| Abstract: | Using mulberry (Morus alba L.) leaves as raw material, adopting an enzymatic extraction method to study a new production process of rutin.Extraction yield of rutin was taken as the evaluation index, optimization range of the enzymatic extraction process parameters were selected using single factor methodology, then those best conditions were optimized using response surface methodology. Experiment results showed that when the enzymatic hydrolysis temperature was 30℃, the concentration of enzyme was 0.5mg/mL, the pH value was 3.0, and the enzymatic treatment time was 7h, the optimum extraction rate of rutin from mulberry leaves was 0.786mg/g, which was 60.5％ higher than that in traditional alcohol extraction method. |
