| titleOfInvention | The method of the isolated and purified 4,8-DHT of supercritical from hickory nut epicarp |
| abstract | The invention discloses supercritical from hickory nut epicarp isolated and purified 4, the method of 8-DHT, extracted by supercritical extraction reactor, it is extracted thing, extract methanol absorption, silica gel column chromatography, with petroleum ether and ethyl acetate mixed solvent gradient elution, every column volume collects one bottle of stream part, collect 10 bottles of stream parts altogether, 4th bottle of stream part concentrating under reduced pressure, crystallize by ethyl acetate, obtain 4, 8-dihydroxy-ALPHA-tetralone crystalline compounds, these are 4 years old, 8-DHT is 1:1 racemic modification, impurity is few, purity is 99.82%, extraction rate reached is to more than 60%, these are 4 years old, 8-DHT racemic modification has suppression plant seed germination and the effect of growth of seedling. |
