The goal of this study was to investigate the nutritional characteristics and physiological functionality of Liriope tuber for development of new bioactive compound from Liriope tuber. Crude protein and carbohydrate contents of Chenogsim were 9.25% and 77.98%, respectively and crude protein, 9.86% and carbohydrate, 79.08% were also contained in Liriope tuber No.1. Both of Liriope tubers were showed very high contents of sucrose (Cheongsim; 4.08%, Liriope tuber No.1; 4.91%), oxalic acid (0.98%, 0.86%) and glutamic acid (3.736 g/100 g, 4,196 g/100 g). Among several physiological functionalities, tyrosinase inhibitory activity were showed very high 86.4% in Cheongsim and 82.02% in Liriope tuber No.1, respectively.

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, $60^{\circ}C$, 48 hr) and roasting after hot-air drying (RDLR, roasting at $180^{\circ}C$ 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$\sim$57% and the major organic acid was malic acid as 3.06$\sim$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.
