Resinous deposits from the inner walls of Roman age amphorae have been analysed by GC-MS. A simple dissolution of the sample in chloroform was carried out without any previous treatment of the sample. A new method for derivatization of carboxylic groups in these type of compounds was tested using methylchloroformate (MCF) in the optima conditions, giving good results with a short derivatization time. Some diterpenoid components of conifer resin have been identified, as well as other monoterpenoid components of essential oils. Results obtained allowed to know the nature and origin of these resinous deposits and the early Roman age technological practices in Spain.
罗马时代双耳细颈椭圆土罐内壁的树脂沉积物已通过气相色谱-质谱联用仪进行了分析。在对样品未进行任何预处理的情况下，将其简单溶解于氯仿中。使用氯甲酸甲酯（MCF）在最佳条件下测试了一种用于这些类型化合物中羧基衍生化的新方法，衍生化时间短且效果良好。已鉴定出针叶树树脂的一些二萜类成分以及精油的其他单萜类成分。所得结果有助于了解这些树脂沉积物的性质和来源以及西班牙罗马时代早期的工艺实践。
