Sažetak
From the flowers of Calendula officinalis, three homogeneous polysaccharides were isolated by ethanol fractionation and gel filtration. Sugar and methylation analysis showed that all three polysaccharides contain a (1->3)-linked B-D-galactan backbone with branching points at C-6. The side chains, are composed of short A-Araf(1->3)-Araf, A-L-Rhap-(1->3)-Araf or simple A-L-Araf units. Further characterization of the polysaccharides was performed by periodate oxidation and Smith degradation, acid hydrolysis and various 13CNMR spectroscopic methods. The polysaccharides showed immunostimulating activity in several in vitro immunological test systems.
