摘要
黎药木棉叶用石油醚除去脂溶性杂质,用水提醇沉法得海南木棉叶的多糖,采用苯酚-硫酸比色法对多糖含量进行了测定.测得木棉叶的多糖质量分数为0.72%,加样平均回收率为101.1%,相对标准偏差RSD为1.76%.
Petroleum ether was used to remove fat-soluble impurities, with Water Extracting-Alcohol Precipitating to get the polysaccharide from leave of Bombax malabaricum DC. The content of polysaccharide was determined with phenol - sulfuric acid colorimetry. The mass fraction of polysaccharide from leave of Bombax malabaricum DC was determined as 0.72% with average recovery of 101.1% and the RSD of 1.76%.
