An anti-complementary arabinogalactan (AGIIb-1), isolated from the roots of Angelica acutiloba Kitagawa, comprised one neutral (N-I) and two acidic arabinogalactan (A-I and A-II) units and one neutral arabinan unit (N-II). N-I showed the most potent anti-complementary activity. AGIIb-1, A-I, and A-I

Four pectic polysaccharides (AR-2IIa-IId) with anti-complementary activity have been isolated from a hot-water extract of the root of Angelica acutiloba Kitagawa. Each of these polysaccharides contained a large proportion of GalA together with neutral sugars consisting mainly of Rha, Ara, and Gal. D

The endo-a-(1--3-4)-polygalacturonase-resistant regions (PG-la-1c) from three anti-complementary acidic polysaccharides (AR-211a-He), isolated from the root of Angelica acutiloba Kitagawa, were subjected to base-catalysed ,S-elimination in the presence of sodium borodeuteride . Each PG-l gave a neut
