Adenophora remotiflora (Mosidae) is a perennial plant in the Campanulaceae family and a wild plant that only inhabits in Korea. This research analyzed the volatile compounds in Mosidae and their antioxidant activities. The volatile compounds in fresh, shady air-dried, and freeze-dried Mosidae were isolated by steam-distillation extraction (SDE) method using diethylether as a solvent. Volatile compounds were analyzed by gas chromatography-mass spectrometry (GC/MS). Antioxidant activities were determined using the linoleic acid system and 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. Sixty and seventy-two volatile compounds were identified from fresh and shady air-dried Mosidae, respectively. In fresh Mosidae, the most abundant compounds were ethyl acetate and heptyl acetate, while ethyl acetate and limonene were the most abundant in the shady air-dried sample. Inhibition of peroxide formation by fresh Mosidae was higher than that of , and inhibition by shady air-dried Mosidae was same as that of . Furthermore, volatile compounds from shady air-dried Mosidae had higher free radical scavenging activity than . The freeze-dried sample showed lower antioxidant activity in both the linoleic acid system and DPPH method.
