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

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
