Two quassinoid glucosides from Castela tortuosa

Phytochemistry, 1992
Abstract The structures for two new bitter-tasting quassinoid glucosides, casteloside A (chaparrin-2- O -β- d -glucopyranoside) and casteloside B (glaucarubol-2- O -β- d -glucopyranoside) isolated from the bark of Castela tortuosa , a medicinal plant known as ‘chaparro amargo’ in Mexico, were determined by spectral analyses, in particular, NMR data.
