Abstract

The invention provides an HPLC fingerprint spectrum of wine steamed coptidis rhizoma. The HPLC fingerprint spectrum is detected by adopting HPLC. A detection method comprises the steps of 1) preparinga reference solution; 2) preparing a test solution; and 3) sucking the reference solution and the test solution to be injected into a liquid chromatograph, and recording a chromatogram. According tothe detection method for the HPLC fingerprint spectrum of the wine steamed coptidis rhizoma, the established fingerprint spectrum has strong specificity and is strong in characteristic peak regularityand good in consistency; the detection method can be used as a quality evaluation method of the wine steamed coptidis rhizome, and also can be used for measuring the content of groenlandicine, columbamine, epiberberine, jatrorrhizine hydrochloride, coptisine hydrochloride, palmatine hydrochloride, berberine hydrochloride and / or berberrubine in the wine steamed coptidis rhizome; and the wine steamed coptidis rhizoma can be effectively identified.

Description

technical field [0001] The invention specifically relates to an HPLC fingerprint detection method of wine-steamed Coptidis rhizoma. Background technique [0002] Traditional Chinese medicine (TCM) is a medicine produced under the guidance of TCM theory, which is a collection of many chemical substances, and is effective in one or more of these components. Therefore, it is difficult to truly reflect the pleiotropic effects and integrity of traditional Chinese medicines, and it is difficult to accurately reflect the internal comprehensive quality of traditional Chinese medicines with the existing quality evaluation methods. Therefore, the quality control model of simultaneous determination of multiple components has become the key to the quality control of traditional Chinese medicine in the future. Quantitative analysis of multi-indicator components is the most direct method for quality control of traditional Chinese medicine, which can reveal the change of chemical componen...
