New pregnane glycosides from Caralluma hexagona Lavranos and their in vitro α-glucosidase and pancreatic lipase inhibitory effects

Three new pregnane glycosides in addition to four known compounds were isolated from the methylene chloride fraction of Caralluma hexagona Lavranos using bioassay-guided fractionation. The new compounds were identified as 12,20-di-O-benzoyl-3β,8β,12β,14β,20-pentahydroxy-(20R)-pregn-5-ene-3-O-β-d-glucopyranosyl-(1→4)-β-d-digitaloside (1), 3β,8β,14β,20-tetrahydroxy...
