Abstract: Successive aqueous (10 ºC, 25 ºC and 80 ºC) and alkaline (1M NaOH; 25 ºC) extractions of milled Parkinsonia aculeata endosperms gave rise to four galactomannan fractions. These extractions furnished viscous galactomannans with Man:Gal ratios ranging from 3.1:1; 3.7:1; 4.9:1 and 6.1:1 (P1, P2, P3 and P4, respectively). Fraction P1 was used for structural studies by using methylation analysis, periodate oxidation and 13C-NMR. It showed a linear backbone of beta(1->4) linked D-mannose units, to which single alpha… Show more

“…This concentration was different from that suggested by Garros-Rosa et al (2006), Lima et al (2002) and Seshagirirao et al (2005). Garros-Rosa et al (2006) and Moreira et al (1998) using matrices with a higher final concentration of ECH (A 2 formulation).…”

“…This was unexpected, since these lectins have similar compositions and structures. The galactomanann matrices used by Moreira et al (1998) and Garros-Rosa et al (2006) demonstrated greater interaction with the A. incisa than the C. pulcherrima matrices. This could be due to the galactose distribution, and the galactose/manose ratio.…”

“…It is a saturated fatty acid without any double bonds or functional groups other than the carboxyl group. Guar gum was chosen because it is a non‐ionic (neutral) polysaccharide gum with a high galactose : mannose ratio (1:2) compared with other galactomannans (Garros‐Rosa et al . 2006), which makes it highly water soluble.…”

“…45 Over the last few decades, many reports have appeared on the composition and physiochemical properties of galactomannans from different plant sources. 6,33,[36][37][38][40][41][42][43][44][46][47][48][49][50][51][52][53][54][55][56][57][58][59] However, only guar, locust bean, tara and cassia gum are manufactured on a large scale, and these are being extensively investigated by various researchers. 5,11,12,19,21,[60][61][62][63][64][65][66] Srivastava and Kapoor 6 described, in their overview of galactomannans, chemical screening of more than 300 Indian species of water-soluble gums.…”
