Research on Identification of Bombyx Batryticatus and Adulterants
In order to explored the identification method between Bombyx Batryticatus and Adulterants.In this study the characters of Bom-byx Batryticatus and adulterants were described by morphology,texture,sction and odor of samples.The difference between Bombyx Ba-tryticatus and adulterants was compared by optical microscopy for the white powder frost on the surface of Bombyx Batryticatus.The dif-ference between Bombyx Batryticatus and Adulterants was compared by the reaction of dilute hydrochloric acid with white powder frosting on the surface of Bombyx Batryticatus.Using silica gel G as stationary phase and petroleum ether(60～90 ℃)-acetone(7∶3)as developing agent,thin layer chromatography was used to identify the methanol extracts of Bombyx Batryticatus and Adulterants.Compared with Bom-byx Batryticatus,the adulterants are divided into 3 categories throngh character identification.Starch granules were detected in some adul-terated products by optical microscopy.Some white powder frosts on the surface of some adulterated products show positive reaction of carbonate or bicarbonate.By TLC identification,the TLC characteristics of some adulterated products are obviously different.The method is fast,easy to operate and specific.It can provide reference for improving the identification method of Bombyx Batryticatus.
