气相色谱-质谱联用分析晚香玉净油的成分

The Analysis of the Chemical Constituents of Absolute Oil of Tuberose by GC-MS

本文对云南产的单瓣晚香玉和重瓣晚香玉提取净油,并运用气相色谱-质谱法(GC-MS)分析成分及含量。结合评香结果,研究单瓣晚香玉和重瓣晚香玉净油成分的差异性。结果表明:两个品种的晚香玉主成分是:alpha-松油醇、邻氨基苯甲酸甲酯、异丁香酚甲醚、金合欢醇、苯甲酸苄酯、水杨酸苄酯等。单瓣晚香玉净油的主香成分含量较高,如:单瓣晚香玉净油的alpha-松油醇、邻氨基苯甲酸甲酯、金合欢醇、苯甲酸苄酯的含量分别为3.679%、11.564%、13.263%、39.785%;重瓣晚香玉净油的alpha-松油醇、邻氨基苯甲酸甲酯、金合欢醇、苯甲酸苄酯的含量分别为2.706%、6.038%、6.394%、26.005%。重瓣晚香玉浸膏、净油得率较高。

To analysis the chemical constituents of absolute oil from two varieties of Tuberose in Yunnan provice by GC-MS. Comparing the difference of the chemical constituents between unipetalous Tuberose and polyphyll Tuberose, combineing the sensory evaluation.The dates show that the main compounds include： 3-Cyclohexene-l-methanol, trimethyl-, Benzoic acid, 2-amino-, methyl ester, Benzene, 1,2-dimethoxy-4-（1-propenyl）-, 2,6,10-Dodecatrien-l-ol, 3,7,11-trimethyl-, （E,E）-, BenzylBenzoate, Benzoic acid, 2-hydroxy-, phenylmethyl ester,ect. The contents of main constituents of absolute oil of unipetalous Tuberose are higher than the contents of main constituents of absolute oil of polyphyll Tuberos.For example： the contnets of 3-Cyclohexene-l-methanol, trimethyl-, Benzoic acid, 2-amino-, methyl ester, 2,6,10-Dodecatrien-l-ol, 3,7,11-trimethyl-, （E,E）-, BenzylBenzoate of unipetalous Tuberose are 3.679%, 11.564%, 13.263%, 39.785%; in the contrast polyphyll Tuberose are 2.706%, 6.038%, 6.394%, 26.005%. The extraction rate of polyphyll Tuberose is higher than unipetalous Tuberose.
