STUDIES ON THE CHEMICAL CONSTITUENTS OF ACHNATHERUM INEBRIANS

The bio-active constituents from Achnatherum inebrians were obtained.It was extracted with 95% and 60% alcohol distributed by different solvents,isolated via column chromatography on silia gel and purified by crystallization.The structures of the constituents were indentified by means of IR、MS、NMR and chemical methods respectively.Eight compounds were isolated and elucidated as adensine(1),veratroylzygadenine(2),germerine(3),hexadecanoie-2,3-dihydroxyproyl ester(4),3-O-glucoside-veratramine(5),dausterol(6)4′,6,7-trihydroxy-3’,5’-dimeoxy flavone(7),sucrose(8).All the compound were isolated for the first time from the plant.
