Chemical constituents from the roots tuber of Aconitum ouvrardianum / 中成药

ABSTRACT

AIM To study the chemical constituents from the roots tuber of Aconitum ouvrardianum H..METHODS The ethyl acetate fraction of methy extract from A.ouvrardianum roots tuber was isolated and purified by silica,aluminium oxide column,Sephadex LH-20,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Eighteen compounds were isolated and identified as kongboendine (1),anisoezochasmaconitine (2),lipo-14-O-anisoylbikhaconine (3),franchetine (4),talatisamine (5),chasmanine (6),crassicauline A (7),chasmaconitine (8),14-dehydrotalatisamine (9),lipoindaconitine (10),indaconitine (11),yunaconitine (12),lipoyunaconitine (13),liljestrandisine (14),transconitine B (15),ouvrardiantine (16),atropurpursine (17),8-deacetylyunaconitine (18).CONCLUSION Compounds 1-4,9-10,13,15,17 are isolated from this plant for the first time.
