一般說明

异槲皮苷是一种类黄酮类化合物,是槲皮苷的糖苷衍生物,也是蛋白质二硫异构酶(PDI)抑制剂。它可从药用植物的叶片中提取,如罗布麻,具有优异的抗氧化性和抗血栓活性。
由HWI pharma services GmbH生产并鉴定。
通过定量NMR测定的准确含量可参见证书。

應用

主要参考标准品可用于鉴定、分析和纯度检测、方法开发和验证。它还可用于:
  • 开发发协同云点萃取(SCPE)法,用以提取大鼠血浆样品中的异槲皮苷,并随后通过高效液相色谱(HPLC)进行分析
  • 使用基于碳纳米管电极的循环伏安法对异槲皮苷和表没食子儿茶素没食子酸酯进行电化学分析
  • 使用硫代-β-环糊精功能化石墨烯/钯纳米颗粒(SH-β-CD-Gr/PdNP)修饰的玻碳电极(GCE),通过差分脉冲伏安法(DPV)同时对芦丁和异槲皮苷进行测定
  • 利用高效液相色谱-二极管阵列检测法,对虎杖干茎和花提取物中异槲皮苷、甾醇、大黄素8-O-β-D-葡萄糖苷和槲皮素进行多重残留分析
