Abstract
The seasonal and portional variation in the composition of uronic acid of alginic acid from Eckionia cava was investigated. The sample was collected from the coast of Ieechun Illkwangmyun, Yangsangun, Kyungnam, Korea, in the period of January to December in 1982. In seasonal variation of the content of alginic acid, the range of variation was larger in the frond than in the stipe, It was the highest content in between February to April, and the lowest in between August to October, and the content was more in the stipe than in the frond. The uronic acid ratio(M/G ratio) was varied seasonaly in a relationship with the variation of the alginic acid content. The maximum M/G ratio appeared in the period of December to March and minimum May to August, and the average values of the M/G ratios in the periods were 3.08, 2.64 in the frond and 2.91, 1.39 in the stipe, respectively. Additively a year mean values were 3.22 in the frond and 2.18 in the stipe.
