| Abstract | ||||
| Seven known quinovic acid glycosides were isolated for the first time from the n-BuOH fraction of the 70% ethanol ext. of Zygophyllum aegyptium A. Hosny sp. nov. These compds. were identified as: quinovic acid 3β-O-β-D-quinovopyranoside, quinovic acid 3β-O-β-D-glucopyranoside, 3-O-[α-L-arabinosyl-(1→2)-β-D-quinovopyranosyl]quinovic acid , 3-β-O-β-D-quinovopyranosylquinovic acid-28-O-β-D-glucopyranosyl ester, 3-β-O-[β-D-2-O-sulfonyl quinovopyranosyl]-quinovic acid-28-O-β-D-glucopyranosyl ester (zygophyloside F), 3-β-O-β-D-glucopyranosylquinovic acid 28-O-β-D-glucopyranosyl ester , 3β-O-[β-D-2-O-sulfonyl glucopyranosyl]-quinovic acid-28-O-[β-D-glucopyranosyl] ester (zygophyloside G), in addn. to, β-sitosterol glucoside. The structure elucidation of these compds. was detd. by phys., chem. and spectroscopic methods. | ||||
