Abstract
The contents of carotene and vitamin C in the fresh seaweed samples of 58 species (7 green seaweeds, 23 red seaweeds and 28 brown seaweeds), which were collected at the sea shore of Katsurashima, Shimane Prefecture or Kumihama, Kyoto Prefecture, were determined.
The results are as follows : (1) It was found that the content of carotene in 100 g of the fresh seaweed samples of 51 species was above 600 pg and that of vitamin C was above 20 mg in 100 g of the samples of 39 species. (2) The relationships between the carotene and the vitamin C contents in seaweed samples varied with the species of seaweeds. For example, positive correlations were observed in green and red seaweeds, but not in brown ones.
