This paper is devoted to the examination of two specimens of Naga-kombu, Laminaria longissima, which after two years of growth were harvested in June and August at Kushiro, Hokkaido.
The base, central and top parts of the blade in each specimen were dried and powdered, and analyzed for the determination of the general components. The experimental values are shown in Tables 1-4, and the results obtained are summarized as follows.
The contents of crude protein and fat in Sei-kombu, mature L. longissima, were relatively high as compared with other tangle species.
The contents of crude protein and ash were higher in Saomae-kombu, immature L. longissima, and those of fat and glucide were lower than in Sei-kombu.
The ascus parts of Sei-kombu contained more protein, fat and glucide than its other parts.
The analytical values of Sei-kombu were between those of the ascus parts and the values of the remainder. The variation of the values hitherto reported may be due to the ratio of ascus parts to the remainder in the sample.
