| Abstract: | Some solvent systems for extracting flavone from gingko (Ginkgo bibola) leaves were studied, i. e. ethanol, NaOH ethanol solution, NaOH water solution and Na 2CO 3 water solution. NaOH water solution gave the best results, followed by NaOH ethanol solution. Compared with extraction with ethanol, the greatest extraction rate of flavone increased by 28.4% and 46.5% and the extraction time was reduced by 0.5 and 1 h in the treatments of 0.25% NaOH ethanol solution and 0.1% NaOH water solution, respectively. |
