Bioactive anthraquinone glycosides from Picramnia antidesma ssp. Fessonia
Phytochemistry, 1995A 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.

A new species ofPicramnia (Picramniaceae) is described, illustrated, and compared to related Amazonian species. The new species,Picramnia coccinea, is known only from three localities in three adjacent municipalities near Ilheus, Bahia, and constitutes another example of endemism in the southern Bahian flora.

In this study, HPLC-PDA-HRMS-SPE-NMR data were used for initial analysis of the CH2Cl2 fraction of an EtOH extract of the leaves of Picramnia glazioviana. The HRMS, UV, and NMR data obtained from the HPLC-PDA-HRMS-SPE-NMR analysis were used to direct semipreparative HPLC isolation toward nortriterpenoids, which resulted in the isolation of 18 new and ...
