Abstract: The present invention relates to a method for quantifying 3,6-anhydro-L-galactose using high-performance liquid chromatography and a differential refractometric index detector, whereby L-AHG and D-galactose, which are saccharification products of agarose or agar, can be independently quantified by controlling the separation conditions of the high-performance liquid chromatography/differential refractive index detector, even though the two materials are difficult to separate due to having similar molecular weights and structures.
