Method for identifying cordyceps sinensis through microscopic staining

Abstract

The invention belongs to the field of crude medicine identification, and particularly relates to a method for identifying cordyceps sinensis through microscopic staining. The invention aims to solve the technical problem that the authenticity of the cordyceps sinensis powder which is circulated and sold in the market is difficult to identify. The technical scheme for solving the problem is to provide the method for accurately identifying the cordyceps sinensis powder. The method comprises the following steps that: the cordyceps sinensis powder to be inspected is taken, stained and produced into a smear; and the produced smear is subjected to microscopic observation under a microscope, if the special structure of the cordyceps sinensis of each smear can be clearly observed, the obvious blue spots under the iodine staining are not existed, and the obvious plant tissues are not observed, the cordyceps sinensis powder can be identified to be pure, otherwise, the cordyceps sinensis powder is not pure. The method can clearly identify the fine medicinal slice powder and the matter which does not belong to the cordyceps sinensis, is low in cost, has high efficiency, is not easy to be disturbed by various addition ingredients, and has very high accuracy and a good application prospect in the field.

Problems solved by technology

[0004] The pure Cordyceps sinensis powder that is currently circulated and sold in the market is made into a certain dosage form, so it is difficult to distinguish the authenticity from the fake, although the means of testing equipment can be used to prove the existence of some markers of Cordyceps sinensis, such as the content of cordycepin and adenosine , but these markers are easy to buy, and they are not expensive, and they can be used as additives in theory, so physical and chemical tests can neither detect impurities nor distinguish fakes
