Application of ceramic filter membrane in purification technology of water extract from Shensong Yangxin Capsule / 中草药

ABSTRACT

Objective To observe the effect of different pore diameter membranes on technologies of water extract from Shensong Yangxin Capsule and optimize the parameters. Methods Three different membranes were tested to observe the changes in membrane flux and the retention of effective components. Results The membrane with 100 nm diameter had the greater membrane flux, the transfer rates of paeoniflorin was the highest. The optimum conditions were that the operation differential pressure was 0.15-0.22 MPa, the operation temperature was 20°C. Conclusion A good result can be obtained by adopting the technology of ceramic membranes filtration to purify Shensong Yangxin Capsule, which provides the foundation for the application of ceramic membranes micro-filtration in the purification of water extract of other Chinese materia medica.
