protein expression of Cu/Zn superoxide dismutase (SOD) [PMID: 18325702, PMID: 14551050].
Preuves cliniques
Preuve DHypertension/Blood Pressure
Oral administration of C. grevei extract in rats prevented the increase of systolic blood pressure (SBP) in aged rats and induced a progressive decrease in SBP in normotensive rats [PMID: 18325702, PMID: 14551050]
Preuve DHepatotoxicity
Methanolic extract of C. grevei leaves demonstrated antioxidant and hepatoprotective effects against cypermethrin-induced oxidative stress and liver damage in male mice [PMID: 26209317]
Preuve DCancer (MCF-7 cell lines)
Leaf essential oil showed cytotoxic activity against human breast cancer cells (IC50=21.5 mg/L) [PMID: 23459148]
The current evidence consists primarily of in vitro studies and animal models (rats and mice), indicating potential antihypertensive, hepatoprotective, and cytotoxic properties. There are no human clinical trials provided.
