Several cyclitol glycosides have been characterised as trimethylsilyl derivatives by their gas chromatographic (GC) retention data (linear retention indices) and electron impact mass spectrometric (MS) profiles. Both GC-MS results have been related to cyclitol glycosides structural features. Abundance ratios of characteristic m/z ions 133/129 and 260/265 have been proposed to distinguish glycosyl-inositols from glycosyl-methyl-inositols. These ratios in combination with the presence or absence of m/z 375 ion allowed the unequivocal characterization of cyclitol glycosides. These criteria have been applied to the characterization of new cyclitol glycosides in chickpea (Cicer arietinum) and adzuki bean (Vigna angularis) and in leaves of Coriaria myrtifolia and Coriaria ruscifolia.
几种环醇糖苷已通过其气相色谱（GC）保留数据（线性保留指数）和电子轰击质谱（MS）图谱表征为三甲基硅烷基衍生物。这两种GC-MS结果均与环醇糖苷的结构特征相关。有人提出特征m/z离子133/129和260/265的丰度比来区分糖基肌醇和糖基甲基肌醇。这些比率与m/z 375离子的存在与否相结合，使得环醇糖苷能够得到明确的表征。这些标准已应用于鹰嘴豆（Cicer arietinum）、小豆（Vigna angularis）以及马桑（Coriaria myrtifolia）和圆叶马桑（Coriaria ruscifolia）叶片中新环醇糖苷的表征。
