| titleOfInvention | A kind of method measuring multi-form content of phytosterol in Caulis Sacchari sinensis |
| abstract | The invention discloses a kind of method measuring multi-form content of phytosterol in Caulis Sacchari sinensis; plant sterol in Caulis Sacchari sinensis sample is carried out after acid hydrolysis and alkali formula saponification by the method; by ester state sterol, join saccharide sterol and acyl group is joined saccharide sterol and is converted into free state plant sterol; extract and coordinate existing plant sterol extracting method to obtain the extract containing corresponding free state sterol respectively; obtain the content of said extracted thing by high-efficient liquid phase chromatogram technology, and be calculated the content of multi-form plant sterol in Caulis Sacchari sinensis sample.The inventive method selects the soda acid combining form of ethanol solution hydrochloride and potassium hydroxide-ethanol solution, determine suitable reaction condition, select 6 ketone Dihydrocholesterols as internal standard, ether is as extractant, and coordinate the high-efficient liquid phase chromatogram condition of optimization, significantly improve extraction efficiency and the accuracy of detection. |
