Problems solved by technology

[0003] The 2015 edition of the "Chinese Pharmacopoeia" only uses tulimoside A as the content determination index. Due to the diversity and complexity of active ingredients in traditional Chinese medicine, the content determination of a single component is difficult to fully reflect the internal quality of the medicinal material, and it also lacks specificity
At present, the research on fingerprint / characteristic spectrum and content determination of Fritillaria adopts high performance liquid chromatography (HPLC method). This method takes a long time, has low sensitivity and limited separation ability, and can no longer solve the complex analysis process of traditional Chinese medicine. practical problems in

Abstract

The present invention relates to a method for constructing the UPLC characteristic map of the soil fritillary medicinal material and a method for determining the component content thereof. The method for determining the component content of the soil fritillary medicinal material comprises the following steps: (1) absorbing the reference substance solution and the to-be-tested solution respectively The sample solution of Tuifumu medicinal material was injected into the ultra-high performance liquid chromatograph, and the corresponding peak area was measured; (2) The content of Tuifumoside A was calculated by the external standard method; B. The content of Tuimoside C. In the present invention, the peak area is measured by constructing the UPLC characteristic map of the medicinal material Fritillaria chinensis, and the content of fritillin A is calculated by the external standard method, and then the contents of fritillin B and C are calculated by one test and multiple evaluations. , fundamentally quickly and accurately carry out quantitative and qualitative analysis of Soil Fritillaria, which has certain characteristics. The method described in the present invention is fast, stable and specific, and has a stable baseline, providing scientific basis for the quality control of Soil Fritillaria. new method.

Description

technical field [0001] The invention belongs to the field of identification of traditional Chinese medicines, and in particular relates to a method for constructing a UPLC characteristic map of a soil fritillary medicinal material and a method for determining its component content. Background technique [0002] Fritillaria is commonly known as wild melon, also known as false fritillary, grass fritillary, ground bitter gall, etc. It was originally recorded in "Supplements to Compendium of Materia Medica" compiled by Zhao in the Qing Dynasty. The 2015 edition of "Chinese Pharmacopoeia" stipulates that fritillaria is calabash The dry tubers of the family plant Fritillaria are widely distributed in Hebei, Shanxi, Shandong, Henan, Hubei, Hunan and other places. It is reported in the literature that a variety of saponins, sterols and their glycosides, esters, alkaloids, flavonoids and other components have been isolated from Fritillaria, among which saponins are the main active co...
