Analysis of volatile constituents from Anemarrhena asphodeloides by GC-MS / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of the volatile oil from the rhizome of Anemarrhena asphodeloides.</p><p><b>METHOD</b>The volatile oil was steam distillation. Chemical constituents were separated and analyzed by GC-MS. The relative content of each component was determined by area nomalization.</p><p><b>RESULT</b>24 volatile compounds were isolated and identified for the first time, representing 70.83% of the total oil.</p><p><b>CONCLUSION</b>The main constituents of this oil were aldehydes (31.15%), terpene and their oxide (20.66%), alkyls (8.35%), Furan heterocyclic compounds (6.41%), non terpene alcohol (4.26%). There are 12 compounds with contents over 3%. Among them, borneol has the highest content (9.35%).</p>
