Plant extracts have become an important source of biologically active compounds for many drug discovery programs, and several important drugs have been isolated and identified from plants. In any separation procedure where the final product is a drug or lead compound, some type of bioassay screening or pharmacological evaluation must be used to guide the separation process to obtain pure biologically active ingredients.
The choice of the bioassay to be used usually depends on the target syndrome and the available information about the plant to be studied. For example, if a plant has a history of ethanol pharmacology for a specific disease, then people will rationally use a specific bioassay technique that can predict a well-known therapeutic activity to isolate the lead that causes that biological activity.
Our company has complete plant extraction technology and related laboratories. As a century-old pharmaceutical company, we have produced many products on a large scale:
