制备方法与用途

概述

甜茶苷与甜叶菊糖苷结构相似，仅在C13位缺少一个葡萄糖分子。甜茶苷是一种无毒、高甜度且低热值的天然甜味剂，具有多种健康益处，如降血压、降血糖和促进新陈代谢等作用。此外，它还能够缓解胃酸过多症状，并广泛应用于食品和医药工业领域，已成功出口至日本及东南亚等地。

制备

一种高效提取甜茶苷的方法包括以下步骤：

1. 采用5克过60目筛的甜茶粉末，加入15毫升0.3%十二烷基二甲基甜菜碱表面活性剂。
2. 冷浸15分钟后，以固液比1:15，在65℃下超声功率为200W的条件下提取35分钟。此步骤重复进行两次。
3. 抽滤并合并滤液后使用旋转蒸发仪浓缩至无醇味。
4. 采用60%乙醇过夜醇沉处理，然后以4000转/分钟离心20分钟后收集上清液。
5. 使用AB-8树脂进一步纯化，用3体积倍数（BV）的60%乙醇洗脱液洗脱。此洗脱液经过D941柱进一步进行脱色和去蛋白处理后合并。
6. 合并后的柱流液及5体积倍数（BV）水洗液通过聚酰胺柱除去多酚、黄酮和苦味物质。
7. 最终收集的纯净甜茶苷液用水淋洗至无甜味，再将此液体喷雾干燥以获得白色极甜的甜茶苷。

经测定，此方法从甜茶中提取出5.91%的甜茶苷，提取率达到98.5%，基本上没有苦涩味。

检测方法

CN201410705364.X报道了一种快速检测甜茶苷的方法。该方法包括以下步骤：

1. 分别配制甜茶苷的标准样品及待测试样溶液。
2. 将标准样品在紫外检测器的波长范围190～400纳米之间进行扫描，以确定最佳吸收波长。
3. 使用反相高效液相色谱法对样品进行分析。具体条件如下：
   • 色谱柱：C18（5μm，150×4.6mm i.d）；
   • 流动相组成的体积比：甲醇:水 = 50～80:10～30；
   • 流速：1.0 mL/min；
   • 柱温：30℃；
   • 进样量：3～5μL。
4. 建立标准曲线，从而求出待测试样品溶液中甜茶苷的含量。

  摘要：

  变形链球菌通过变形蔗糖酶活性从蔗糖合成粘性不溶性葡聚糖，从而在人类龋齿的发展中发挥重要作用。为了探讨蔷薇科悬钩子中天然甜味剂成分甜叶悬钩子苷 (Ru) 的抗龋齿特性，我们研究了 Ru 对变异蔗糖酶活性和变异链球菌生长的抑制作用。 Ru (50 mM) 对含有 500 mM 蔗糖的 0.1 U/mL 变形链球菌变异蔗糖酶显示出 97% 的抑制活性。它表现出竞争性抑制，Ki 值为 1.1 ± 0.2 mM，IC50 为 2.3 mM。根据分子对接分析，其抑制活性归因于疏水性和氢键相互作用。 Ru 作为抑菌剂抑制变形链球菌的生长，MIC 和 MBC 值分别为 6 mM 和 8 mM。此外，Ru与姜黄素结合时表现出协同抗菌活性。因此，Ru是一种天然的抗龋齿剂，具有抗变异蔗糖酶活性和对变异链球菌的抗菌活性。
