摘　　要：海带中含有高浓度的碘是其独特的化学组成特点,历来被海藻学家所重视(Tangand Chang,1935,1936;Black,1948,1949;Klemperer,1957;Fernandez et al.,1964;Dave et al.,1973;Law,1975;Solimabi and Das, 1977;Yamamoto et al.,1984;Doshi and Joshi.,1989;Mairh et al.,1989)。Laminaria japonica was collected from the coast of Qingdao from April to July, 1995. Determination of the iodine contents of different parts in the same sample by an iodine ion-elective electrode showed that iodine was distributed throughout Lam-inaria japonica and could constitute 0.133% of fresh weight. The iodine contents varied greatly within the same sample. The frond was richer in iodine than the stipe, especially in the top of frond, whose contents could reach 0.183% of fresh weight. This distribution characteristics relates to the plant metabolism. The more active metabolism some parts of Laminaria japonica have, the more iodine they accumulate.
