Abstract;Flavonoids and related compounds were known to have the activity to affect lipid oxidation, DNA oxidation, and so on. There are many reports available to tell us the content of flavonoids in vegetables and fruits; however the content of flavonoids in seaweed is not yet available. In this study, the total amounts of rutin, quercitrin, hesperidin, myricetin, morin, luteolin, quercetin, apigenin, kaempferol, baicalein, caffeic acid and catechol in 27 Japanese seaweeds were analyzed by HPLC after hydrolysis. They were separated by an ODS-column and identified with diode array spectra. Quercetin, apigenin, kaempferol, and baicalein were not detected in all seaweeds. Hesperidin was found in all of red algae, at the amount 626-119000 .MU.g/g dry matter. Catechol was detected all of red and green algae at the amount 1660-77700 .MU.g/g dry matter, and the highest amount was found in Caulerpa serrulata. Morin was detected from all samples, and the highest amount was 3730 .MU.g/g dry matter in Caulerpa serrulata. Quercitrin and myricetin were determined only from 2 seaweeds, at the amount of 202-466, and 270-346 .MU.g/g dry matter, respectively. In general, red algae had larger amount of these compounds analyzed in this experiment than brown and green algae. (author abst.)
