| titleOfInvention | A kind of method that high content of alpha mangostin is extracted from mangosteen skin |
| abstract | The invention discloses a kind of method that high content of alpha mangostin is extracted from mangosteen skin, it comprises the following steps：(1) extract：Mangosteen skin raw material is taken, after crushing, is placed in extraction element, add the acid alcohol solvent of 4~5 times of its weight, be placed in 85~95 DEG C of water-baths, extracted 2~3 times, 1.5~2h, merges each extract solution and filter, the extract solution after being filtered every time；(2) chromatograph：By step (1) gained filtered fluid, after crossing neutral alumina chromatographic column, gradient elution is carried out, collect eluent, eluent is concentrated under reduced pressure into without alcohol taste, then at 4 DEG C of placement >=4h to there is crystal to separate out, be then centrifuged for, taking precipitate, as finished product.Step of the invention is few, it is time-consuming less, it is few reagent dosage, low cost, simple to operate, easy to control, can highest obtain the α mangostins of content >=99.0%, be adapted to industrialized production. |
