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.
