中药中残留农药在制药工艺中的归属与去除

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者虑去除提取过程伴随溶出的残留农药．以避弁．残留农药可能的安全风险．

Determining the Organochlorinated Pesticides Dissolve Ratio Using Different Extract Methods

Authors studied three different ginsing OCPs extraction methods and associated effects. The three methods work with decoction and extraction at 95%-ethanol and 50%-ethanol respectively. The amount of OCPs extracted was measured by gas chromatography, and the extraction results were compared among the three methods. 95%-ethanol produced the highest extraction, followed by 50%-ethanol. The decoction sat at the lowest when the amount of OCPs was used as a standard. It is concluded that ethanol produces a much rich OCPs extraction, compared with decoction.
