✦ Synopsis
The carbohydrates of the fruit of the wild Siberian apricot have been studied in relation to dietary fibre composition and potential uses in food and in the pharmaceutical industry'. Previous studies dealt with the isolation, purification, and characterisation of hemicelluloses from the delignified cell-wall material of the apricot2y3. We now report on the structures of two pectic polysaccharides.

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
Rhamnogalacturonan I (RG-I), a pectic polysaccharide isolated from the walls of suspension-cultured sycamore cells, was shown by glycosyl-residue composition analysis to contain D-glucosyluronic acid (GlcpA) residues (1 mol%) and 4-O-methyl-D-glucosyluronic acid (4-O-Me-GlcpA) residues (0.5 mol%). T
