GC-MS Determination of Components of Volatile Oil from Curcuma Rhizoma with Head-Space Solid Phase Micro-extraction
摘 要
采用顶空固相微萃取-气相色谱-质谱法分离和鉴定莪术挥发油成分,用归一化测定其相对含量。共分离出64个组分,鉴定出57种化合物,其含量占总挥发油组分峰面积98.02%。主要挥发成分及其含量为β-榄香稀(18.73%)、β-榄烯酮(11.03%)、莪术二酮(8.47%)、γ-榄香稀(6.79%)。

Abstract
Components of volatile oil of Curcuma rhizoma were separated and identified by head-space solid phase micro-extraction and GC-MS in hyphenation, and their relative contents (in %) were found by the method of normalization. Totally 64 compounds were separated among which 57 compounds were identified and determined, amounting to 98.02% of the total peak areas of the components of the volatile oil. The main compounds found with their relative contents were as follows: β-elemene (18.73%), β-elemenone (11.03%), curdione (8.47%) and γ-elemene (6.79%).
