Herein we describe for the first time a practical analytical method for determining the enantio-purity of L-α-glycerophosphocholine (L-α-GPC) by chiral derivatization. The use of a suitable chiral boronic acid allowed the formation of a mixture of two diastereomeric boronate esters whose ratio, carefully analyzed by HNMR spectroscopy, reflects L-α-GPC enantiomeric excesses. The determination of the enantiopurity of L-α-GPC furnishes convincing correlations with its manufacturing process.
在此,我们首次描述了一种实用的分析方法,通过手性衍生化来测定 L-α-甘油磷酸胆碱(L-α-GPC)的对映体纯度。使用合适的手性硼酸可以形成两种非对映异构体硼酸酯的混合物,通过 1H NMR 光谱仔细分析其比例可以反映 L-α-GPC 的对映体过量。L-α-GPC 对映体纯度的测定与其制造工艺有很好的相关性。
