It was observed that the hot-water extract of the bark of Kalopanax pictus N. had the highest anti-complementary activity among the 11 kinds of forest materials. Methanol-and ethanol-soluble portions had low anti-complementary activities, but crude polysaccharide. HKP-0 had a high activity of 80%. HKP-0 contained 54.8% of total sugar and 27.9% of protein. The neutral sugars of HKP-0 consisted of mainly arabinose, galactose and glucose. HKP-4 fraction obtained by cetavlon treatment of HKP-0 showed the highest anti-complementary activity of 90%. The activity was not changed by pronase digestion bu decreased greatly by periodate oxidation. HKP-4 consisted of mainly arabinose and glucose with molar ratio of 1.0 : 22.4, HKP-4-I, an unabsorbed fraction from HKP-4 on DEAE Sepharose CL-6B column showed higher yield and activity than those of absorbed fractions. HKP-4-I was homogeneous, and its molecular weight was about 25,000. HKP-4-I contained 84.0% of neutral sugar and consisted of arabinose and glucose with molar ratio of 1.0 : 11.2. The anti-complementary activity of HKP-4-I was not decreased by the treatment of polymyxin B, and the polysaccharide activated both classical and alternative pathway in complement system. Void volume fraction obtained from HKP-4-I hydrolyzed with ${\alpha}$-amylase on Sephadex G-25 column only had a high anti-complementary activity.
