Methods for extracting and measuring content of betulinic acid and polysaccharide in rhizoma nelumbinis |
| abstract |
The invention relates to methods for extracting and measuring content of betulinic acid and polysaccharide in rhizoma nelumbinis. A response surface analysis method of a Box-BehnkenDesignS (BBD) central composite design model is adopted, three change factors, three levels and a small amount of experimental groups are used for optimization to acquire an optimal extraction method of betulinic acid and polysaccharide in rhizoma nelumbinis, and optimal yield is realized. By the extraction method acquired preferentially, efficiency is improved while energy consumption and pollutant emission can be lowered; the extraction method is of actual significance in industrialized production. The content measuring method screened out through a lot of experiments is simple in operation, high in practicability and capable of providing a scientific basis for efficient utilization of betulinic acid and polysaccharide. |
