ANALYSIS OF HYDROSOLUBLE POLYSACCHARIDES FROM RAMONDA-MYCONI LEAVES

The mucilage of Ramonda myconi leaves is composed of several polysacch arides differing in acidity due to the content of galacturonic acid. R MP-2 and RMP-4 are the most important fractions, where RMP-2 is an ara binogalactan containing galacturonic acid and rhamnose, probably conne cted to a protein moiety. RMP-4 is the major fraction, containing a po lysaccharide with 90% of galacturonic acid. It has a pectin-like struc ture and the neutral sugar enriched regions show a structure related t o the rhamnogalacturonan II type.
