| Abstract: | Ginkgo Biloba L.was extracted by SF-CO 2 with and without ethanol as entrainer.G.B.L.flavonoids in extracts and residue leaf were analysed with HPLC.Flavonoids were not extracted by SF-CO 2 with and without entrainer,while flavones were extracted by SF-CO 2 with entrainer. G.B.L.Flavonoids extracted from residue leaf by solvent were found to have been concentrated compared with that from the original leaf. |
