AbstractFour new compounds named hemoside A, B, C and D were isolated from the roots of Metaplexis hemsleyana Oliv. (Asclepiadaceae). Their chemical structures were determined as 12, 20-dibenzoylsarcostin 3-O-beta-D-cymaropyranoside(1), 12,20-dibenzoylsarcostin 3-O -beta-D-thevetopyranosyl(1-->4)-beta-D-oleandropyranosyl(1-->4)-beta-D cymaropyranoside(2), 12-acetyl-20-benzoylsarcostin 3-O-beta-D-thevetopyranosyl(1--> 4)-beta-D-oleandroplyranosyl(1-->4)-beta-D-cymaropyranoside(3) and gymnemarsgenin 3-O-beta -D-thevetopyranosyl(1-->4)-beta-D-oleandropyranosyl(1-->4)-beta-D cymaropyranoside(4) respectively by means of NMR and other spectral and chemical methods.
