Trimethylsilyl derivatives of 1-hexadecyl-2-decanoyl-, -hexadecanoyl- and -octadecenoyglycerols and 1-octadecyl-2-decanoyl-, hexadecanoyl- and -octadecenoylglycerols as well as 1,2-dihexadecanoylglycerol were analysed by a gas chromatography mass spectrometer system. The following points are characteristic of the fragmentation pattern of these 1-alkyl-2-acyl derivatives: (1) in the spectra of alkyl acyl derivatives, ions at [M -15]+ and [M - 90A1+. are 14 mass units less than those of the corresponding diacyl derivatives; (2) the base peak is m/e 130; (3) alkyl acyl derivatives show fragments due to one acyl group instead of the two acyl groups of diacyl derivatives; (4) ions at m/e 314 and 342, [R1O + 73]+., are characteristic of the trimethylsilyl derivatives of hexadecyl- and octadecylglycerols, respecitvely; (5) the ion [M -R1O]+ is present, but the complementary alkoxy ion is absent.
采用气相色谱 - 质谱联用系统对1 - 十六烷基 - 2 - 癸酰基甘油、1 - 十六烷基 - 2 - 十六酰基甘油、1 - 十六烷基 - 2 - 十八烯酰基甘油、1 - 十八烷基 - 2 - 癸酰基甘油、1 - 十八烷基 - 2 - 十六酰基甘油、1 - 十八烷基 - 2 - 十八烯酰基甘油以及1,2 - 二 - 十六酰基甘油的三甲基硅烷基衍生物进行了分析。以下几点是这些1 - 烷基 - 2 - 酰基衍生物裂解模式的特征：（1）在烷基酰基衍生物的质谱图中，[M - 15]+和[M - 90A1+.处的离子比相应的二酰基衍生物的离子小14个质量单位；（2）基峰为m/e 130；（3）烷基酰基衍生物显示出由于一个酰基产生的碎片，而不是二酰基衍生物的两个酰基产生的碎片；（4）m/e 314和342处的离子，即[R1O + 73]+.，分别是十六烷基甘油和十八烷基甘油的三甲基硅烷基衍生物的特征离子；（5）离子[M - R1O]+存在，但互补的烷氧基离子不存在。
