Hemerocallis fulva L. has been used as a traditional drug in Korea for various activities, such as antidepressant, sedatives, anticancer, antihypertensive, and antioxidant agents. This study was conducted to investigate the antioxidant components (total polyphenol and total flavonoid) and various antioxidant activities (DPPH, ABTS, and SOD) of ethanol extracts from Hemerocallis fulva L. In addition, its hypnotic effect was evaluated using a pentobarbital-induced sleep testing in mice. As a result, the high antioxidant power was found in the 50% ethanol extract, which reduced the sleep latency and prolonged the sleep duration to a level similar to those after administration of diazepam. In conclusion, it can potentially be used for development of different functional foods.
