摘　　要：采用气相色谱—质谱联用分析法,分析测定红树植物红海榄胚轴中挥发油和脂肪酸的成分。结果表明,挥发油中分离出29个峰,鉴定出29种化合物,酚类物质有11种,是最多的一类,其总量达到了挥发油总量的47.12%。其中3-甲氧基-1,2-丙二醇含量最为丰富,占挥发油总量的26.39%;另外,还含有对甲基苯酚、橙花叔醇、榄香素等具有芳香气味的中药有效成分化合物。脂肪酸中分离出30个峰,鉴定出26种化合物,其中脂肪酸有8种,占脂肪酸总量的19.55%;十六酸(棕榈酸)、8,11,14-二十碳三烯酸、9,12-十八碳二烯酸(亚油酸)含量比较高,分别占脂肪酸总量的7.59%、4.25%、3.22%。The volatile oil and fatty acids in the hypocotyls of the mangrove plants Rhizophora stylosa were studied by GC-MS. According to the results, 29 peaks were separated and 29 compounds were identified from the volatile oil , there were 11 kinds of polyphenols, a class of the largest, which reached 47.12 % of the total mount of volatile oil. 3-methoxy-1, 2-propanediol was abundant and about 26.39 % of them, many active chemical components of 4-methyl-phenol, nerolidol, elemicin etc. were also involved. And 30 peaks were separated and 26 compounds were identified from the fatty acids, in which there were eight kinds of fatty acids, reached 19.55 96 of fatty acids extraction, the contents of cetylic acid, 8, 11, 14-eicosatrienoic acid and linoleic acid were high, respectively took the proportion of 7.59 %, 4.25 % and 3.22 %.
