采用有机溶剂提取大麻活性成分后,再用气相色谱内标法检测大麻中大麻二酚(CBD)、△~9-四氢大麻酚(△~9-THC)和大麻酚(CBN)三种活性成分的方法,方法简便,结果准确。用于全国十个省市大麻样品的检测,对其中大麻主要产区——新疆和云南大部分地区大麻活性成分含量进行了普查,从而取得了我国大麻中活性成分含量情况的第一手资料。在检测方法建立过程中,作者成功地从大麻植物中提取分离出CBD、△~9-THC和CBN对照品。解决了检测中面临的难题。 After the active ingredients of hemp were extracted with organic solvents, the three activities of cannabidiol (CBD), △-9-THC and cannabinol (CBN) in cannabis were detected by gas chromatography internal standard method. The composition method is simple and accurate. For the detection of cannabis samples in ten provinces and cities across the country, the content of active ingredients of cannabis in the major producing areas of cannabis, Xinjiang and Yunnan, was surveyed, and the first-hand information on the content of active ingredients in cannabis in China was obtained. During the establishment of the detection method, the author successfully extracted and isolated CBD, △~9-THC and CBN reference products from hemp plants. Solved the problems faced in the detection.
