Abstract

Objective: To study the chemical constituents of the flowers of Bupleurum chinese.

Methods: The compounds were separated by column chromatography with silica gel. Their structures were identified by spectral methods and chemical analysis.

Results: Five compounds were isolated and identified as 8-(3',6'-dimethoxy)-4,5-cyclohexadiene-(delta11,12-dioxide-methylene) -dense-dihydrogen-isocoumarin(I), quercetin(II), rutin(III), calcifenol (IV), isorhamnetin (V).

Conclusion: Compounds I and IV are obtained from the genus for the first time. Compound I is a new compound.
