A kind of method for separating active ingredient from Luo Han Guo flower |
| abstract |
The present invention relates to a method for separating effective components from Luo Han Guo flowers. The method includes: S1, extracting Luo Han Guo flowers with steam to obtain moist flowers and a first extract; S2, extracting the moist flowers with ethanol as a solvent at 25-65° C. to obtain a second extract and a first filter residue, Concentrating and solid-liquid separation of the second extract to obtain a third extract and wet residue; S3, concentrating the third extract and standing to obtain crystals and a crystallization mother liquor; S4, placing macropores on the crystallization mother liquor The adsorption resin chromatography column is successively eluted with an acid solution, an alkali solution and an alcohol solution to obtain an acid eluent, an alkali eluent and an alcohol eluent, respectively. The method of the invention realizes the efficient and comprehensive separation of Luo Han Guo flowers. |
