摘要
利用气相色谱-质谱联用法对印度和中国新疆万寿菊提取加工过程中的苯进行检测。结果表明,不同来源的万寿菊提取物中存在不同程度的苯(1.17~16.37 mg/kg)污染,对生产过程相关样品进行检测,发现提取溶剂中不同程度含有苯,从生产过程推理,提取溶剂应该是万寿菊提取物中苯的主要来源。在生产中要控制产品中苯的污染,首先应加强对提取溶剂的控制。
Benzene in marigold extract were quantified by gas chromatography–mass spectrometry(GC/MS). Marigold were collected from India and China(Xinjiang),marigold extract was extracted in laboratory. The results showed that benzene with 1.17 to 16.37 mg/kg was found in marigold extract samples;and benzene was detected in extraction solvent. During preparation of marigold extract,benzene migrated from solvent to marigold extract. This indicated that benzene in marigold extract came from extraction solvent. The conclusion is to control benzene contamination of marigold extract,extraction solvent must be ensured without benzene.
