Abstract
A procedure for the determination of the diastereoisomer ratio in phenethicillin potassium and its formulations is described. The method utilizes analyses of PMR and 13C-NMR data. Assignments of 13C-chemical shifts in D- and L-phenethicillin potassium also are included.
摘要
描述了一种测定苯氧乙基青霉素钾及其制剂中非对映异构体比例的方法。该方法利用了核磁共振氢谱（PMR）和碳-13核磁共振谱（13C-NMR）数据进行分析。文中还包括了D-型和L-型苯氧乙基青霉素钾中碳-13化学位移的归属。
