| titleOfInvention | A kind of method that oleanolic acid is extracted from Talinum crassifolium |
| abstract | The present invention relates to a kind of method that oleanolic acid is extracted in use Talinum crassifolium root and stem.With petroleum ether degreasing, alcohol extracting, be concentrated under reduced pressure after ethyl acetate extracted, obtain the oleanolic acid product of high-purity through column chromatography and method for crystallising again.The method can make oleanolic acid in Talinum crassifolium rhizome be fully used, and effectively reduce its production cost, take full advantage of main active ingredient in Talinum crassifolium rhizome.Combined by column chromatography with crystalline phase, reduce chemical reagent excessively use, it is ensured that the pure natural property of product, can safety be supplied to the industries such as food, cosmetics and pharmacy. |
