| Abstract: | The feasibility was discussed that adopting SCF-CO_2 to extract effective constituent(piceid,resveratrol and emodin)from Chinese herb Polygonum cuspidatum.Extracting effective constituents by SCF-CO_2 was studied under varying extraction conditions and different pretreatments.The effect of factors on SCF-CO_2 was examined respectively, and the best extraction conditions are obtained. |
| Keywords: | SCF-CO_2 extraction Polygonum cuspidatum effective constituents |
