Extraction, isolation, purification and composition of Momordica charantia polysaccharide
摘要
Abstract
Crude polysaccharides were extracted from Momordica charantia with hot water. Three main fractions of Momordica charantia polysaccharides(MCP): MCP1 ,MCP2 and MCP3 were obtained through purification on DEAE-32 ion exchange column. The fractions were further isolated by Sephacryl S-400 gel-permeation chromatography. The results by Sephacryl S-400 and HPLC showed that MCP1 and MCP2 were both homogeneous. The molecular weight of MCP1 and MCP2 were 1.16 × 106 and 7.45 × l05, respectively measured by high performance gel permeation chromatography. The components of MCPs were determined by HPLC after PMP-derivatization. The results showed that MCP1 was heteropolysaccharides composed of Man, Rham, GlcUA, GalUA, Glu, Gal, Xyl and Ara, with respective molar ratios of 1.03 :2.93: 1.00: 14. 95:2. 16: 30. 70: 2. 85: 4. 50. MCP2 was composed of Rham, GalUA, Gal, Xyl and Ara, with respective molar ratios of 1.63: 21.88: 4. 66: 1.00: 1.29. No typical absorption of nucleic acid or protein was detected by UV scanning.关键词
