通过将千层塔挥发油经气相色谱-质谱法(GC/MS)分析,首次研究其化学成分.结果表明:千层塔挥发油成分复杂,含量较高的为3-羟基-2-甲基戊二酸二甲酯、苹果酸二甲酯、3-羟基-正丁酸甲酯、3-(4-羟苯基)-2-丙烯酸甲酯与4-羟基-α,α,4-三甲基-环己甲醇.此外,还鉴别到一种石松生物碱.千层塔挥发油中分子量较小的酯类与醇类物质较多,并含有一种生物碱Luciduline. The chemical constituents were first studied by gas chromatography-mass spectrometry (GC / MS) analysis of the essential oil of Melaleuca tower.The results showed that the constituents of the volatile oil of Melaleuca tower were complex and the contents of 3-hydroxy-2- Dimethyl malate, methyl 3-hydroxy-n-butyrate, methyl 3- (4-hydroxyphenyl) -2-propenoate with 4- hydroxy-alpha, alpha, -cyclohexylmethanol.An addition, a stomatal alkaloid was also identified.Microlacta volatile oil esters and alcohols with smaller molecular weight, and contains an alkaloid Luciduline.
