面议ACQUITY UPLC BEH Shield RP18柱,除了C18链以外还包括一个亲水的氨基甲酸酯官能团(极性内嵌),从而对碱性分析物提供优异的峰形。该色谱柱也提供相对于直链烷基色谱柱的其它选择性。
1.7 µm的亚乙基桥杂化颗粒[BEH]是UPLC®技术得以实现的关键要素之一。该产品目前提供三种不同的粒径[130Å、200Å和300Å]以及几种用于反相色谱和亲水作用色谱的键合相,适用于从小分子分析到大分子生物制药分析的各类应用。杂化颗粒技术因其固有的化学稳定性而能采用更宽的pH范围[pH 1-12],从而可为方法开发提供一种通用且可靠的分离技术。
UPLC法测定地黄叶及块根中的梓醇和毛蕊花糖苷
目的比较地黄叶及块根中梓醇和毛蕊花糖苷的含有量.方法地黄叶及块根甲醇提取液的分析采用ACQUITY UPLC BEH Shield RP18色谱柱(2.1 mm×100 mm,1.7μm);柱温35℃;流动相为乙腈-0.1%磷酸水溶液,梯度洗脱;体积流量0.2 m L/min;检测波长210 nm.结果梓醇含有量由高到低,依次为地黄嫩叶(149.22 mg/g)老叶(49.29 mg/g)块根(33.33 mg/g)干叶(15.53 mg/g);毛蕊花糖苷含有量依次为地黄老叶(10.27 mg/g)干叶(10.03 mg/g)嫩叶(9.56 mg/g)块根(0.28 mg/g).结论地黄嫩叶中梓醇的含有量约为老叶的3倍,但毛蕊花糖苷的含有量略低于老叶.地黄叶存放一年后,毛蕊花糖苷的减少量比梓醇小,表明前者稳定性高于后者.而且,这两种成分在叶中的含有量均比在块根中更高.
