Problems solved by technology

[0005] Although literature [9, 10] involves the determination of laxative potency based on the mouse model of compound diphenoxylate constipation, the literature uses the crude extract of rhubarb decoction for administration, which cannot specifically reflect the The laxative intensity of individual laxative components, which cannot be correlated with their content determination results
So a rough measure of potency

Embodiment 3

[0145] Embodiment 3 (the detailed investigation of the mensuration of rhubarb-induced laxative effect component potency and the calculation of equivalence coefficient)

[0146] 140 ICR male mice, weighing 20g, were divided into 14 groups, 10 in each group. They were fasted for 12 hours before the experiment, and the first group was regarded as the normal group, without any modeling and administration; the second group As a model control group, only the compound difenoxate tablet was given to cause a constipation model; the remaining 12 groups were administered corresponding to 12 effect components. First use compound diphenoxylate tablet (dose 60mg·kg -1 ) for modeling by intragastric administration, and intragastric administration after 1 hour of modeling, with a dosage of 0.4ml (wherein the concentrations of 12 active ingredients such as aloe-emodin-8-o-β-D-glucoside and sennoside A are 1 mg / ml, dissolved in hot water at 37°C), after administration, fasting without water, a...

Abstract

The application of the invention provides a multi-component comprehensively quantificational method for assessing and controlling the quality of traditional Chinese medicine and application. The method for assessing and controlling the quality of traditional Chinese medicine combines measurement of chemical content and measurement of biological potency, focuses on comprehensively quantificational assessment on the quality of the rheum palmatum herbs or medicinal slices through biological potency, and establishes the equivalent computation method for components causing the rheum palmatum purgative effect; the method can be applied to preliminary assessment on the quality of rheum palmatum herbs or medicinal slices with different producing areas, different batches and different growth years.

Description

technical field [0001] This application relates to a method for evaluating the quality of traditional Chinese medicines with multi-component comprehensive quantification. Background technique [0002] Quality evaluation of traditional Chinese medicine has always been a hot and difficult point in the research and production of traditional Chinese medicine, and it is also an important basis and key to the modernization of traditional Chinese medicine. At present, the quality evaluation of traditional Chinese medicine mostly refers to the mode of phytochemistry and western medicine quality evaluation, and the quality of medicinal materials is evaluated by single determination of the content of certain chemical components in medicinal materials. From the perspective of traditional Chinese medicine, the control of a single component is difficult to truly reflect the efficacy of traditional Chinese medicine, especially for compound preparations. The detection of any index componen...
