Effects of waste batteries leaching solution stress on resistance physiological indices of volatile constituents from Schizonepeta tenuifolia / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>The effect of waste batteries leaching on the seedling growth and volatile constituents in leaves of Schizonepeta tenuifolia was assayed.</p><p><b>METHOD</b>The different concentrations of waste batteries leaching on the seedling growth were discussed. Volatile compounds were analyzed by solid-phase micro-extraction (SPME) coupled with gas chromatography-mass spectrometry (GC-MS).</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>Heavy metal leached by waste batteries had great effect on growth of S. tenuifolia, reducing its value for food and medical purposes.</p>
