Abstract

The invention provides a fingerprint control method of low-sugar type strong loquat loquat, which relates to the technical field of drug quality control, and comprises the following steps: the first step is to establish a standard characteristic map of components in the low-sugar type strong loquat loquat; the second step is to use the same The method is used to determine the characteristic spectrum of the low-sugar type strong loquat to be tested; the third step is to compare the characteristic spectrum of the low-sugar type strong loquat to be tested with the characteristic spectrum of the standard low-sugar type strong loquat to determine the quality and authenticity. The beneficial effects of the present invention are: 1. Integrity, macroscopicity and ambiguity. The present invention overcomes the difficulty in reflecting the real feeding situation of products in the measurement of individual components. The present invention provides a new method and means for complete and accurate evaluation of the quality of Qiangli Loquat Loquat; 2. Visually and intuitively distinguish the similarities and differences of the spectra; semi-quantitative indicators are used to quantify the authenticity, quality, and quality of samples.

Description

technical field [0001] The invention relates to the technical field of medicine quality control, in particular to a fingerprint control method of low-sugar strong loquat dew. Background technique [0002] Qiangli Loquat Loquat is composed of loquat leaves, poppy shells, Baibu, Baiqian and other seven traditional Chinese medicines. It is a variety recorded in the second volume of the Ministry of Health's standard "Chinese Medicine Prescriptions and Preparations"; it has the effects of nourishing yin and restraining lungs, antitussive and expectorant ; For the treatment of chronic cough, labor cough, bronchitis, etc. Among them, loquat leaf is the monarch medicine, and poppy shell is the main medicine for treating cough in the prescription, which contains alkaloid components such as morphine, codeine, papaverine, papaverine, and protoopine. [0003] As we all know, the efficacy of Chinese patent medicine does not come from any single active ingredient, but the result of the j...
