| titleOfInvention | A method of preparing rhodioside chemical reference substance from Ledum palustre root |
| abstract | The present invention relates to a kind of methods that rhodioside chemical reference substance is prepared in root from Ledum palustre, and this approach includes the following steps：(1) silica gel column chromatography is enriched with：Ledum palustre root alcohol extract is detached through silica gel column chromatography, is eluted, and the rhodioside crude product up to brownish-yellow powder shape is dried under reduced pressure after thin-layer chromatography detects；(2) micro-porous resin cleans：Rhodioside crude product is through dissolving, micro-porous resin post separation, eluting, be dried under reduced pressure to get rhodiola root glycoside component；(3) reverse phase liquid prepares chromatographic refining：Rhodiola root glycoside component is detached through dissolving, filtering with microporous membrane and using efficient reverse phase liquid preparation chromatographic column, and collection prepares target chromatographic peak fraction in chromatogram, and the target chromatographic peak fraction is through being dried under reduced pressure the rhodioside reference substance up to white powder.Present invention process is simple, easy scale. |
