Arabinogalactans have been isolated from the tissues of a variety of dicots. However, no arabinogalactan has been isolated from a source known to contain only primary cell walls. The glycosyl compositions of the arabinogalactans isolated from rapeseed cotyledons, rapeseed flour, larch wood, maple sap, the medium of suspension-cultured tobacco cells, the medium of suspension-cultured sycamore cells, and from soybean cotyledons are summarized in Table 2.
