【摘要】 采用毛细管气相色谱-质谱以及气相色谱Kouvats保留稻指教之双重鉴定方法,从新疆种植的伞形科植物孜然的精油中鉴定出17种化合物,占总油量的94％,枯茗醛(37.01％)及桃金娘烯醛(22.92％)是该精油的主要成分。红外光谱中有芳香醛和α、β不饱和醛的特征吸收峰,为上述鉴定出的主要成分提供了佐证。桃金娘烯醛等5种成分在本植物中系首次报道。更多还原

【Abstract】 Seventeen chemical constituents of essential oil of Cuminum cymimu- ml L.);of family Umbelliferae)were assayed and identified by both capillary gas chromatography/mass spectrometry and the Kouvats Index of them.The major components were cuminaldehyde （37.01％）and Myrte- nal （22.92％）.The absorptions at 1702cm^-1 and 2721cm^-1 inthe oil’s IR spectrum showed aromatic aldehyde and α,β unsaturated aldehyde groups, thus providing further evidences for the above findings.This work isco- nsidered to have priority over other researches concerning the discovery of Myrtenal & 4 other ingredients within the volatile oil of this plant.更多还原
