ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of the volatile oil from the aerial parts of Isodon eriocalyx var. laxiflora.</p><p><b>METHOD</b>The oil was obtained by hydrodistillation. The chemical compositions were separated and identified by GC-MS. The relative contents in the oil were determined by area normalization.</p><p><b>RESULT</b>163 peaks were separated and 105 compounds were identified, constituting 85.68% of the total peak area.</p><p><b>CONCLUSION</b>105 compounds characterized by GC-MS analysis were found from I. eriocalyx var. laxiflora for the first time.</p>
