ABSTRACT

Objective:

To establish a method for the determination of 13 active components (phellodendrine, chlorogenic acid, magnoflorine, geniposide, coptisine, epiberberine, jatrorrhizine, berberine, palmatine, baicalin, wogonoside, wogonin, and oroxylin A) in Huanglian Jiedu Decoction (HJD) by HPLC, and screen the effective fractions of HJD by the content and ratio of active components.

Methods:

The freeze-dried powder of HJD water decoction was extracted by petroleum ether, ethyl acetate, n-butanol and pure water by soxhlet extractor combined system solvent extraction method. The different polar fractions of HJD were obtained after drying, and the residue was used as the precipitation fraction. Subsequently, 13 active ingredients in HJD were detected by Agilent 1260 high performance liquid chromatography. Furthermore, the content of active components in HJD and its different polar fractions were detected, and the effective fraction of HJD were screened.

Results:

A stable and reliable HPLC method was successfully established, and the content of active components in HJD from high to low were geniposide, berberine, palmatine, baicalin, wogonoside, coptisine, jatrorrhizine, epiberberine, magnoflorine, phellodendrine, wogonin, chlorogenic acid, and oroxylin A. Compared with the fractions of petroleum ether, ethyl acetate, purified water, and precipitation, the total content of active components in the fraction of n-butanol of HJD was the highest and its proportion is the closest to that of HJD, which was the effective fraction of HJD.

Conclusion:

In this study, a method for the determination of 13 active ingredients in HJD by HPLC was successfully established, and the n-butanol fraction of HJD was selected as the effective fraction of HJD based on the content of active components.
