Abstract

Carbon isotopic composition of sterols in marine Holocene sediments, marine sinking particles, tree leaves, and soils were determined. δ13C values of algae-derived sterols such as 24-methylcholesta-5, 22-dien-3β-o1 and dinosterol in the marine sediments range from -22.1 to -25.2‰, while those of 24-ethylcholest-5-en-3β-ol (24-ethylcholesterol) range from -22.6 to -24.3‰. We conclude that 24-ethylcholesterol in the marine sediments derives from marine algae, because their δ13C values are markedly different from those of the leaves of C3 (∼-29‰) and C4 (-14‰) plants and similar to those of the algal sterols.
