Abstract:The ultrasonic-assisted extraction of tannin acid in Chinese Gall was studied. According to the quadratic orthogonal regression,the results showed that the optimized extraction conditions were as follows:the ratio of solvent to solid was 37.1∶1(m/m),the extraction time was 57 min,the extraction temperature was 27.4℃,the ultrasonic power was 842 W. Under the optimized techniques,the extraction ratio of tannin acid was up to 93.5%. |
