Abstract:Objective:To study the chemical constituents of the rhizomes of Atractylodes macrocephala .Methods:Repeated column chromatography on silica gel and HPLC were applied to the separation of compounds and their structures were determined by spectroscopic data analyses of MS and NMR.Results:Nine compounds were obtained and identified as atractylon(1),atractylenolide Ⅰ(2),biatractylenolide(3),atractylenolide Ⅱ(4),atractylenolactam(5),atractylenolide Ⅲ(6),4R,15-epoxylatractylenolide Ⅱ(7),4R,15-epoxy-8β-hydroxylatractylenolide Ⅱ(8),and 8β,9α-dihydroxylatractylenolide Ⅱ(9),respectively.Conclusion:Compound 7 was a new natural product and compound 9 was isolated from the rhizomes of A.macrocephala for the first time. |
