Specific applications can be divided into the following areas:

1. Extraction of bioactive molecules from medicinal plants, extraction and separation of alkaloids;

2. Lipids from different microorganisms, or for lipid recovery, or removal of lipid lipids from glycoside and protein;

3, from a variety of plants in the extraction of anti-cancer substances, especially from the bark and leaves of Taxus chinensis obtained taxol to prevent cancer;

4, vitamins, mainly vitamin E extraction;

5. Purification of various active substances (natural or synthetic) to remove unwanted molecules (such as pesticides from vegetable extracts) or "dregs" to obtain purified products;

6. Processing of various antibacterial or antioxidant extracts, such as basil, string red, thyme, garlic, onion, chamomile, chili powder, licorice and fennel seeds.
