AI Technical Summary

Problems solved by technology

The disclosed extraction methods of Angelica and Chuanxiong include ether extraction, ether extraction after ethanol leakage and supercritical extraction, etc. Ether extraction requires a large amount of organic solvents, which is easy to cause environmental pollution, and the operation is easy to be dangerous. The extraction yield of the oily components contained in the two medicines is relatively high, but special equipment is required, and it is not conducive to the extraction of water-soluble active components in the two medicines. Therefore, it is difficult to popularize and apply, and it is not conducive to large-scale production.
