Abstract
Chrysanthemum indicum Linne, belonging to the family Compositae, is a perennial herb that is widespread in Korea. C. indicum Linne flowers have been traditionally used as an oriental medicine for treatment of infectious diseases. The chemical compositions, antioxidant capacity, and neuroprotective effects of volatile components in essential oils from C. indicum Linne flowers were investigated. GC-MS analysis of essential oils revealed the 15 major components of 1,8-cineole, o-cymene, camphor, pinocarvone, chrysanthenyl acetate, bornyl acetate, trans-caryophyllene, terpinen-4-ol, umbellulone, trans-pinocarveol, cis-verbenol, borneol, α-terpineol, caryophyllene oxide, and thymol. Thymol had the highest antioxidant capacity. Essential oils and thymol dose-dependently decreased intracellular oxidative stress, exhibited anticholinesterase activities, and increased the cell viability of neuronal PC-12 cells. Essential oils and thymol from C. indicum Linne flowers can be sources of natural antioxidants and functional foods.
