Abstract

The invention belongs to the medicinal material identifying field and in particular relates to a method for identifying cordyceps sinensis powder through microscopic dyeing. The invention aims to solve the technical problem that the sold pure cordyceps sinensis powder in market is difficult to identify. The technical scheme of the invention used for solving the problem is to provide a method for accurately identifying cordyceps sinensis powder. The method comprises the following steps: taking cordyceps sinensis powder to be detected, dying to prepare smears; placing the prepared smears under a microscope for microscopic observation, and if the special structure of cordyceps sinensis can be clearly observed on each smear without obvious blue spots caused by iodine staining and no obvious plant issue can be observed, judging that the sample is pure cordyceps sinensis powder; and if not, judging that the sample is not pure cordyceps sinensis powder. The method of the invention can be used to clearly identify fine cordyceps sinensis powder prepared for decoction and substances not belonging to cordyceps sinensis, the cost is low, the efficiency is high, method can be not easily interfered by various additives, the accuracy is very high, and the method has good application prospects in the medicinal material identifying field.
