The volatile oils of the three kinds of kudingcha 〔young shoots from Ligustrum henryi Hemsl., young shoots and mature leaves from L. robustrum (Roxb.) Bl.〕 were extracted with simultaneous steam distillation extract...The volatile oils of the three kinds of kudingcha 〔young shoots from Ligustrum henryi Hemsl., young shoots and mature leaves from L. robustrum (Roxb.) Bl.〕 were extracted with simultaneous steam distillation extract(SDE) and analyzed and identified by GC-MS. 82 constituents had been identified out of the volatile oils. The major constituents were linalool, alloaromadendrene, gerenial, cedrol, 2-(1,1-dimethylethyl)-phenol, 3,7-dimethyl-1,6-octadien-3-ol, (+)-α-terpineol, γ-elemene, citral and phytol, etc.展开更多
