The crude hemicelluloses, isolated from stems of Mahonia aquifolium, on ion-exchange and gel chromatography gave an acidic polysaccharide (AP) which eluted as a broad band in high-pressure gel-permeation chromatography. The average apparent molecular mass (M app ) was determined to be 5.8 kDa. Compositional and linkage analyses, supported by 1D and 2D NMR spectroscopy measurements...
The purpose of this study was to isolate and perform chemical analyzes as well as biological testing of pectic material from white cabbage isolated by sequential aqueous ionic solutions (SEQAIS) or a simple pure water extraction (PW). Water extraction was aimed at yielding water-soluble pectins only, while the harsher conditions in SEQAIS aimed at extracting proto pectin as well. The pectic material...
