Multi-medicinal fast thin-layer identification method and containing device for reference materials of rehmannia and lycium root-bark decoc

Abstract

An embodiment of the invention discloses a multi-medicinal fast thin-layer identification method and a containing device for reference materials of rehmannia and lycium root-bark decoc, and the identification method comprises the following steps of preparation of a control medicinal solution, preparation of two test solutions, and chromatographic detection and comparison of the test solutions andcorresponding control medicinal solution. The containing device comprises a cooling tank, a containing tank provided inside the cooling tank and used for containing the reference materials of rehmannia and lycium root-bark decoc, and a stirring structure rotatably provided inside the containing tank. In the invention, the adopted preparation method of two test solutions is simple and fast, and requires fewer pre-processing steps; at the same time, in the identification of five medicinal materials, the solvents in the test solutions and the reference medicinal solution only involve methanol orwater, so that the cost of the entire preparation method is effectively reduced, and the detection efficiency is greatly improved; compared with a conventional thin-film identification corresponding to a traditional medicinal material, the material is classified in the invention to further reduce the number of times of thin-layer identification, thereby realizing a new model of one test and multiple evaluations, and better improving the identification efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of qualitative detection of traditional Chinese medicines, and in particular to a multi-flavor rapid thin-layer identification method and a container device for reference substances of Liangditang. Background technique [0002] Liangdi Decoction comes from the book "Fu Qingzhu Gynecology" written by Fu Shan (word Qingzhu) in the late Ming and early Qing Dynasties. It is a classic prescription published by the State Administration of Traditional Chinese Medicine. It is composed of six herbs, Ophiopogon japonicus, Digupi, and donkey-hide gelatin. It is widely used in clinical practice and is a commonly used prescription for gynecology. The prescription ratio and preparation process are as follows: Prescription: wine rehmannia (one tael), scrophulariaceae (one tael), wine peony (five coins), Ophiopogon japonicus (five coins), Digupi (three coins), donkey-hide gelatin (three coins) mon...

AI Technical Summary

Problems solved by technology

[0004] The low identification rate means that there may be multi-flavored medicinal materials in the preparation that cannot be identified as ingredients, and the traceability of the ingredients can not be guaranteed, so that the product quality cannot be guaranteed; even for varieties with a high rate of TLC identification, there are many It is necessary to prepare the corresponding test solution for each identification item, and use different expansion systems

At the same time, in order to eliminate the interference of impurities, the pretreatment steps of the sample are more cumbersome, the solvent consumption is large, and the detection cycle is long.
