POLYHYDROXYPREGNANE GLYCOSIDES FROM DREGEA VOLUBILIS

Phan Van Kiem, Phan Tuan Phuong

Abstract


Four 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.


Keywords
