Compared with extraction methods such as solvent, ultrasonic, microwave and even enzymolysis, the supercritical fluid extraction method has better selectivity for ginkgolic acid in extracted solutes. In addition, the supercritical fluid extraction method has the advantages of high extraction efficiency, mild conditions, uneasy destruction of active ingredients of the extracted substances, and the like, so that the supercritical fluid extraction method is increasingly widely applied to the field of extracting the active ingredients of the Chinese herbal medicines. However, since the existing quality standard prescribes that the content of ginkgolic acid in foods, medicines and the like is less than 10 mug/g, the supercritical fluid extraction process not only can realize the efficient recovery of ginkgolic acid in ginkgo leaves preferentially, but also has very important influence on the continuous extraction and purification of flavonoid and terpene lactone active substances in the residual materials after the extraction of ginkgolic acid. Finally, most of ginkgo leaves are directly sold but not developed and utilized more because of the existing means for picking ginkgo leaves, processing technology and the lag of industrial production, and the economic value of the ginkgo leaves is not fully exerted.
In the prior art, patent application CN201410413123 discloses a method for removing and enriching ginkgolic acid from ginkgo leaf extract.

Patent application CN201510984822.2 discloses a method for supercritical fluid extraction of ginkgolic acid, which adopts supercritical carbon dioxide fluid extraction deacidification process to extract ginkgolic acid from untreated folium Ginkgo extract. However, this patent application does not disclose relevant supercritical equipment suitable for production, nor does it provide information about the subsequent extraction of ginkgo leaf extract.
Patent 201820336352.8 provides a device for removing ginkgolic acids from ginkgo leaves by combining supercritical carbon dioxide extraction and rectification technologies. However, the purpose of the patent is to remove ginkgolic acid from ginkgo leaves, thereby improving the yield and purity of flavonoid extract, and large-scale continuous recovery and purification of ginkgolic acid from ginkgo leaves are not realized, so that a carbon dioxide gas adsorption device is designed to solve the problems.
