Extraction process and antioxidant activity of iridoids from Morinda officinalis
摘要
Abstract
To improve the total iridoids of Morinda officinalis from Shaoguan Wengyuan,the single test and Box-Behnken response surface method were designed by cellulase-assisted ultrasonic extraction,and the antioxidant activity in vitro was investigated.The results showed that the optimal extraction process conditions of total iridoids from Morinda officinalis with enzyme-assisted ultrasonic were:enzyme amount of 2％,enzyme digestion time of 2 h,liquid-to-feed ratio of 33∶1(mL/g),ultrasonic time of 46 min,and ethanol concentration of 39％.Under the condition,the yield of total iridoids was 30.86％,and the relative error to the predicted value was 0.16％.In addition,the total iridoids of Morinda officinalis showed certain antioxidant activity,with an IC50 of 5.582 mg/mL for scavenging superoxide anion radicals and a good reducing ability for ammonium molybdate.关键词
