picramnia/glycoside

Cytotoxicity-based, bioassay-guided fractionation of the chloroform-soluble extracts of both the roots and leaves of Picramnia latifolia led to the isolation of two new anthrone C-glycosides, picramniosides G (1) and H (2), two new oxanthrone C-glycosides, mayosides D (3) and E (4), and a new

A bioactivity guided fractionation, using KB cells and brine shrimp assays, of the methanolic extract from the leaves of Picramnia antidesma yielded two known anthraquinones, aloe-emodin and aloe-emodin anthrone, and three new aloe-emodin C-glycosides, named picramnioside A, picramnioside B and

Activity-guided investigation of crude extracts prepared from the root bark of Picramnia antidesma, a medicinal plant long used for the treatment of malaria in tropical areas of the Americas, when tested on KB cells led to the isolation of a new compound, 10-epi-uveoside, from a cytotoxic fraction
