OBJECTIVE: To study the effective components in the root of Pimpinella thellungiana METHOD: Column chromatography with silica gel and ODS was employed for the isolation and purification of ingredients. Their structures were elucidated by spectral analysis. RESULT: Three compounds were obtained and identified as 2-(1',2'-epoxy)-4-methoxy pheryl-2-methyl-butyrate(I),4-(1'-propenyl) phenol(II) and 2-methyl butyric acid(III). CONCLUSION: Compound I is a new compound and named thellungianin G. Compounds II and III were separated from P. Thellungiana for the first time.
