Ceramic vessel 7-22. Cemetery of Cerro de los Vientos (Baeza, Jaén, Spain)

Funerary urn from grave 26 of the cemetery Cerro de los (Baeza, Jaén, Spain). Handmade ceramic vessel, reducing atmosphere. The urn contained the cremated remains of a subadult woman. The lipid content analysis has been performed using GC-MS obtaining a characteristic profile of beeswax: alkanes nC23 to nC31, long chain alcohols C24(OH) to C32(OH) and palmitic acid wax esters W40 to W50.

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.

The analyses were performed using a using a gas chromatography equipment (model Thermo TraceGC Ultra) coupled to a Thermo DC Q II mass spectrometer. Autosampler Thermo Triplus (CICT, University of Jaén). The samples were introduced by on-column injection into a 15 m x 0.25 mm I.D. fused silica capillary column, coated with poly(dimethylsiloxane) stationary phase with 0.1 μm film thickness. Helium was used as the carrier gas (purity 99.99%).
