| Abstract: | Taking the total extraction ratio of lavonoids in ginger as a target, by using the single factor method, the influence of the solid to solvent rate, solvent concentration and extraction temperature on the total extraction ratio of lavonoids in ginger is studied. The quadratic orthogonai regression design is employed to built the equation and to optimize the extraction technique. The optimized condition is as follows： the solid to solvent rate is 1 ： 40, the concentration is 0.77, and the temperature is 67 degree. Meanwhile the established equation can well predict and optimize the extraction rate of flavnoids in ginger. |
