Chinese Journal of Natural Medicines,2010,8(4):270-273. | Chemical Constituents from the Roots of Dysoxylum densiflorum.[Reference: WebLink] | To investigate the chemical constituents in the roots of Dysoxylum densiflorum(Blume) Miq.. METHODS AND RESULTS: :Chromatographic methods were used for separation,and spectroscopic techniques for the identification of isolated compounds. Thirteen compounds were isolated and identified as β-amyrenone(1),richenone(2),β-sitosterol(3),cabraleadiol(4),β-amyrin(5),hydroxydammarenone-Ⅱ(6),cabraleadiol monoacetate(7),ocotillone(8),3β-hydroxy-5-pregnen-20-one(9),3β-hydroxy-5α-pregnan-20-one(10),cabraleahydroxylactone(Cabraleahydroxylactone acetate
,11),toosendansterol B(12) and(-)-epicatechin(13). CONCLUSIONS: Steroids,triterpenoids and flavonoids are the major constituents of the roots in Dysoxylum densiflorum.Compounds 1-13 were reported from this plant for the first time,and toosendansterol B(12) from the genus of Dysoxylum for the first time. |
