| titleOfInvention | A kind of preparation method of the O β D glucopyranoside reference substances of Cassia ketone 8 |
| abstract | The invention provides a kind of O of Cassia ketone 8 β The preparation method of D glucopyranoside reference substances, comprises the following steps：（1）The extraction of Rhizoma Polygoni Cuspidati；（2）Large pore resin absorption column chromatographic isolation；（3）Decolorizing resin post separation；（4）Preparative high-performance liquid chromatographic separates to obtain the O of Cassia ketone 8 β D glucopyranoside reference substances.High performance liquid chromatography purity test, different chromatographic columns and different eluent gradient elution requirement measurement results show to be a mass-tone spectral peak；It is more than 98% with areas of peak normalization method and the principal component Self-control method quality measurement fraction for being not added with correction factor, meets the requirement of assay traditional Chinese chemical contrast.Reproducible and the inventive method separation cycle is short, yield is high, and cost is low. |
