Abstract:
Object To research and choose the best technology c onditions for extracting ursolic acid from Sambucus chinensis Li ndl. Methods According to physicochemical character of ursolic aci d, orthogonal design and tests of extract technology for ursolic acid were ca rried on, and four factors were chosen such as concentration, qu an tity of ethanol, extracting time, concentration of clearing agent, and three lev els of each factor were used for orthogonal design and test. Results That was the best technology condition that ursolic acid was extracted by means of ethyl alcohol (90%) of 7 times as much as raw materials, and it is heat ed 2 times (each 1 h), and the concentration of clearing agent was 3%. Conclusion That is a better technology for industrial producti on because it is advanced and rational, practical and feasible.
