Embodiment 1
[0031] A preparation method of Shedan Chuanbei Capsules comprises the steps of:
[0032] Step 1, prepare Fritillaria sichuan fine powder, Fritillaria sichuan concentrate and snake bile;
[0033] The preparation method of the fritillary fritillary concentrate is as follows: extract fritillary fritillaria with 70% ethanol for 2-4 times, then extract it with water for 2-4 times, combine the liquid extracts to obtain the concentrated liquid by vacuum, add 0.3% sorbic acid , to obtain Chuan Fritillaria concentrate.
[0034] The preparation method of the Fritillaria fine powder is as follows: take the Fritillaria coarse powder obtained after the Fritillaria powder is percolated and extracted with 70% ethanol, dry by microwave, pulverize and sieve the Fritillaria fine powder.
[0035] The preparation method of the snake bile is as follows: separate the snake gall and remove the bile coat to collect the bile → autoclaving / 115°C for 30 minutes → bile + soaking wine → snake bile
