Abstract:
OBJECTIVE: To develop a rapid, accurate and sensitive method for the determination of nifedipine, nitrendipine and nimodipine which were added into traditional patent medicine illegally. METHODS: The LC-MS method was used to detect the extractive of Chinese patent medicine for antihypertension in respects of relative molecular mass, tandem mass spectrometry fragment, retention time, UV spectrum. The compounds added into the Chinese patent medicine were identified by comparing with standard sample in terms of spectrum, chromatographic and mass spectrometric behavior. RESULTS: According to four aspects of determination, nifedipine, nitrendipine and nimodipine were found in three kinds of Chinese patent medicine for antihypertension. CONCLUSION: The method is selective and sensitive for the detection of nifedipine, nitrendipine and nimodipine which were added into traditional patent medicine illegally.
