Long‐chain ω‐(o‐alkylphenyl)alkanoic acids (APAAs) derived from the heating of unsaturated fatty acids have been widely used for the identification of aquatic products in archaeological ceramic vessels. To date, little attention has been paid to the diagnostic potential of shorter chain (< C₂₀) APAAs, despite their frequent occurrence. Here, a range of laboratory and field experiments and analyses of archaeological samples were undertaken to investigate whether APAAs could be used to further differentiate different commodities. The results provide new insights about the conditions for the formation of APAAs and enable the proposition of novel criteria to distinguish different natural products.

古陶器中ω-(邻烷基苯基)链烷酸的形成及其诊断价值的研究


由不饱和脂肪酸加热产生的长链ω- (邻烷基苯基)链烷酸(APAA)已广泛用于考古陶瓷器皿中水产品的鉴定。迄今为止，尽管短链 (< C ₂₀ ) APAA 频繁出现，但其诊断潜力却很少受到关注。在这里，我们进行了一系列实验室和现场实验以及对考古样本的分析，以研究 APAA 是否可以用于进一步区分不同的商品。研究结果提供了有关 APAA 形成条件的新见解，并提出了区分不同天然产物的新标准。
