| Abstract: | Microwave assisted enzymic method was adopted to extract total flavonoids (TF) in the leaves of Rosa davurica. The extraction efficiency of TF was used as examination indicator, while the extraction technology was optimized and determined. The concentration of the ethanol extraction solvent, the ratio between raw material and solvent, the complex enzyme ratio between cellulase and pectase, the temperature, time and times of enzymolysis, the pH value of enzymolysis, the power of microwave generator, extracting time, temperature and extraction times were 75%, 1∶25, 2∶1, 55℃, 120 min, 2 times, 4.5, 600 W, 15 min, 60℃, and 2 times, respectively. The average extraction efficiency of TF was 32.21 mg·g-1 under the optimized extraction conditions, which showed that enzymes method was suitable for extracting TF in the leaves of R. davurica. |
