ABSTRACT
Membrane separation technology becomes the most promising separation technology in the 21st century due to its advantage of high efficiency, energy saving, and environmental protection. It has been extend applied in the areas of waste water treatment, food purification, biotechnology, environmental protection, and optimization. Chinese materia medica (including compoud) have rich resource and multi-component, as a special kind of material, separation operation runs through the entire process, which is the main part of the whole production process. Since the 90s of the 20th century, new separation technology materials and related technologies, such as membrane separation technology, macroporous resin technology in production industrial were gradually used in Chinese materia medica pharmaceutical industry in China. In this paper, the main research progress of membrane separation technology in the chemical constituents separation of Chinese materia medica in recent years are reviewed.
ABSTRACT
AIM: Clarification of sanchi(Panax notoginseng(Burk.)F.H.Chen) extract by ceramic microfiltration membrane was studied. METHODS: Different operating parameters on membrane flux were investigated.Membrane was cleaned by using strong base and strong acid.The effective compound of ginsenoside R_(g1) and notoginsenoside R_1 before and after microfiltration were studied. RESULTS: The sanchi extract became clear after microfiltration.The removal efficency of the whole solid was 31.3%,the metastasis rate of the effective ingredient was 84.8%,and the growth rate of the effective ingredient was 23.5%. CONCLUSION: The ceramic microfiltration technique is a feasible new one for clarification of sanchi extract.
