) and their close relative Danpi(Paeonia Suffruticosa Andr) samples were estimated quantitatively,based on their UV fingerprint spectra of the extracts obtained with chloroform,ethanol and water,by applying the common and variation peak ratio dual index sequence analysis method.

Objective: To set up the dual-index sequence analytical method for UV fingerprint spectra (FPS) in which the dual indices are common peak ratio and variant ration.

The products quality of different pharmaceutical factories (Guangdong Yifang, Jiangyin Tianjiang, Sanjiu Yiyao, Hongkong Purapharm) could be revealed directly in the FTIR spectra.

Study on IR fingerprint of 13 kinds of Chinese medicinal granules;

Studies on IR fingerprint of Tongren Dahuoluo pills and Tongren Niuhuangqingxin pills;

Study on IR fingerprint of Tongren Wujibaifeng Pills and Xiaoshuanzaizao Pills;

Dual-index sequence analytical method for IR fingerprint spectra of the chloroform extract of Radix Glycyrrhizae;

AIM: To set up a new method to analyze IR fingerprint spectra, which was in line with the cha racteristic of traditional Chinese medicine.
