[Separation and identification of thellungianin G from the root of Pimpinella thellungiana Wolff].

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.
