Extraction and determination of essential oil in different cultivars of Amomum tsao-ko
Essential oil in four cultivars fruits of Amomum tsao-ko were extracted and determined by the method of gas chromatography (GC) and GC-coupled mass spectrometry (GC-MS).The essential oils content of 86.50%,77.05%,83.02% and 77.50% were achieved in the four cultivars of Ellipse,Fusiform,Spherical,and Conical A.tsao-ko fruits,respectively.The results showed that the identified major common components of the essential oil are 1,8-cineole,citral,α-terpineol,α-phellandrene,α-pinene,β-pinene,γ-terpinen,and nerolidol,the most abundant component is 1,8-cineole which accounts for about 36% in all four cultivars and it may be useful for industrial exploitation as well as chemotaxonomic characterization.The results also indicated that the four A.tsao-ko fruit cultivars belong to eucalyptol-rich type and the observed chemical variability between the studied species and cultivars seems to results from the gengtic variability.
