Isolation and Identification of 2-O-Methyl- l -rhamnose and 3-O-Methyl- l -rhamnose as Constituents of an Acidic Polysaccharide ofChlorella vulgaris

The monosaccharides 2-O-methyl-l-rhamnose and 3-O-methvl-l-rhamnose were isolated and identified as components of the acidic polysaccharide of Chlorella vulgaris K-22. 2-O-Methyl-l-rhamnose was first found in algae.
