Abstract

The mucilage of Ramonda myconi leaves is composed of several Polysaccharides differing in acidity due to the content of galacturonic acid. RMP-2 and RMP-4 are the most important fractions, where RMP-2 is an arabinogalactan containing galacturonic acid and rhamnose, probably connected to a protein moiety. RMP-4 is the major fraction, containing a Polysaccharide with 90% of galacturonic acid. It has a pectin-like structure and the neutral sugar enriched regions show a structure related to the rhamnogalacturonan II type.
