摘要
采用水提醇沉法提和有机酸沉降法进行罗望子多糖的提取,并对两种方法进行了对比分析.结果显示:水提醇沉法提取罗望子多糖的平均提取率为70.34%,有机酸沉降法平均提取率为63.52%.从平均提取率看,水提醇沉法明显高于有机酸沉降法.但从红外光谱及部分性质的测定结果看,水提醇沉法提取纯度不及有机酸沉降法.
Two polysaccharide extraction methods of tamarind seed were analyzed and compared in the experiments.The result shows that the extraction rate of water extraction and ethanol precipitation is much higher than that of organic acid sedimentation,with the average extraction rate at 70.5% and 63.5%,respectively.However,in the term of the IR spectral result and some properties of tamarind seed polysaccharide,water extraction and ethanol precipitation is inferior to organic acid sedimentation.
