Quinovic acid glycosides from Uncaria guianensis.
From the bark of Uncaria guianensis, two new quinovic acid glycosides, quinovic acid 3 beta-O-beta-D-quinovopyranoside and quinovic acid 3 beta-O-beta-D-fucopyranosyl-(27----1)-beta-D-glucopyranosylester, have been isolated, in addition to known quinovic acid 3 beta-O-[beta-D-glucopyranosyl-(1----3)-beta-D-fucopyranosyl]-(27----1)- beta-D-glucopyranosylester and quinovic acid 3 beta-O-beta-D-fucopyranoside. Their structures were elucidated by spectral and chemical studies.
