| Abstract: | A new method for microwave assisted extraction of food stain from Begonia Fimbristipula Hance were studied. The optimal extraction conditions were obtained as follows: the dosage of dry flower powder is 2 g, the extracting solvent is 60% alcohol (volume percent) , the ratio of solvent to powder is 60 g/mL, microwave power is 648 W, extraction time is 200 s and repeat once again. Under these optimal conditions, the extraction rate is 96. 8 %, the productive rate is 9. 98%, the colority (1%,526 nm) and pH value of the extractive are 10. 5 and 6. 5 respectively. |
