| titleOfInvention | A kind of extraction process of ginsenoside Rd |
| abstract | The invention discloses the extraction processes of ginsenoside Rd a kind of, comprising: S1 is extracted by the pulverizing medicinal materials containing ginsenoside Rd's ingredient at medicinal powder with 70%~95% alcohol reflux, is recycled ethyl alcohol and is concentrated, obtains total extract；S2 takes total extract, is crossed D101 macroporous absorbent resin, with 40%~80% ethanol elution, recycles ethyl alcohol and is concentrated under reduced pressure, obtain total saposins；S3 takes total saposins, is crossed silica gel column chromatography, with n-butanol-ethyl acetate-water isocratic elution, merges fraction through thin-layer chromatography inspection, obtains ginsenoside Rd's crude product；S4 takes ginsenoside Rd's crude product, is crossed Rp-C18 silicagel column, and with methanol-water isocratic elution, component needed for merging after thin-layer chromatography checks is precipitated precipitating, obtains ginsenoside Rd.What the present invention can improve ginsenoside Rd isolates and purifies effect, avoids the use of toxicity organic reagent, and easy to operate, production process is easily controllable, is suitable for industrialized production. |
