A water-soluble polysaccharide isolated from the hot water extract of the green fruits of Capsicum annuum was found to consist of 3-O-acyl-L-rhamnose, D-methyl galacturonate, 6-O-methyl-D-galactose in a molar proportion of nearly 1:2:1. Structural investigation of the polysaccharide was carried out using total hydrolysis, methylation analysis, periodate oxidation followed by GLC-MS, and NMR experiments. On the basis of the above-mentioned experiments it is concluded that the following repeating unit is present in the polysaccharide.
从辣椒绿色果实的热水提取物中分离出的一种水溶性多糖，被发现由3-O-酰基-L-鼠李糖、D-甲基半乳糖醛酸、6-O-甲基-D-半乳糖以摩尔比近1:2:1组成。使用完全水解、甲基化分析、高碘酸盐氧化后接气相色谱-质谱联用以及核磁共振实验对该多糖进行了结构研究。基于上述实验得出结论，该多糖中存在以下重复单元。
