Structural analysis of Asian lacquer polysaccharides in Vietnam, Myanmar, Cambodia, Taiwan, and Japan was carried out by a combination of chemical and physical methods, and then their structures were compared with that of a Chinese lacquer polysaccharide reported previously. It was found that the structure of polysaccharides in China and Japan, Taiwan and Vietnam, Myanmar and Cambodia, was similar to each other. The polysaccharides in Myanmar and Cambodia had larger amounts of L-arabinose and L-rhamnose than those in other Asian lacquer polysaccharides. In addition, the degradation process of lacquer polysaccharide was revealed for the first time by the time-course of GPC measurements of polysaccharide in Aizu, Japan. The results suggest that the molecular weight of polysaccharide in lacquer tree had around Man=67 x 10^3 with narrow molecular weight distribution and then decreased gradually into two molecular weight fractions of Man=67 x 10^3 and Man=23 x 10^3 in the proportion of 25 and 75 mol% isolated after 3 weeks.10.

采用化学和物理相结合的方法，对越南、缅甸、柬埔寨、台湾和日本等地的生漆多糖进行了结构分析，并与中国生漆多糖的结构进行了比较。结果表明，中国与日本、台湾与越南、缅甸与柬埔寨的多糖结构相似。缅甸和柬埔寨漆多糖中L-阿拉伯糖和L-鼠李糖的含量高于其他亚洲漆多糖。此外，在日本会津，漆多糖的GPC测量的时间过程中，首次揭示了漆多糖的降解过程。结果表明，漆树多糖的分子量约为Man=67 x 10^3，分子量分布较窄，然后逐渐下降为Man=67 x 10^3和Man=23 x 10^3两个分子量级分，分离比例为25和75mol% 3周后。10.
