Abstract: From the bark of Uncariaguianensis, two new quinovicacidglycosides, quinovicacid 3β-O-β-d-quinovopyranoside and quinovicacid 3β-O-β-d-fucopyranosyl-(27 → 1)-β-d-glucopyranosylester, have been isolated, in addition to known quinovicacid 3β-O-[β-d-glucopyranosyl-(1 → 3)-β-d-fucopyranosyl]-(27 → 1)-β-d-glucopyranosyl ester and quinovicacid 3β-O-β-d-fucopyranoside. Their structures were elucidated by spectral and chemical studies.
