Abstract:

To establish UV fingerprint method of measuring Gongyingqinglan mixture quality,UV fingerprints were got using ultraviolet spectrophotometer scanning ten Gongyingqinglan mixture,and the correlation coefficient method was used to calculate the similarity between Gongyingqinglan mixture sample fingerprints and contrasted fingerprint. The results showed that the UV fingerprint absorbance of samples that chlorogenic acid content conformed with the provisions were 0.165-0.265 Abs (317.00 nm),0.162-0.285 Abs (282.00 nm) and 0.137-0.240 Abs (259.00 nm),and the fingerprint similarity was above 0.910.While the UV fingerprint absorbance of samples that chlorogenic acid content was not in conformity with the provisions did not meet this condition of 0.165-0.265 Abs (317.00 nm),0.162-0.285 Abs (282.00 nm) and 0.137-0.240 Abs (259.00 nm) or the fingerprint similarity were below 0.910.This method could be used to control the quality of the Gongyingqinglan mixture.

Key words: Gongyingqinglan mixture; fingerprint; chlorogenic acid; quality standard
