ABSTRACT

AIM:To observe the influence of the different bore diameter ceramic membranes on the processing parameters of Jinlida Granules(Radix et Rhizoma Salviae miltiorrhizae,Radix Sophorae flavescentis,Rhizoma Polygonati,etc.) and optimize the process of membrane filtration. METHODS: Three different membranes were tested to observe the changes in membrane flux and the content of effective components by Jinlida Granules extract. RESULTS: The 50 nm membrane had the great flux,the transfer rates of matrine and salvianolic acid were the highest;The optimum conditions: the operation differential pressure was 0.08~0.12MPa;the operation temperature was 50~60℃;the membrane surface flow rate was 3.0 m/s.When the volume of filtration solution was condensed to one tenth,adding the same volume aeionized water,and the effective components transfer rate reached 80%.Using the strong acid and strong alkali to wash it in turn,the flux can revivify above 90%. CONCLUSION: Applying the ceramic membrane to ultrafiltrate Jinlida Granule is good and useful to herb purification.
