摘　　要：目的:研究废旧电池浸出液对荆芥幼苗生长及叶片挥发性成分的影响。方法:探讨不同浓度废旧电池浸出液对荆芥幼苗生长的影响,并用固相微萃取技术与气相质谱联用对叶片中挥发性成分进行分析。结果:荆芥幼苗对废电池浸出液具有一定的抗性,但高质量分数废电池浸出液对荆芥的生长有一定的抑制作用;不同浓度废电池浸出液对荆芥挥发性成分影响较大。结论:废旧电池在水中渗出的化学物质对荆芥产生很大影响,降低荆芥的食用和药用价值。Objective： The effect of waste batteries leaching on the seedling growth and volatile constituents in leaves of Schi- zonepeta tenuifolia was assayed. Method： The different concentrations of waste batteries leaching on the seedling growth were dis- cussed. Volatile compounds were analyzed by solid-phase micro-extraction （SPME） coupled with gas chromatography-mass spectrome- try （GC-MS）. Result： The results indicated that S. tenuifolia showed resistance to heavy metal polluting, but the high rate of waste batteries leaching had the inhibiting effect to seedlings growth. The waste batteries leaching cause the major volatile constituents in leaves of S. tenuifolia was changed greatly under waste batteries leaching solution stress. Conclusion： Heavy metal leached by waste batteries had great effect on growth of S. tenuifolia, reducing its value for food and medical purposes.
