| Abstract: | Triptolide was extracted from Tripterygium wilfordii Hook.f by pressurized liquid extraction with 1,2-dichloroethane.Main factors affecting the extraction process were discussed,and the optimum extraction conditions were obtained as: the solid to liquid ratio is 1:9.7,the extraction temperature is 115 ～C and the extraction time is 80 min.Under the optimized conditions,the actual yield and purity of triptolide were 0.173%o and 1.21% respectively.This process has obvious advantages as compared with conventional reflux extraction. |
