Abstract

A mucilage, designated as MSL-M, was isolated from the leaves of Malva sylvestris L. var. mauritiana Mill. It was homogeneous on electrophoresis and gel chromatography. Its intrinsic viscosity value in aqueous solution was 12.0, and its molecular weight was estimated to be about 6.0 x 10(6). The major constituent is an acidic polysaccharide composed of L-rhamnose: D-galactose: D-galacturonic acid: D-glucuronic acid in the molar ratio of 6:3:2:2. Methylation analysis of both the mucilage and the carboxyl-reduced derivative, carbon-13 nuclear magnetic resonance and partial hydrolysis studies indicated its main structural features. It has considerable anti-complementary activity.

摘要

从锦葵（Malva sylvestris L. var. mauritiana Mill.）叶片中分离出一种名为MSL-M的黏液。该黏液在电泳和凝胶色谱上均表现为均一性。其在水溶液中的特性黏度值为12.0，分子量估计约为6.0×10⁶。主要成分是一种酸性多糖，由L-鼠李糖、D-半乳糖、D-半乳糖醛酸、D-葡萄糖醛酸按摩尔比6:3:2:2组成。对该黏液及其羧基还原衍生物进行的甲基化分析、碳-13核磁共振和部分水解研究表明了其主要结构特征。它具有相当强的抗补体活性。
