“…No previous studies of fossil seeds have used THM (McCobb et al, 2001;Stankiewicz et al, 1997;van Bergen et al, 1994a, b;1997a, b). For phenolic polymers such as lignin, it has been shown that the products from THM are in better agreement with the molecular structure of lignin than those from conventional pyrolysis (Challinor, 1995(Challinor, , 2001). The phenolics and sugar product from the Juncus seed coats may relate to the lignin/cellulose complex observed in previous studies (van Bergen et al, 1994a, b;Graven et al, 1996Graven et al, , 1997van Bergen et al, 1997a, b;Stankiewicz et al, 1997;McCobb et al, 2001).…”

“…The main compounds identified, together with their relative abundance, are listed in Table 3. Previous studies [23,24,25,26,27,28,10] showed that TMAH thermochemolysates of lignin comprise methyl esters of aromatic carboxylic acids, in addition to the methylated counterparts of the compounds generated upon conventional pyrolyses. These thermochemolysates thus contain numerous methoxybenzenes substituted by remnants of the original C 3 side-chain of lignin units, bearing various oxygenated functions (aldehydes, ketones, methoxy and carboxylic acid methyl esters).…”

“…Hardell and Nilvebrant (1996) report 1-veratrylglycerol trimethyl ethers, obtained from β-ether linked units, as the main degradation products formed from lignins by THM, and the identification of such peaks also in the present experiment verified the lignin origin (β-O-4 ether bonds) of the investigated samples. The THM pyrograms also indicated that the proportion of carboxylic acids, detected as methyl esters (Hardell and Nilvebrant 1996;Challinor 1995;Martin et al 1995), was higher in the FTE and sludge lignin samples than in the PTE lignin. This indicates that the biological treatment increases the amount of compounds containing carboxylic acids groups, by means of oxidation reactions.…”
