How To Extract Ginsenoside From Ginseng?

Because ginsenosides have special pharmacological effects, it is an essential and long-term research work to improve the extraction process of Ginseng Extract Powder and improve the extraction efficiency of ginsenosides.

How Is Ginseng Extract Made?

At present, the general extraction methods of ginsenosides include water extraction, organic solvent extraction, percolation, distillation, ultrasonic extraction and supercritical fluid extraction.

The extraction of ginsenoside monomers generally goes through four processes:

Selection of raw materials → extraction of ginsenosides → separation and purification → preparation

In general, ginseng stems and leaves are screened for alcohol body, and the extract is separated and purified through extraction, vacuum concentration, high-speed centrifugal separation and other processes.

The traditional extraction method has low equipment cost and simple operation, but has long extraction time and low extraction efficiency. A large number of chemical reagents can easily cause environmental pollution. Some thermally unstable components and volatile components in the heating extraction method are easily destroyed and lost, resulting in an incomplete variety of active components in the extract.

With the development of the modernization of traditional Chinese medicine, the optimization and improvement of modern separation and purification processes such as biological enzyme extraction, microwave ultrasonic-assisted extraction, and supercritical fluid extraction, ginsenosides have been significantly improved in terms of extraction efficiency and types of extracts.

Ultimately, an environmentally friendly, safe and efficient extraction process will better promote the further development and utilization of ginsenosides, which provides a reference for the further research of ginsenosides and the types of ginsenoside products.
