Hydrolysates were derivatized to the alditol acetates with acetic anhydride-pyridine (Albersheim et al, 1967) and analyzed by CGL using a capillary column Sp 2330 (Supelco) (30x0,25 mm) on a HP-5890 Gas Chromatograph equipped with a flame ionization detector (FID).
Insoluble and soluble non-starch polysaccharides (NSPs) were analyzed by gas chromatography (VARIAN, CP-3800, Walnut Creek, CA, USA) as the alditol acetate derivatives of monosaccharide based on the method developed by Englyst and Hudson (1993), and Theander and Westerlund (1993).
The results of GCMS analysis of the partially methylated alditol acetates showed that the EPS consisted of five methylated fragments with different molar ratios (Table 1).
Secondly, it was established that the lipid was alkali stable and on acid hydrolysis yielded two major sugars, tentatively identified by comparative gas chromatography (GC) as the alditol acetates of the 6-deoxyhexoses, 3,4-di-O-methylrhamnose and 2,3-di-O-methylfucose.
Individual neutral sugars were analyzed as their alditol acetates by gas-liquid chromatography (GLC) using an HP 5890 SII with FID system, equipped with a capillary column (025 mm [empty set] x 30 m, model B-210, with film 0.
The monosaccharide composition was estimated by gas-chromatography-mass-spectrometry (GC-MS) of alditol acetate derivates using the reductive hydrolysis procedure (STEVENSON; FURNEAUX, 1991).
