制备方法与用途

甘露三糖

应用 甘露三糖是一种天然的功能性寡糖,能有效增加人体肠道内有益菌群(如双歧杆菌和乳酸菌)的数量,具有良好的生理功能。

制备方法 一种由鲜地黄制备高纯度甘露三糖的方法如下:

  1. 鲜地黄加工炮制: 取采收后的鲜地黄25.0g,去除非新鲜部分后,洗净并切成厚度为3cm的切片。将这些切片密闭加热至90℃,保持6小时。

  2. 甘露三糖样液制备: 按1:2的质量比将步骤1中得到的鲜地黄加工炮制品加入70℃的水中浸提0.5小时。残渣按相同工艺继续浸提1次,合并浸提液后真空浓缩至60.Brix,即得甘露三糖样液。

  3. 醇沉处理: 按体积比1:2的比例向甘露三糖样液中加入乙醇,在80℃下保温30分钟。自然降温静置24小时,得到甘露三糖样液醇沉部分。

  4. 除杂脱色与浓缩: 将步骤3所得的醇沉甘露三糖样液用水稀释10倍,并用0.5%的活性炭或大孔吸附树脂(上样液重量与树脂体积比例为450g/L)进行脱色处理。过滤后,在60℃条件下浓缩至60.Brix。

  5. 分离纯化: 将甘露三糖样液稀释到10.Brix,通过凝胶LH20柱色谱以25%的乙醇洗脱。用TLC检测并合并含甘露三糖的馏分,浓缩或冷冻干燥后得到甘露三糖。最终纯度为98.5%,总收率为4.4%。

生物活性 甘露三糖(Manninotriose)是小野芝麻的主要碳水化合物之一(Lamium款冬,唇形科)。其化学性质表现为白色结晶粉末,并可溶于甲醇、乙醇及DMSO等有机溶剂。甘露三糖来源于玄参科植物地黄。

用途 甘露三糖具有促进造血细胞增殖、提高免疫力、降血糖和抗肿瘤等多种药理活性。
