The contents of neutral polysaccharide and hexuronic acid were individually determined by the phenol-sulphuric acid method and the method of Blumenkrantz and Asboe-Hansen. The monosaccharide and amino acid compositions of LP1-3 were determined by gas chromatograph/mass spectrometer and reverse phase-high performance liquid chromatography, respectively. The values for neutral polysaccharide, hexuronic acid, and protein were expressed as mean ± SD (n = 3). The results having the different letter in each row are significantly different (P < 0.05), * represents hydrophobic amino acid.
