Research Progress on the New Extractive Techniques for the Effective Components of Chinese Medicine

The extraction of effective components from Chinese medicine is the key link in pharmaceutical process, and the choice of extractive technique affects the officinal quality. With the development of science and technology, the extractive techniques are changing quickly. This paper summarized the common extractive techniques for the effective components of Chinese medicine, which include supercritical fluid extraction, ultrasonic extraction technology, enzyme extraction technology, molecular imprinting extraction technology, microwave extraction technique and inner ebullition extraction technology, and introduced the characteristics, the theories of these techniques and their research progress.
