| Abstract: | The extraction technology of oleanolic acid in Zizyphus jujuba mill was studied with ethanol as extractor. The contained amount of quercitr was assayed by HPLC. The best conditions were chosen through L9(34) orthogonal test. The results showed the first factor affecting extraction rate was volume percentage of ethonal, and the second and the third ones were temperature and rotio of feed liqued respectively. The best extraction conditions were 70% ethanol as extractant with the granularity of 100 mesh at the temperature of 50 ℃ for 3 h. The extraction rate was 1.549 g/kg. |
