Quality detection method of sophora japonica branch medicinal material

Abstract

The invention belongs to the technical field of quality control of medicinal materials, and particularly relates to a quality detection method of a sophora japonica branch medicinal material, the sophora japonica branch medicinal material comprises Chinese scholartree dry branches, robinia pseudoacacia dry branches, Chinese scholartree fresh branches and robinia pseudoacacia fresh branches; the quality detection method comprises the steps of character identification, microscopic identification and thin-layer identification of medicinal materials, and determination of moisture content and extract content of dry branches. The method has the advantages of being scientific, reasonable, high in accuracy, high in stability, low in identification cost and short in identification time.

Description

technical field [0001] The invention belongs to the technical field of medicinal material quality control, and in particular relates to a quality detection method of Sophora japonica medicinal material. Background technique [0002] Sophora japonica L. and Robinia pseudoacacia L. are the fresh or dry branches of leguminous plants Sophora japonica L. and Robinia pseudoacacia L. Harvest in four seasons, remove leaves, sun-dried or used fresh.

Problems solved by technology

However, this method is mainly aimed at the national locust tree, and it is impossible to specifically identify the national locust tree and Robinia pseudoacacia, and there are few identification schemes for other locust branches, which directly caused confusion about the national locust tree dry branches, Robinia pseudoacacia dry branches, national locust tree fresh branches, and Robinia pseudoacacia fresh branches. The gap in identification and differentiation technology leads to low identification accuracy of medicinal materials, which affects the practical effect and promotion

[0006] At present, there are few quality control methods about Sophora twigs in the prior art, and the evaluation index is single and inaccurate, and usually the amount of dry branches of Sophora twigs is 10-20g, while that of fresh branches is doubled. These factors have directly affected the law of medication. and effect, so quality control and effective identification of Sophora japonica is essential
