采用不同的提取方法，从荸荠种子中获得水溶性（WSP）、碱溶性（ASP）和不溶性（IMP）三种多糖。分析了WSP、ASP和IMP的水分、灰分、蛋白质和总碳水化合物含量。WSP中含有丰富的葡萄糖、鼠李糖、阿拉伯糖和半乳糖，同时还检测到少量木糖。WSP和ASP的单糖组成及其相对含量相似。特征黏度结果表明，ASP的特征黏度明显低于WSP，说明部分多糖在碱性提取过程中被降解为低分子量聚合物。多糖的急性抗炎活性结果表明，WSP对急性炎症具有抑制作用。
Three polysaccharides (water-soluble (WSP), alkali-soluble (ASP) and insoluble (IMP)) from boat-fruited sterculia seeds were obtained using different extraction methods. Moisture, ash, protein and total carbohydrate content of WSP, ASP and IMP were analyzed. WSP was rich in glucose, rhamnose, arabinose and galactose while small amount of xylose was also detected. The monosaccharide composition as well its relative content for WSP and ASP were similar. The intrinsic viscosity results demonstrated that ASP had much lower intrinsic viscosity than WSP, indicating partial polysaccharides were degraded into low molecular weight polymers during alkaline extraction. The acute anti-inflammatory bioactive results of polysaccharides indicated that WSP demonstrated an inhibitive effect toward acute inflammation.
