本研究考察了从进口迦南双耳瓶和当地生产的碗从第18王朝的告诉elAmarna，埃及网站的碎片的内表面的沉积物。考古证据表明，迦南人的双耳瓶是用来运输树脂的，而碗则与燃烧树脂作为熏香有关。一些特征性的三萜类化合物鉴定了两种容器类型的所有沉积物为阿月浑子属。没有观察到其他树脂，也没有与油或脂肪混合的证据。考古树脂的组成比现代阿月浑子树脂的组成更复杂，这是由于降解和新组分的产生。实验加热改变现代阿月浑子树脂的三萜类化合物的相对丰度。一种成分，三萜类化合物28-降冰片-17-烯-3-酮，是由这种加热产生的;然而，在古代样品中其相对丰度的增加与加热的考古证据不匹配。因此，不可能可靠地使用该组件来识别加热的树脂。然而，在m/z 453处具有质谱基峰的其他未鉴别组分与7个（共10个）碗相关，并且在与Canaanite amphorae相关的树脂中未观察到。有人提出，这些成分是更可靠的加热分子指标。
This study examines resinous deposits from the interior surfaces of sherds of imported Canaanite amphorae and locally produced bowls from the 18th Dynasty site of Tell elAmarna, Egypt. Archaeological evidence indicates that the Canaanite amphorae were used for resin transport, whilst the bowls are associated with burning resin as incense. A number of characteristic triterpenoids identify all the resinous deposits from both vessel types as Pistacia spp. No other resins were observed and there was no evidence of mixing with oils or fats. The composition of the archaeological resins is more complex than that of modern pistacia resin, due to degradation and generation of new components. Experimental heating alters the relative abundance of the triterpenoid composition of modern pistacia resin. One component, the triterpenoid 28-norolean-17-en-3-one, is produced by such heating; however, an increase in its relative abundance in ancient samples is not matched by the archaeological evidence for heating. It is therefore not possible to use this component reliably to identify heated resin. However, additional unidentified components with a mass spectral base peak at m/z 453 have been associated with seven (out of 10) bowls and are not observed in resins associated with Canaanite amphorae. It is proposed that these components are more reliable molecular indicators of heating.
