Abstract

The invention relates to an HPLC fingerprint spectrum of Saussurea involucrate and a method for establishing a DNA fingerprint spectrum of the Saussurea involucrate. The invention is characterized in that the HPLC fingerprint spectrum comprises fingerprint spectrums of two extraction positions with different polarities of ethyl acetate and n-butyl alcohol, and the fingerprint spectrum of the extraction position of the ethyl acetate has 20 common peaks, wherein 7 peaks refer to scopoletin, rutoside, isoquercitrin, xylostein, quercetrin, homoplantaginin and hispidulin respectively; the fingerprint spectrum of the extraction position of the n-butyl alcohol has 11 common peaks, wherein 3 peaks refer to bergapten, scopoletin and rutoside; and the DNA fingerprint spectrum consists of an RAPD molecular fingerprint spectrum and an ISSR molecular fingerprint spectrum. The quality and the reality and falsity of the Saussurea involucrate can be universally and effectively detected in the aspects of chemistry and biology by combination of HPLC fingerprint and DNA fingerprint.

Description

technical field [0001] The invention relates to a method for establishing an HPLC fingerprint and a DNA fingerprint of Xinjiang snow lotus, which can detect the quality of Xinjiang snow lotus from two angles of chemistry and biology. Background technique [0002] Xinjiang snow lotus whole herb is used as medicine, which is the mainstream variety of snow lotus medicinal materials. Snow lotus has a long history of medicinal use. It is sweet, bitter, and warm, and belongs to the liver, spleen, and kidney meridians. It has the effects of clearing away heat and detoxification, expelling wind and dampness, promoting menstruation and promoting blood circulation, strengthening muscles and yang, anti-inflammatory and analgesic, warming the palace and dispelling cold; it is used for rheumatoid arthritis, cold palace abdominal pain, amenorrhea, retained placenta, stroke, kidney deficiency low back pain, Nocturnal emission, impotence, measles impotence, lung-cold cough, high mountain i...
