Studies on the chemical constituents of the volatile oil from Radix Cudramiae / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of the volatile oil from Radix Cudramiae.</p><p><b>METHOD</b>The oil was obtained by steam distillation. The chemical compositions were separated and identified by GC-MS. The relative contents in the oil were determined by area nomalization.</p><p><b>RESULT</b>Sixty-four compounds were obtained from Radix Cudramiae. The relative contents of twenty-three compounds were more than 1%. The highest relative content was L-linalool (9.852%).</p><p><b>CONCLUSION</b>Sixty-four compounds characterized by GC-MS analysis were obtained from Radix Cudramiae for the first time.</p>
