Abstract

A xyloglucan (XG) was extracted from the seeds of Hymenaea courbaril (Jatoba) harvested from trees growing at different locations in Brazil. They were from Foz do Chopin Forest Reserve, State of Parana (HC-I), Cuiaba (HC-II) and Sinope/State of Mato Grosso (HC-III), Natal/State of Rio Grande do Norte (HC-IV), Fortaleza/State of Ceara (HC-V) and Tamarindus indica (TM) from Conceicao de Almeida/State of Bahia, Brazil. It was submitted to SEC-MALLS analysis and its intrinsic viscosity determined. When a solution of XG was heated to 85 degrees C for 2 h, there was a reduction of aggregation and the XG from the seeds of H. courbaril had a higher value of C. when compared with that of from T indica, probably due to the presence of an unique oligossacharide series present in the H. courbaril samples (XXXXG). This gives rise to a more rigid molecule when compared with the XG from T. indica. (c) 2005 Elsevier Ltd. All rights reserved. (AU)
