Hitoegusa (<I>Monostroma latissimum</I> WITTROCK), a kind of greenish seaweed, is widely used as a food, "Nori no tsukuda-ni, " in Japan. The aim of this study was to examine its antioxidative activity and antitumor effect. Hitoegusa was collected at different stages in its life cycle. Strong antioxidative activities were observed in both dichloromethane and methanol extracts of Hitoegusa at several growth stages. Both types of extract obtained from seaweed in January demonstrated especially strong activities. A homogenized suspension of Hitoegusa was intraperitoneally injected into mice implanted with Sarcoma 180. Seaweed collected in March and May seemed to be therapeutically effective against Sarcoma 180, while January weed had no effect.
