用气相色谱一质谱联用法分析了肿节风挥发油的化学成分，鉴定了其中38个化合物，占挥发油色谱峰总面积的72％，主要成分为榄香烯（14．41％），1-对-烯-8-乙酸酯（13．71％），雅槛蓝烯（8．55％）及β-罗勒烯-X（6．88％）。
The chemical constituents of the volatile oil of Sargassum were analyzed by gas chromatography-mass spectrometry. Among them, 38 compounds were identified, accounting for 72% of the total peak area of the volatile oil. The main component was Elemene (14.41%), 1-pair. -Alkene-8-acetate (13.71%), acetylene blue (8.55%) and β-ocimene-X (6.88%).
