Structures of New Quassinoid Glycosides, Yadanziosides A, B, C, D, E, G, H, and New Quassinoids, Dehydrobrusatol and Dehydrobruceantinol fromBrucea javanica(L.) MERR
Eight new antileukemic quassinoid glycosides, yadanziosides A-H (1-8) were isolated from seeds of Brucea javanica and their structures were determined by chemical transformation and spectral analysis.
Structures of New Quassinoid Glycosides, Yadanziosides A, B, C, D, E, G, H, and New Quassinoids, Dehydrobrusatol and Dehydrobruceantinol from<i>Brucea javanica</i>(L.) MERR
Quassinoid glycosides, yadanziosides A, B, C, D, E, G, and H, and two quassinoids, dehydrobrusatol and dehydrobruceantinol were isolated from seeds of Brucea javanica, and their structures were determined. These glycosides showed bitter taste and were demonstrated to have antileukemic activity.
