국내산 소나무와 금강송의 헤미셀룰로오스 비교 분석

Hemicelluloses difference between Korean red pine and Geumgang pine was investigated by acid hydrolysis and $^1H-NMR$ spectroscopic method. In galactoglucomannan of sapwood, acetic acid:galactose:mannose ratio was 4.0:1.9:11.5 for Geumgang red pine but 3.8:6.1:10.2 for Korean red pine, which meant Korean red pine had galactose-rich glucomannan but Geumgang pine had galactose-poor glucomannan. In arabinoglucuronoxylan, arabinose:glucuronic acid:xylose ratio was 0.9:0.9:4.2 in Geumgang red pine but 1.0:1.2:4.0 in Korean red pine, which meant higher arabinose to xylose ratio in Geumgang red pine than Korea red pine. Based on hemicelluloses analysis, it is possible to distinguish between Korean red pine and Geumgang red pine.
