摘要: Dihydrophytol(3,7,11,15-tetramethylhexadecanol) was identified in the nonsaponified lipid fraction of fecal pellets from copepod Calanus helgolandicus fed laboratory on a unialgal diet. Direct deposition certain zooplankton species may explain presence dihydrophytol marine sediments. Microbial reduction phytol sediment cores does not account for origin this compound all sedimentary environments.
