An amendment to the fine structure of galactoxyloglucan from Tamarind (Tamarindus indica L.) seed

A polysaccharide from tamarind seeds (TSP) was characterized in terms of backbone and side chain structural features, as well as conformational property using methylation and GC–MS analysis, 2D NMR, MALDI-TOF MS, and high performance size exclusion chromatography (HPSEC). Results showed that TSP was a galactoxyloglucan (GXG) consisting of glucose, xylose, and galactose in a molar ratio of 3.1: 1.7: 1.0. The Mw was determined to be 524.0 kDa with...
