Abstract: Column chromatography of silical gel and Sephadex LH-20 methods were used to isolate and purify the chemical constituents from the rhizome of Polygonatum odoratum.The four known rare C-methylated and O-methylated homoisoflavanones were isolated and characterized.The structure of the compound were elucidated by spectroscopic and the data reported in literature.The four methyl-homoisoflavanones were determined as 4'-methoxy-5,7-dihydroxy-6,8-dimethyl-homoisflavanone(Ⅰ),4',5,7-trihydroxy-6,8-dimethyl-homoisflavanone(Ⅱ),4',5,7-trihydroxy-6-methyl-8-methoxy-homoisflavanone(Ⅲ) and 4',5,7-trihydroxy-6-methyl-homoisflavanone(Ⅳ).Compound Ⅰand Ⅳ were isolated from the Polygonatum genus for the first time.

Key words: Polygonatum odoratum, homoisoflavanones, isolation and purification, structure identification
