[Background]
Marine algae baths, especially kajime group (Ecklonia and Eicenia) algae baths, have traditionally been used in coastal areas in Japan. Kajime algae have high content of minerals and polyphenols, and it is promising as a material for functional foods. These functional compounds are thought to be effective also in the marine algae baths, but they have not been clear. Therefore, in this study, to clarify the functional properties, the following experiments were conducted.
[Methods]
From the literature and web information, the local situation the usage methods of marine algae bath were checked. Effects of hot water extract solution (WE) from dried product of “arame” Eisenia bicyclis on hand surface (epidermic) viable counts, skin moisture and their antioxidant properties were determined.
[Results]
There are baths with kajime group algae are popular in Chiba, Ibaraki, Mie and Ishikawa prefectures. In the Pacific Ocean side, E. bicyclis is used for the kajime bath. Although the effects of E. bicyclis WE on the viscosity, the antibacterial at hand skin, and the skin moisture were not remarkable, the antioxidant property, particularly the superoxide anion (O2-) radical scavenging capacity was remarkable.
[Conclusion]
O2-radical is the reactive oxygen that occurs first in body. Therefore, it is considered that O2-radical scavenging capacity can inhibit other strong reactive oxygens generated from O2-in body. Further study is necessary to examine the effects of the antioxidant properties of E. bicyclis bath on the skin and whole body health.
