“…This could arise from subtle taxonomic shifts in vegetation type, which can change the leaf waxes and associated ratios significantly (Eglinton and Hamilton, 1967;Herbin and Robins, 1969;Holloway and Baker, 1970;Lytle et al, 1976). However, the plant biomarkers represented by the three ratios are rather physiologically diverse.…”

However, the two records differ in detail and the regional nature of the Dongge palaeoprecipitation signal has therefore been questioned.Our study re-evaluates both records by constructing, for the same estuarine core, biomarker and compound-specific δ 13 C records, which have better constrained terrestrial and marine end members than  13 C org , providing additional insights into the evolution of the Asian SummerMonsoon.The Branched Isoprenoidal Tetraether (BIT) index reflects the ratio of soil versus marine organic matter. The BIT record from the estuarine core co-varies with the Dongge Cave  18 O record suggesting the two share a common control which is likely to be driven by regional climate. By contrast, the sterols, n-alcohols and n-fatty acid ratios show the same overall trend as Dongge, but parallel the  13 C org record's variability between 6.5-2 kyrs indicating a partial decoupling between soil and land-plant organic matter fluxes in the Pearl River Basin.There is clear divergence between the biomarker and 13 C org records from 2 kyrs to present.Analysis of the leaf wax δ

“…However, high amounts of straight chain n-alkenes have been reported in plants such as sugar cane (SORM et al, 1964), roses (MLADENOVA et al, 1983), and ferns (LYTLE et al, 1976). The biosynthetic mechanism involves fatty acid decarboxylation (GORGEN and BOLAND, 1989) which is consistent with the odd to even carbon number predominance The C&C3, n-alkenes present in the Santa Olalla Lagoon are concurrent with other terrigenous components such as the C&& n-alkanes, C&C32 n-alkanoic acids, and polycyclic higher plant markers that will be discussed later.…”

The aqueous ethanol extract of Lygodii Spora (spore of Lygodium japonicum (THUNB.) SW.) showed in vitro testosterone 5a a-reductase inhibitory activity and in vivo anti-androgenic activity using growth of flank organ in castrated Syrian hamsters and hair regrowth after shaving in testosterone-treated C57Black/6CrSlc mice. From the lipophilic constituents of Lygodii Spora, oleic, linoleic and palmitic acids were identified as the main active principles inhibiting testosterone 5a a-reductase.
