[0004] Gentiana is a root medicinal material, which must be processed into decoction pieces before it can be used as medicine. The purpose of cutting into decoction pieces is to facilitate the decoction of active ingredients and give full play to the efficacy of the medicine. If the processing is not done properly, the effective ingredients will be lost, and the efficacy of the medicine will be greatly reduced.

[0073] Preparation of the control solution: Take appropriate amount of gentiopicroside reference substance and loganinic acid reference substance, weigh them accurately, add methanol to prepare solutions containing 0.5 mg of gentiopicroside and 0.3 mg of loganinic acid per 1 ml, namely have to.
[0074] Preparation of the test solution: Get about 0.5 g of the powder of this product (passed through a No. 3 sieve), accurately weighed, put in a stoppered Erlenmeyer flask, add 20 ml of methanol precisely, and ultrasonically treat (power 500W, frequency 40kHz) for 30 minutes. Let it cool, then weigh it, make up the lost weight with methanol, shake well, filter, and take the filtrate to obtain the final product.
[0075] Determination method: Precisely draw 5-10 μl each of the two reference substance solutions and the test solution, inject it into the liquid chromatograph, measure it, and obtain it.
[0076] Calculated as a dry product, this product contains no less than 2.5% of th...

Abstract
The application belongs to the technical field of Chinese medicinal materials processing, and particularly relates to a screening method for preparation process of gentiana macrophylla. The gentiana macrophylla is a root medicinal material, which must be processed into pieces during the use. The purpose of cutting into pieces is to facilitate the frying of active ingredients and to fully exert theeffect. However, since the glycosides in the gentiana macrophylla have its particularity, if improperly processed, the glycosides are hydrolyzed, the components are lost, the cross section of the traits turns green, and the pesticide effect is greatly reduced. The application provides a screening method for preparation process of gentiana straminea, comprising the following steps: 1) determiningthe components to be determined and the determination method according to the preparation process of the gentiana macrophylla; 2) designing the orthogonal test and using different preparation processes to obtain a product, measuring the product, and measuring the content of the component to be determined in the product; and 3) screening the optimal preparation process of the gentiana macrophylla according to the measurement result in the step 2). The method can determine the preparation conditions and parameters of gentiana macrophylla, establish the operating instruction of the preparation process, and improve the quality of medicinal slices of gentiana macrophylla.
Description
technical field [0001] The application belongs to the technical field of processing traditional Chinese medicinal materials, and in particular relates to a screening method for the preparation process of Gentiana chinensis. Background technique [0002] Traditional Chinese medicine is a medical science that has been gradually formed and continuously enriched and developed by the people of all ethnic groups in our country during thousands of years of preparation, life practice and struggle against diseases. It is a treasure of the Chinese nation. The preparation of traditional Chinese medicine is a pharmaceutical technology adopted according to the theory of traditional Chinese medicine, according to the needs of syndrome differentiation and treatment, the nature of the medicine itself, and the different requirements of dispensing and preparation. It is a precious intangible cultural heritage unique to our country. The preparation of traditional Chinese medicine can reduce o...
