Embodiment 1
[0022] Embodiment 1 The preparation of Periplaneta americana ethanol extract of the present invention
[0023] Coarsely crush the dried Periplaneta americana, add 4000g of water to every 1000g of coarse powder, soak for 1 hour, the temperature is about 70 ℃, extract three times, the first time is 8 hours; the second time add water 3000g, extract for 6 hours; the third time Add 3000g of water and extract for 4 hours. Combine the three extracts, filter, and concentrate the filtrate to a relative density of 1.10-1.20 (70°C), add 95% ethanol, keep stirring at 70°C for 30 minutes, let stand for 12 hours, discard the upper layer of grease, filter the lower layer of liquid medicine, Recover ethanol from the filtrate, concentrate under reduced pressure to a relative density of 1.20-1.25 (70°C), add 500ml of glycerin, stir well, filter, and dilute to 10000ml with purified water to obtain the product.
