Keyword:  人参有机氯农药气相色谱溶出率提取转移率;
Abstract: 目的:探讨3种提取工艺情况下人参中有机氯农药的归属.方法:采用水煎煮工艺及95%乙醇、50%乙醇加热回流工艺对人参有效成分进行提取后,用毛细管气相色谱法测定煎煮(提取)液中的有机氯农药含量.结果:以95%醇提溶出率最高,50%醇提溶出率次之,水煎过程溶出率最少. 结论:醇提对中药材中有机氯农药有较高的溶出率,而水煎煮过程对中药材中有机氯农药的溶出率很低,残留农药大部分随药渣去除.因此情况允许的条件下应尽量采用水煎工艺提取药材中的有效成分,必须采用醇提工艺时应考虑去除提取过程伴随溶出的残留农药,以避免残留农药可能的安全风险.
