To investigate physiochemical characteristics of Liriope platyphylla tubers by various drying process, proximate constitute, levels of free sugar, organic acid, free amino acid, crude saponin and spicatoside A were analyzed. Drying methods included hot-air drying (DLR, 60℃, 48 hr) and roasting after hot-air drying (RDLR, roasting at 180℃ for 15 min). The moisture, crude protein, crude lipid, ash and NFE (nitrogen free extract) contents of FLR (fresh Liriope platyphylla tuber) were 69.99%, 1.85%, 0.02%, 0.79%, and 27.35%, respectively. The most abundant proximate component of DLR and RDLR was NFE, of which the contents in both sample were 80.09% and 86.07%, respectively. The major free sugars in DLR and RDLR was oligosaccharide Ⅱ as 56~57% and the major organic acid was malic acid as 3.06~3.34%, respectively. In free amino acid, the major amino acid of FLR, DLR and RDLR was serine with contents of 477.41 mg%, 1394.88 mg%, and 180.33 mg%, respectively. The level of serine was significantly decreased by roasting process. The level of crude saponin in FLR, DLR and RDLR were 3.52%, 8.41%, and 10.15%, respectively.
