Abstract
The structure of the major component contained in a liquid seaweed ext ract prepared from Ascophyllum nodosum (Phaeophyta, Fucales) was inves tigated. The extract was fractionated by gel permeation chromatography , and the various fractions were analysed by GLC, HPLC, C-13 NMR spect roscopy and mass spectrometry. All fractions were derivatives of the b ranched beta-D-(1 --> 3) glucan known as laminaran. They were capable of eliciting D-glycanase activities (laminaranase, alpha-amylase) in R ubus fruticosus suspended-cell cultures.
