In the present investigation, evaluation of sugars viz. fructose, galactose, glucose, sucrose, lactose, maltose, and raffinose in commonly consumed raw Korean vegetables, fruits, cereals, seed plants, and leaves has been analyzed using high-performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD). Of the 58 samples analyzed, Onion showed the highest content of fructose (27.74 g/100 g) and glucose (31.80 g/100 g) and Chestnuts showed the highest content of sucrose (21.82 g/100 g). On the other hand, Glutinous sorghum (polished grain), Green tea leaves, and Paddy rice (well-polished rice) showed the lowest content of fructose (0.20 g/100 g), glucose (0.68 g/100 g) and sucrose (0.23 g/100 g), respectively. Glutinous barley (Hopimbori-whole grain) and Green tea leaves showed 0.17 g/100 g and 0.57 g/100 g of galactose and lactose respectively. Glutinous barley (Seodunchalbori-polished grain) and Black soybeans (Cheongjaho, dried) showed the highest content of maltose (0.51 g/100 g) and raffinose (1.82 g/100 g), respectively. In few samples, galactose, maltose, lactose, and raffinose were detected in trace quantities. A partial least squares discriminant analysis (PLS-DA) was also performed to discriminate the analyzed samples.
