This paper reports mass spectra and linear temperature programmed retention indices (I(T)) for 31 esters of mono- and sesquiterpene alcohols with hydroxycinnamic acids. In this study, 14 phenylpropenoids were synthesized by esterification of terpenols with p-coumaric, ferulic, caffeic and sinapinic acids. Other phenylpropenoids were semi-quantitatively isolated by column chromatography from exudates covering the buds of two birch species (Betula pubescens and B. litwinowii). Main diagnostic ions in phenylpropenoids mass spectra were determined by GC/MS analysis. The possibility of predicting I(T) values was demonstrated with standard error of prediction between 3 and 11 of retention index units.
本文报道了31种单萜和倍半萜醇与羟基肉桂酸形成的酯的质谱图和线性程序升温保留指数（I(T)）。在本研究中，通过萜醇与对香豆酸、阿魏酸、咖啡酸和芥子酸的酯化反应合成了14种苯丙素类化合物。其他苯丙素类化合物通过柱色谱法从两种桦树（毛桦和利特维诺夫桦）芽的渗出物中半定量分离得到。通过气相色谱/质谱分析确定了苯丙素类化合物质谱中的主要诊断离子。预测I(T)值的可能性得到了证明，预测标准误差在保留指数单位的3到11之间。
