Abstract
The assay of ointments containing nitroglycerin is described. Sample preparation by direct dissolution in warm dimethyl sulfoxide appeared to be more accurate than extraction. Anisole was used as an internal standard. Chromatographic conditions included a C18 microporous silica column and a methanol-water mobile phase (40:60). Detection of 215 nm was superior to detection at 254 nm.
摘要
描述了含硝酸甘油软膏的测定方法。直接溶解于温热二甲基亚砜中的样品制备方法似乎比萃取法更准确。使用苯甲醚作为内标。色谱条件包括C18微孔硅胶柱和甲醇 - 水流动相（40:60）。在215nm处检测优于在254nm处检测。
