Vessel 119. Grave 231. Cemetery of La Noria (Fuente de Piedra, Málaga, Spain)

Plate. Grave 231 of burial mound H of the Iberian cemetery of La Noria (Fuente de Piedra, Málaga, Spain). Handmade pottery, oxidising atmosphere. It has no decoration. The analysis of lipid contents was carried out using GC-MS and HPLC-APCI-MS, obtaining a characteristic lipid profile of ruminant animal fat.

The interpretation is based on the identification of a set of chemical markers obtained after the joint application of these two techniques: volatile or short-chain fatty acids (C12: 0 and C14: 0), fatty acids with number odd carbon atoms and their corresponding chain isomers (C15: 0, i-C15: 0, C17: 0, i-C17: 0), positional isomer of oleic acid (i-C18: 1), where unsaturation (double bond) presents a different position in the hydrocarbon chain, TAGs formed mainly by saturated fatty acids (myristic: M, palmitic: P, stearic: S). The analysis by HPLC-APCI-MS determines a P/S index in sn-2 position of 55/45, indicative of ruminant animal fats.

Pottery. Lipids analysis

Destructive method for the identification of the total lipid profile: fatty acids, sterols, wax esters, fatty alcohols, triacylglycerols, etc. Any remains of soil were removed with an electric hand-drill. The sample was then grinded to the appropriate size in an agatha mortar (0.25 mm). Extraction with a the mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization of lipids to trimethylsilyl derivatives (TMS). The reaction tales place at 70 ºC for 30 min using N,O-bis-(trimethylsilyl) trifluoroacetamide (BSTFA) with 1 % trimethylchlorosilane (TMCS). The sample is solved in cyclohexane and then injected in GC-MS. Chromatographic separation is performed applying an adequate temperature programme.

High Performance Liquid Chromatography-Mass Spectrometry

Pottery. Triacylglycerols analysis

Destructive method for the identification of TAGs content. Any remains of soil were removed with an electric hand-drill. The sample was then grinded to the appropriate size in an agatha mortar (0.25 mm). Extraction with a the mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization is no needed. Lipid extract is solved in isopropanol and then injected in HPLC-APCI-MS. Chromatographic separation is performed applying an adequate mobile phase gradient (mixture of isopropanol and methanol).
