Abstract
This paper studied the technology for isolation and purification of 1-Deoxynojirimycin (DNJ) from Morus alba L. leaves by using AB-8 macroporous resin and 732 H type cation exchange resin sequentially, with the content and recovery rate of DNJ as indexes. The result showed that AB-8 resin was suitable for the preliminary isolation and purification of DNJ. At pH 4.0, the maximum loaded amount of Morus alba L. leaves extract was 2BV and the recovery rate of DNJ was 98% by collecting the solution flowing out at lBV/h as flowing rate. The content of DNJ was enhanced to 4.9%. 732H type cation exchange resin chromatography was used to purify continuously. Elution order is: 1 BV H2O-1.5 BV 0.3 M NH3-2BV 0.5 M NH3. The final output was obtained by collecting the fraction with pH 9.0-10.0. The final total DNJ content was 16.7%. The technology is suitable for large scale manufactory of extract rich of DNJ.关键词
