Embodiment
[0054] The quality detection method of Xiaoer Huatan Zhike Granules comprises the following steps:
[0055] (1) Identification of Morus alba:
[0056] Weigh 5g of the fine powder of this product, add 20ml of ethyl acetate, stir in a water bath at 50-60°C for 1 minute, filter, evaporate the filtrate to dryness, add 0.5ml of ethyl acetate to dissolve, and use it as the test solution. Take another 0.3g of Cortex Mori reference medicinal material, add 2ml of ethyl acetate, stir in a water bath at 50-60°C for 1 minute, let stand, and the supernatant liquid is the reference medicinal material solution. Take 15-20 μl of each of the above solutions, spot on the same silica gel G thin-layer plate, use petroleum ether-ethyl acetate-acetone-formic acid = 4:2:2:0.1 as the developer, develop, take out, dry in the air, and use ultraviolet light View under 365nm light. In the chromatogram of the test product, fluorescent spots of the same color appear at the positions corresponding to th...
