Ceramic vessel 139. Grave 231. Cemetery of La Noria (Fuente de Piedra, Málaga, Spain)

Bowl. Grave 231 of burial mound H of the Iberian cemetery of La Noria (Fuente de Piedra, Málaga, Spain). Wheelmade pottery, oxidising firing. It has no decoration. The analysis of lipid contents has been performed using GC-MS and HPLC-APCI-MS. The chemical indicators identified by the joint use of these two techniques show a mixture of ruminant, non-ruminant animal fat and beeswax.

The chemical markres of beeswax identified are: odd-chain alkanes (nC27-nC31), fatty alcohols [C24 (OH) -C30 (OH)] and esters of palmitic acid waxes (W40 -W48).

In the case of animal fat, the profile of TAGs obtained by HPLC-APCI-MS shows the presence of a mixture of ruminant fat (highly saturated TAGs SSP, PPS, SSS), with non-ruminant (abundant TAGs, formed mainly by oleic and palmitic acids PPO, OOP, PPP, with a higher concentration of the latter compared to ruminant fat). The study by HPLC-APCI-MS determines a P/S ratio in sn-2 position of 73/27. This intermediate value would confirm the mix of both types of fats.

Gass Chromatography-Mass Spectrometry

Pottery. Contents 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 mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization of lipids to trimethylsilyl derivatives (TMS). The reaction takes place at 70 ° C 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 a adequate temperature program.

Pottery. Contents 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 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 a adequate mobile phase gradient (mixture of isopropanol and methanol).
