Ambers from Peñacerrada (Basque Country, North Spain) have been analysed by IR spectroscopy and GC-MS in order to study the polymeric and solvent-soluble GC-amenable fractions, respectively. All samples showed branched monoalkybenzenes, bicyclic sesquiterpenoids and tricyclic diterpenoids related to pimaric acids precursors, suggesting a paleobotanic origin… CONTINUE READING
