Abstract

The invention relates to a detection method of folium artemisiae argyi charcoal. The folium artemisiae argyi charcoal is prepared by taking dry leaves of compositae plant folium artemisiae argyi as a raw material, processing by a charcoal calcining method, calcining thoroughly, storing properties, and cooling. Artemisia argyi contains more aromatic components, but in order to achieve the purpose of calcined charcoal storage, the argy wormwood leaf charcoal retains the aromatic components; according to the method, the quality of the folium artemisiae argyi charcoal with calcined charcoal retention is detected by adopting the thin-layer chromatography, the detection cost is low, operation and color development are convenient, spots are concentrated, qualitative analysis results are visual, characteristic spots in the folium artemisiae argyi charcoal can be accurately judged, and the quality of the folium artemisiae argyi charcoal used for preparing smokeless moxibustion stick products is further guaranteed.

Description

[0001] This application is a divisional application with the patent application number "201810490761.8", the application date is "May 21, 2018", and the invention title is "A Mugwort charcoal and its preparation method and detection method". technical field [0002] The invention relates to a method for detecting mugwort charcoal.
