摘要
Objective To study the chemical constituents from Millettia speciosa. Methods The compounds were isolated and purified by silica gel, Sephadex LH-20, ODS column chromatography, and recrystallization. The structures were identified using physicochemical and spectral data. Results Thirteen compounds were isolated from M. speciosa and identified as docosanoic acid （1）, tetracosane （2）, octadecane （3）, hexacosanoic acid （4）, β-sitosteroi acetate （5）, β-sitosterol （6）, syringin （7）, maackiain （8）, formononetin （9）, ψ-baptigenin （10）, rotundic acid （11）, pedunculoside （12）, and daucosterol （13）. Conclusion Compounds 5, 7, and 10-12 are obtained from this plant for the first time.
