Embodiment Construction

[0080] Below by embodiment the present invention will be further described.

[0081] A detection method for evaluating the quality of Huobahua root medicinal material, comprising the steps of:

[0082] The first step: observe the product properties: mainly observe the shape, the shape is required to be irregular block, flake or segment; the overall shape color is required to be brownish yellow to brown on the surface; the soft and hard texture is required to be hard and not easy to break; The cross-section is light brown or light yellow, smell and taste; through the above method, it can be preliminarily judged whether the medicinal material is torch flower root, if all are satisfied, go to the next step.

[0083] Step 2: After screening in Step 1, take the peeled and dried torch root for later use;

[0084] The third step: powder microscopic identification: take the torch root of step two, grind it into powder, take a small amount and put it under a microscope to observe whet...

Abstract

The invention discloses a detection method for evaluating the quality of a colquhounia root medicinal material. The detection method comprises the following steps: 1) taking peeled dry colquhounia roots for later use; 2) performing powder microscopic identification; 3) determining the nature of epicatechin by using a thin-layer chromatography test method; 4) checking the moisture, the total ash content and the acid-insoluble ash content, and determining a water-soluble extract; 5) determining the epicatechin content and the triptolide content of the colquhounia roots. According to the method,through the following steps: preliminarily screening out raw materials through character observation; performing microscopic identification by powder, and observing the microscopic characteristics ofthe colquhounia roots; then checking the moisture, the total ash content and the acid-insoluble ash content; performing primary determination of impurity content; extracting the medicinal materials, measuring the extract, preliminarily determining the extractability of the effective components of the medicinal materials, and accurately quantifying the conditions of the main components of epicatechin and triptolide by high performance liquid chromatography, thereby comprehensively judging the quality of the colquhounia roots. The method is beneficial to prejudging the clinical medication risk and ensuring the safety and effectiveness of clinical medication.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a detection method for evaluating the quality of torch flower root medicinal materials. Background technique [0002] The torch flower root is derived from Tripterygium hypoglaucum (Lev.) Hutch, a plant of the Euonymus family, dried and peeled roots, bitter, warm, and poisonous. Its active ingredients are alkaloids, terpenes, lactones, phenolic acids, etc. It has the effects of expelling wind and dampness, relaxing tendons and activating collaterals, clearing away heat and detoxification, and has obvious inhibitory pathological immune response and anti-inflammatory and analgesic effects. [0003] As we all know, medicinal effects are closely related to medicinal materials. "Huobahuagen Tablets" is a product of our company. The main effects of this medicine are to expel wind and dampness, relax muscles and activate collaterals, clear away heat and detoxify. ...
