“…The final diterpenes are stable and lasting compounds, having been found as residual terpenes in fossils older than 65 million years from the Canadian Arctic (Staccioli et al 1998). In contrast, as far as the disproportion products are concerned, only dehydroabietic acid has been found in sub-fossil samples, thus tetrahydroabietic acid must be searched for in fossils from the earliest steps of diagenesis.…”

Fossil samples of Pinus sylvestris found near Siena (Tuscany, Italy) in geological formations 2-3 million years old were chemically examined in order to solve the problem of the contrast between the age of geological formations and their good degree of preservation.Comparison with a living Pinus sylvestris was carried out on standard wood component analyses, cation exchange capacity and residual terpene content. The analyses of wood components were close to those of the reference pine, whilst the cation exchange capacity values showed remarkable changes. The increase of salt carboxyls suggested the hydrolysis of ester carboxyls originally present, whilst the reduction of total carboxyls revealed a partial loss of hemicelluloses. Both changes were attributed to the percolation of salt-bearing water through the wood, thus causing ester hydrolysis, carboxyl salification and hemicellulose solubilisation. Residual terpene analysis showed, for the first time in a

“…Beside the standard microanatomical approach for identification of fossil woods, chemical determinations of fossil woods by GC-MS analyses of their solvent extracts represent a traditional and successful characterization (Grantham and Douglas, 1980;Laver and Fang, 1986;Obst et al, 1989;Zavarin and Cool, 1991;Staccioli et al, 1993;Menchi et al, 1997;Otto et al, 1997;Staccioli and Bartolini, 1997;Nagahama et al, 1998;Staccioli et al, 1998aStaccioli et al, -c, 2002. As further alternative, thermal breaking of large molecules into smaller pyrofragments has extended the use of GC-MS to polymeric materials including natural polymers.…”

“…Therefore, in the present paper, an anatomical and chemical study was attempted in terms of one conifer bogwood piece obtained from the salvaged wood. The chemical analysis of volatile components may also give information on their diagenetic changes, based on previous studies (Simoneit et al 1986 ;Staccioli et al 1993Staccioli et al , 1997Staccioli et al , 1998Staccioli et al , 2000Menchi et al 1995 ;Otto and Simoneit 2002 ;Narita et al , 2007Narita and Kuga 2009 ). For comparison of anatomical and chemical features, several fresh pine samples were collected and analyzed.…”

Chemotaxonomical identification of Holocenic bogwood recovered after 2007 Niigataken Chuestsu-oki Earthquake

A Holocenic coniferous bogwood salvaged from the 70 to 100 m-deep seabed after the 2007 Niigataken Chuetsu-oki Earthquake was analyzed anatomically and chemically. The main anatomical features of the wood were the presence of (i) large window-like pits in cross fi eld and (ii) smoothwalled cells of ray tracheid. Feature (i) allowed identifi cation of the wood as genus Pinus . Feature (ii) is characteristic of section Quinquefoliae , but possible decay by the long burial (3400 -3210 cal BP) left the identifi cation inconclusive. Chemical analysis showed that the major volatile components of the bogwood were cadinane-type sesquiterpenes. In contrast, those of modern pine samples were longifolene and monoterpenes from Pinus densifl ora and Pinus thunbergii , nerolidol from Pinus parvifl ora and P . parvifl ora var. pentaphylla , and monoterpenes from Pinus koraiensis . Thus, none of the modern pines contained cadinane-type sesquiterpenes as major components. As organic components of wood are known to undergo diagenetic transformation under geological conditions, recent samples were subjected to heat treatment at 180 ° C for 24 h to simulate the long burial time. As a result, nerolidol, the main component of P . parvifl ora and P . parvifl ora var. pentaphylla was converted to cadinane-type sesquiterpenes. Therefore, it is highly likely that the bogwood sample was P . parvifl ora or P . parvifl ora var. pentaphylla , section Quinquefoliae subsection Strobus , agreeing with the anatomical feature of section Quinquefoliae .
