Cytotoxic Anthraquinone Derivatives from Picramnia antidesma

Planta Medica, 2002
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 containing a rich mixture of anthrone glycosides.

Bioactive anthraquinone glycosides from Picramnia antidesma ssp. Fessonia

Phytochemistry, 1995
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 picramnioside C.

Diastereomeric C-glycosyloxanthrones from picramnia antidesma

Phytochemistry, 1999
Nine compounds were isolated and identified from the stem of Picramnia antidesma. Two of the isolated compounds: mayoside and saroside, which is new, are diastereoisomeric oxanthrones. The structure of saroside has been obtained on the basis of spectroscopic evidence.
