The component sugars were separated and identified on a
3% OV-225 (1/800 · 60) column using a Shimadzu 14-B Gas Liquid chromatography equipped with flame ionization detector at 200 C column temperature, and 250 C injector and detector port temperatures. Nitrogen (40 ml/min) was used
as the carrier gas. A sugar mixture consisting of rhamnose,
arabinose, xylose, mannose, galactose and glucose was used
as reference sugars.
