| titleOfInvention | The preparation method of Penta-O-galloyl-D-glucopyranose chemical reference substance |
| abstract | The present invention relates to the preparation methods of Penta-O-galloyl-D-glucopyranose chemical reference substance.Mango kernel refines three steps through ethanol water heating and refluxing extraction, then through polyamide column chromatography separation and reversed-phase silica gel column chromatography, can be obtained purity up to 98% or more Penta-O-galloyl-D-glucopyranose chemical reference substance.Present invention process step is simple, and the alcohol solvent of use is safe and non-toxic, and Penta-O-galloyl-D-glucopyranose chemical reference substance yield is high, and preparation amount is big. |
