Problems solved by technology

This identification method belongs to the physical identification method, and it can only identify the asparagus from the microcosm. Using this method to identify the authenticity of asparagus is easy to be confused with other medicinal materials such as counterfeit asparagus fern. That is to say, the identification method The specificity is not strong

Abstract

The invention discloses a thin-layer chromatography identification method of a radix asparagi decoction piece in an ophiopogon and asparagus decoction composition. The identification method is established by utilizing a thin-layer chromatography test method and adopting a lower-layer solution of trichloromethane-methyl alcohol-water as a developing solvent after the radix asparagi decoction piececomponent in ophiopogon and asparagus decoction, a radix asparagi contrast medicinal material, protodioscin and a protodioscin contrast product are mixed. The identification method is high in accuracyrate, high in specificity and wide in using range.

Description

technical field [0001] The invention belongs to the technical field of identification of traditional Chinese medicinal materials, and in particular relates to a thin-layer chromatographic identification method for asparagus decoction pieces in Erdong decoction prescription.
