| titleOfInvention | Method for simultaneously extracting 4 isoflavone compounds from radix puerariae |
| abstract | The invention discloses a method for simultaneously extracting 4 isoflavone compounds from kudzuvine root, wherein the 4 isoflavone compounds which are simultaneously extracted are respectively as follows: puerarin, 3-methoxy puerarin, daidzin and daidzein; the extraction method comprises the following steps: 1) pulverizing cleaned and dried radix Puerariae, and sieving to obtain radix Puerariae powder with particle size larger than 109 meshes; 2) mixing the kudzu vine root powder with water according to the mass ratio of 1:16-18, and carrying out high-temperature reaction at the temperature of 118-; 3) and after the reaction is finished, extracting the solution after the reaction, taking supernate, filtering and detecting. The method can simultaneously improve the extraction rate of four isoflavone substances, i.e. puerarin, 3-methoxy puerarin, daidzin and daidzein, and can simultaneously obtain the optimal extraction rate. |
