Abstract | dc.description.abstract | Meroditerpenoids, 2-[20(E)-30,70,110,150-tetramethylhexadec-2-en-10-yl]-6-methyl-1,4-benzohydroquinone
diacetate and 40-chlorostypotriol triacetate, along with eight known compounds isolated from
the dichloromethane extract of the brown alga Stypopodium flabelliforme after peracetylation are
reported. One of them, 2-(1-oxo-hexadecyl)-1,3,5-trihydroxybenzene, is described for the first time
within this genus. Structural elucidation was carried out on the basis of spectroscopic data and theoretical
studies using GIAO/DFT analysis at B3LYP/6-31G(d) and mPW1PW91/6-31G(d) levels of theory for 40-
chlorostypotriol. This isomer is the first metabolite from the Stypopodium genus possessing one halogen
atom. | es_CL |
