| Abstract: | A method of supercritical CO 2 extraction was used to extract the flavanoides and gingkolides from the leaves of gingko,and the optimum operations were discussed. The results show that this technology is efficient to extract the medicinal active materials from the leaves of gingko under the lower operation pressure,the content of the flavanoides in the product is above 28% and that of the gingkolides is above 7%.At the same time,the harmful component in gingko is reduced efficiently. |
