| titleOfInvention | Method for extracting flavones in Chinese herbal medicine by surfactant cooperated supersonic wave-enzymatic hydrolysis |
| abstract | The invention discloses a method for extracting flavones in Chinese herbal medicine by surfactant cooperated supersonic wave-enzymatic hydrolysis, which comprises the following steps: 1) uniformly mixing a Chinese herbal medicine, an enzyme preparation, glucose and deionized water and placing in an ultrasonic apparatus, setting the ultrasonic temperature, power and frequency, carrying out enzymatic hydrolysis for a while; 2) adding a surfactant with certain concentration in a liquid solid mixture obtained in the step 1) for ultrasonic extraction; 3) cooling the obtained products from the step 2) to the room temperature, carrying out vacuum filtration to obtain the filtrate which is an extract containing the flavones. The operation method and the external environment of the invention the invention has no high requirements on the operation method and the external enviroments. The surfactant is capable of reducing the tension force of the interface and possessing the solubilization effect, the enzyme preparation possesses the wall breaking effect; the supersonic wave possesses the characteristics of mechanical oscillation and cavitation effect, the extraction time can be shortened, the solvent can be saved, the influence of high temperature on the extracted component can be minimized. According to the invention, the advantages of the extraction method are integrated, the flavones yield in the Chinese herbal medicine is high and the inoxidizability is good. |
