STUDIES ON THE CHEMICAL CONSTITUENTS OF CYNANCHUM THESIOIDES
-
Abstract
Fourteen constituents were isolated from Cynanchum thesioides(Freyn)K. Schum. Onthe basis of chemical and spectral data, seven of them have been identified including two new com-pounds:glyeeride-1,3-dipalmito-2-sorbate (4), and thesoide (7); and five known compounds:amyrin acetate (1), lupeol acetate (2), α-amyrin caprylate (3), tamarixetin (5) and tamarixetin-3-O-β-D-galacto-pyranoside (6).
