[0031] 【Source】This product is the dry leaf of Artemisia argyi Levl. et Vant. Pick in summer when the flowers are not in bloom, remove impurities and dry in the sun.
[0032] [Processing] Take Artemisia argyi leaves, remove impurities and stalks, sieve off debris, put them in a calciner according to the method of calcining charcoal (General Rule 0213 of the Fourth Part of the Pharmacopoeia of the People's Republic of China, 2015 Edition), seal it, heat it until it is calcined, and store it. Cool and take out.
[0033] 【Properties】This product is layered, black and shiny, easily broken, and smokeless when burned.
[0034] [Check] The acid-insoluble ash content must not exceed 14.0% (General Rule 2302 of "The Pharmacopoeia of the People's Republic of China 2015 Edition Fourth Part": Take mugwort leaf charcoal powder, make it pass through the No. In a crucible with constant we...
Embodiment 2
[0042] Embodiment 2 The thin-layer chromatography detection method of mugwort charcoal of the present invention
[0043] Take 5 g of mugwort leaf charcoal powder, add 50 ml of ether, sonicate for 30 minutes (keep the water temperature below 30 ° C), filter, evaporate the filtrate to dryness, add 1 ml of ethyl acetate to dissolve the residue, and use it as the test solution. Test according to thin-layer chromatography (general rules 0502), draw 10 μl of the above solution, spot on the silica gel G thin-layer plate, use n-hexane-ethyl acetate (9:1) as the developer, develop, take out, dry in the air, and use 10 The % sulfuric acid ethanol solution is used as a chromogenic agent, and after heating at 105°C, inspect it under an ultraviolet lamp (365nm). In the chromatogram of the test product, there are fluorescent spots with Rf values of about 0.22, 0.31, 0.45, 0.66, 0.70, and 0.74, respectively.
