Objective To investigate the chemical constituents from the pods of Glycine max. Methods The chemical constituents were isolated by repeated silica gel chromatography, Sephadex LH-20 gel column chromatography, medium pressure column chromatography, and semi-preparative liquid chromatography. Their structures were elucidated by chemical properties and spectroscopic analyses. Results Fourteen compounds were identified to be 4,4'-diphenylmethane-bis (ethyl) carbamates (1), 2,6-dimethoxy-1,4-benzoquinone (2), (+)-medioresinol (3), taraxerone (4), lupenone (5), 7,3',4'-trihydroxyflavone (6), coumestrol (7), indole-3-carboxylic acid (8), apigenin (9), phaseol (10), 7,4'-dihydroxyflavone (11), stigmasterol (12), β-sitosterol (13), and β-daucosterol (14). Conclusion Compounds 1—5 are obtained from the pods of G. max for the first time, and compound 6 is obtained from this plant for the first time.
