Helicid extraction process

The invention relates to the technical field of medicine production, in particular to a helicid extraction process, which specifically comprises the following steps: crushing tofu fruits, removing impurities from the tofu fruits, crushing the tofu fruits into coarse grains of 4-6mm by using a coarse powder machine, wrapping fine powder by using gauze, putting the wrapped fine powder into an extraction tank, and extracting for 2-3 hours; and extracting for 2-4 times by using a hot water soaking solution, and sequentially adding alkali, adding acid, concentrating under reduced pressure and crystallizing and refining to obtain a refined product. A water extraction method is adopted, the extraction rate is higher than 50%, the cost is low, a positive promotion effect on development of pharmaceutical economy is achieved, and compared with ethanol extraction in the prior art, water extraction is low in cost, easy to obtain, capable of saving cost and reducing loss and environmentally friendly. 本发明涉及药品生产技术领域，具体为一种豆腐
