The changing regulation of the content and compositions of essential oil of Santolina chamaecyparissus L.during florescence was studied,which was grown in Shanghai Chongming Island.Steam distillation was used to extract the essential oil from S.chamaecyparissus,while GC and GC-MS were used to analyze the composition of the oil.The result indicated that the average content of the oil of S.chamaecyparissus was 1.45,2.05,1.38 mL·kg-1(FW) in the preliminary florescence,flourishing florescence and terminal florescence respectively,and the content reached peak in the flourishing florescence.The essential oil was identified to be composed of 25 kinds of substance,most of which were ketones,terpenes and alcohols.The main components of the essential oil were Artemisia ketone(19.39%~24.02%),Vulgarone(16.16%~22.23%),Myrcene(9.00%~12.11%),β-phellandrene(13.56%~18.08%),Sabinene(3.50%~4.78%)and β-pinene(3.58%~4.07%).The composition of the essential oil had no remarkable changes during the whole florescence,while the content ration of each component changed evidently.
