From the roots of Adina rubella, four new quinovic acid glycosides, quinovic acid 3-O-β-D-glucopyranosyl(1→4)-β-D-fucopyranoside, quinovic acid 3-O-β-D-glucopyranosyl(1→4)-β-D-fucopyranosyl-(28→1)-β-D- glucopyranosyl ester, quinovic acid 3-O-β-D-glucopyranosyl(1→4)-α-L- rhamnopyranosyl-(28→1)-β-D-glucopyranosyl ester and quinovic acid 3-O-β- D-glucopyranosyl(1→2)-β-D-glucopyranosyl-(28→1)-β-D-glucopyranosyl ester, were isolated. Their structures were elucidated on the basis of hydrolytic and spectral methods.
