Abstract

The invention discloses a thin-layer chromatography identification method for ant lions. The method comprises the following steps that: firstly, investigating the applicability of a sample, measuringthe total nitrogen contents of the ant lions, and carrying out the thin-layer chromatography identification of the cholesterol and the amino acid of the ant lions. The thin-layer chromatography identification method for ant lions has the advantages of convenience in operation, simple equipment, easiness in color development and high expansion speed, and the identification method for the ant lionsis normalized.

Description

technical field [0001] The invention relates to the technical field of identification of traditional Chinese medicine, in particular to a method for identifying sand cattle by thin-layer chromatography. Background technique [0002] The source of the sand cow in the "Standard List of Chinese Medicinal Materials" is the antlion, an antlion Myrme Leon formicarius L . , East China Antfly EuroLon sinicus (Navas) . or yellow-footed antfly Hagenomyia micans (MacLaehLan) dried larvae. Caught in autumn, scalded to death with boiling water, and dried.
