说明

α-常春藤素是一种水溶性五环三萜化合物，存在于黑种草种子中。

α-常春藤素可用作液相色谱/串联质谱 (LC-MS/MS) 测定人血浆中甘草甜素及其主要代谢物甘草次酸的内标。 可作为高效液相色谱-光电二极管阵列检测（HPLC-PDA）和超高效液相色谱-四极杆飞行时间质谱（UPLC/Q-TOF）测定奎诺维酸苷的外标 -多发性硬化症）。 可作为液相色谱-电喷雾串联质谱（LC-EI/MS-MS）鉴定常春藤（Hedera helix）叶片中α-常春藤素的参考标准。

一般描述

α-Hederin is a water-soluble pentacyclic triterpene compound present in the seeds of Nigella sativa.

应用

α-Hederin may be used as an internal standard for the determination of glycyrrhizin and its major metabolite glycyrrhetic acid in human plasma by liquid chromatography/tandem mass spectrometry (LC−MS/MS). It may be used as an external standard for quinovic acid glycosides assay by high performance liquid chromatography-photodiode array detection (HPLC-PDA) as well as ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS). It may be used as a reference standard for the identification of α-hederin in the leaves of common ivy (Hedera helix) by liquid chromatography-electrospray ionization tandem mass spectrometry (LC-EI/MS-MS).
