摘要
采用超临界CO2萃取结合气相色谱-质谱联用仪(GC-MS)分析重庆产速生金桂和朱砂丹桂挥发油的组成成分差异。从金桂和丹桂挥发油中分别鉴定出36和34种化合物,其中有17种共有组分,36种非共有组分。醇类及其氧化物是金桂和丹桂挥发油的主要成分,分别占2种桂花挥发油百分含量的82.36%和87.88%。其次为酮类,分别占2种挥发油的11.06%和5.78%。金桂挥发油中含量较高的化合物为对羟基苯乙醇(27.02%)、(E)-呋喃芳樟醇氧化物(26.46%)和2,6-二甲基2,7-辛二烯-1,6-二醇(15.06%)。丹桂挥发油中含量较高的化合物为顺-α,α-5-三甲基-5-乙烯基四氢化呋喃-2-甲醇(51.02%)、对羟基苯乙醇(14.95%)和2,6-二甲基2,7-辛二烯-1,6-二醇(10.70%)。与朱砂丹桂相比,速生金桂中活性物质含量较高,具有较高的研究价值。
Essential oil was extracted from Osmamthus fragrans Sushengjingui and ＇ Zhushadan＇ （Chongqing） with supercritical CO2. The essential oil was analyzed to research the chemical composition by Gas Chromatography and Mass Spectrometry （ GC - MS）. A total of 36 and 34 chemical constituents were identified from O. fragrans Sushengjingui and Zhushadan respectively. The major compositions were alcohol and its oxide （82.36% in Sushengjingui and 87.88% in Zhushadan）, and then ketones （ 11.06% and 5.78% ）. The major constituents of Sushengjingui were 4 - hydroxyphenethyl alcohol （27.02%）, （E） - furanoid linalool oxide （26.46%） and 2, 6 - dimethyl -2, 7 - octadiene - 1, 6 - diol （ 15.06% ）. The major constituents of Zhushadan were 5 - ethenyltetrahydro - α, α - 5 - trimethyl - cis - 2 - furanmethanol （51.02%）, 4 - hydroxyphenethyl alcohol （ 14.95% ） and 2, 6 - dimethyl - 2, 7 - octadiene - 1, 6 - diol （ 10.70% ）. Due to its high content of physiological activators, Sushengjingui had greater research values compared with Zhushadan.
