《中国药典》一九九七年增补本对《中国药典》一九九五年版的内容作了增订、修订(包括删去)和订正,其中对乙酰半胱氨酸等115种西药原料药增订了红外光谱法鉴别。红外光谱是分子的振动—转动光谱,特征性强,用于鉴别组分单一、结构明确的原料药,是一种较为合适的方法。但由于多数制剂中均加有辅料,因此,这些制剂不宜直接采用红外光谱作为鉴别。
The Chinese Pharmacopoeia 1997 Supplement The revised, amended (including deleted) and revised version of the 1995 edition of the Chinese Pharmacopoeia were revised and updated 115 pharmaceutical raw materials such as acetylcysteine Infrared spectroscopy identification. Infrared spectroscopy is a molecular vibration - rotation spectrum, characteristic, for identification of components of a single, well-defined API, is a more appropriate method. However, most preparations are added excipients, therefore, these preparations should not be used directly as the identification of infrared spectroscopy.
