ABSTRACT

Objective:

Vernonia anthelmintica,with complicated components,is a common medicine for the treatment of vitiligo.The purpose of this study was to establish and optimize the separation conditions of high performance liquid chromatography fingerprints(HPLC-FPs) for Vernonia anthelmintica(L.) Willd.

Methods:

We investigated the HPLC-FPs of different extraction samples by the retention times and relative areas of common peaks in the fingerprints.

Results:

We established the optimum separation conditions of HPLC-FPs for Vernonia anthelmintica(L.) Willd,and obtained 19 common peaks in the fingerprints.The HPLC-FPs of the 85% ethanol extract were quite similar to those of the semi-bionic extract(SBE) but very different from those of the water extract of Vernonia anthelmintica(L.) Willd.The No.1,4,6,11,12,14 and 16-19 peaks were the endemic ones of the HPLC-FPs of the 85% ethanol extract and SBE of Vernonia anthelmintica(L.) Willd,while No.20-30 were the endemic peaks of the HPLC-FPs of the water extract.

Conclusion:

The results of our study has provided experimental evidence for further investigation into the constituents absorbed into blood,pharmaceutical technology and pharmacodynamics of Vernonia anthelmintica(L.) Willd.
