The Ginkgo flavones were extracted from water leaching liquor of the Ginkgo leaves. The leaching conditions, extractant, extraction time, temperature, pH of the extraction solution and phase separation have been investigated. The optimum extraction conditions are:60℃, 30 min. pH=3~4 and with ethylbutyl ketone as extractant.
- Ginkgo leaf,
- flavone,
- extraction
