| Abstract: | Objective: It was studied to extract oleanolic acid from waste residue of grape winery. Methods: Ethanol (EtOH) extract was charged by acid and NaOH sol. Orthogonal design was used to optimize the better extract conditions. Result: The better extract conditions: First, waste residue was twice extracted by 95% EtOH. Second, add acid to pH1 to separate the crystal out. Third, the semifinished product was washed by 5%NaOH sol. three times. The obtained product's purity is 95. 67% and the rate of obtain is 0. 71%. Conclusion: The better extract conditions can be get through the extracting of EtOH and the processing of acid and 5%NaOH sol. |
