POLYHYDROXYPREGNANE GLYCOSIDES FROM DREGEA VOLUBILIS
Keywords:Dregea volubilis, Apocynaceae, polyhydroxypregnane glycoside.
AbstractFour known polyhydroxypregnane glycosides, dregeoside Da1 (1), volubiloside A (2), drevoluoside N (3), and volubiloside C (4) were isolated from the methanol extract of the leaves of Dregea volubilis. Their structures were elucidated by 1D-, 2D-NMR, spectra and comparing with those reported in the literature.
