Abstract: | Summary The occurrence of layers of wood material beneath the soil of the fossil forest of Dunarobba (Italy) has provided the opportunity to study a differently degraded wood formed in the same environment of the fossil forest. The samples of subsoil have almost completely lost their polyose and cellulose fractions and, moreover, were deprived of most of their low and medium MW terpenes so that some phenolic diterpenes were revealed. The identified ones were ferruginol, podocarpodiol, traces of sugiol and a compound whose mass spectrum shows some similarities with that of sugiol. A family of compounds with ketonic structure was also detected: in particular tridecanone, pentadecanone and heptadecanone.Dr. G. Scarascia Mugnozza and Dr. Francesca Bozzano are thanked for fossils donation and Prof. Pasquale Miraglino for mass spectrometry analyses |
