Identification of polysaccharides in Fraction I of the AQ extract, PS extract, AQ extract and ALC extract of ginseng by size exclusion chromatography. 100 μL of 5 mg/mL sample or 2.4 mg/mL standard was injected and eluted with 0.05 M NaNO3 mobile phase, this was monitored with right angle light scattering detector at 1 mL/min flow rate. Pullulan polysaccharide was used as a reference standard. The y-axis is the detector response (mV) while the x-axis represents the retention volume (mL). No signal was detected with the ALC extract, suggesting the absence of polysaccharides in this extract.
