| Abstract: | An arabinogalactan isolated from the wood of Larix sibirica L. was investigated by methylation analysis, partial hydrolysis, enzymic oxidation, and 13C-n.m.r. spectroscopy. The structural conclusions arrived at by 13C-n.m.r. spectroscopy were consistent with the data from methylation analysis. The polysaccharide is highly branched and similar in structure to those of arabino-3,6-galactans isolated from other Larix species. |
