Quantitative composition of monosaccharides present in the polysaccharides obtained from P. boydii by hot alkaline extraction as evaluated by gas chromatography

Monosaccharides were analyzed by detection of their alditol-acetate derivatives using a capillary column DB-225 (25 × 0.22 mm) programmed for a temperature of 170–210 °C with a variation of 20 °C/min.

	Percentual of monosaccharides
	Unfractionated polysaccharides	Fraction II
Rhamnose	7.9	26.5
Mannose	16.5	38.5
Glucose	72.4	28.2
Galactose	3.2	7.7
