ABSTRACT
  The active ingredient of ginkgo biloba is the object that people always  focus on research. The traditional extraction process is solvent and water extraction. With the continuous development of science and technology, many new methods such as supercritical fluid method, resin adsorption method, microwave extraction method, ultrasonic extraction method and high-speed countercurrent chromatography continue to develop and application, more and more methods are found and used for extraction Ginkgo biloba in the active ingredient. For people to study the active ingredients of Ginkgo biloba provides more ways. In this paper, the extraction technology and progress of active ingredients in Ginkgo biloba leaves were reviewed.
