Chemical constituents from lipophilic parts in roots of Angelica dahurica cv.Yubaizhi / 中国中药杂志

ABSTRACT

The chemical constituents from lipophilic parts in the roots of Angelica dahurica cv. Yubaizhi were studied in this paper. The compounds were separated and purified by repeated column chromatographic methods on silica gel and HPLC, and the chemical structures of compounds were determined by spectral data analyses. Thirty-three compounds were obtained and identified as isoimperatorin (1), imperatorin (2), stigmasterol (3), isooxypeucedanin (4), pabulenol (5), psoralen (6), bergapten (7), isodemethylfuropinarine (8), phellopterin (9), osthenol (10), alloimperatorin (11), xanthotoxin (12), xanthotoxol (13), isopimpinellin (14), alloisoimperatorin (15), β-sitosterol (16), oxyalloimperatorin (17), pabularinone (18), 5-hydroxy-8-methoxypsoralen (19), columbianetin (20), heracol (21), isogosferol (22), 2″R-neobyakangelicol (23), byakangelicin ethoxide (24), byakangelicin (25), oxypeucedanin hydrate (26), uracil (27), umbelliferone (28), bergaptol (29), demethylfuropinarine (30), isobyakangelicol (31), oxypeucedanin ethanolate (32), heraclenol (33). Among them, compounds 8, 10, 17, 21, and 30 were obtained from the roots of title plant for the first time.
