A polysaccharide (PS-I) isolated from the aqueous extract of the unripe (green) tomatoes (Lycopersicon esculentum) consists of D-galactose, D-methyl galacturonate, D-arabinose, L-arabinose, and L-rhamnose. Structural investigation of the polysaccharide was carried out using total acid hydrolysis, methylation analysis, periodate oxidation study, and NMR studies ((1)H, (13)C, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC). On the basis of above-mentioned experiments the structure of the repeating unit of the polysaccharide (PS-I) was established as: [structure: see text].
从未成熟（绿色）番茄（Lycopersicon esculentum）的水提物中分离得到的一种多糖（PS-I）由 D-半乳糖、D-甲基半乳糖醛酸、D-阿拉伯糖、L-阿拉伯糖和 L-鼠李糖组成。通过完全酸水解、甲基化分析、高碘酸盐氧化研究和 NMR 研究（1H、13C、DQF-COSY、TOCSY、NOESY、ROESY、HMQC 和 HMBC）对多糖的结构进行了研究。基于上述实验，确定了多糖（PS-I）的重复单元结构为：[结构：见正文]。
