Two New Bromophenols from the Red Alga Odonthalia corymbifera
摘要:
Two novel bromophenols (1 and 2) were isolated fi om an extract of a red alga, Odonthalia corymbifera, together with a known bromophenol (3). The novel bromophenols were determined as 4-bromo-2,3-dihydroxy-6-hydroxymethylphenyl 2,5-dibromo-6-hydroxy-3-hydroxymethylphenyl ether (1) and bis(2,3-dibromo-4,5-dihydroxybenzyl) ether (2), from spectroscopic evidence. Compounds 1-3 were found to be inactivators of or-glucosidase.
