Besides the two known saponins, quinovic acid-3β-O-β-D-quinovoside and 3β-O-β-D-quinovopyranosyl quinovic acid (28→1)β-D-glycopyranosyl ester, two new glycosides having the structure quinovic acid 3β-O-β-D-quinovopyranosyl(3→1)β-D-xylopyranoside and 3β-O-β-D-quinovopyranosylquinovic acid (28→1)quinovopyranosyl ester were isolated from the aerial parts of Z. album growing in Egypt. The structures were elucidated on the basis of hydrolytic and spectral methods.
