| Abstract: | The extraction conditions of antioxidative substances from Du-zhong(Eucommia ulmoides Oliv.) leaves assisted by ultrasonic were studied by single factor experiment.Total antioxidant capacity(TAC) was used as the activity monitoring parameter.The optimized extraction conditions were as follows: Du-zhong(Eucommia ulmoides Oliv.) was extracted twice with 20%(volume fraction) ethanol-water solution for 40 min each time,the ratio of mass of raw material to volume of extraction solvent was 1:18. |
