Superoxide dismutase activity enhanced by green tea inhibits lipid accumulation in 3T3‐L1 cells

We studied the effect of powdered green tea on intracellular superoxide dismutase activity in the adipose conversion of 3T3-L1 cells. By the 14 days of culture with insulin, the triglyceride concentration was increased. When powdered green tea and insulin were added simultaneously, the increased triglyceride content was decreased (p < 0.05), and the superoxide dismutase activities were significantly enhanced (p < 0.05). These data suggest that green tea may have an antilipogenic activity due to its radical scavenging activity mechanism.
