  • Publication number: 20230020109
    Abstract: A pharmaceutical composition and a health functional food composition for alleviating eye fatigue containing, as active ingredients, compounds, particularly, luteolin-7-O-diglucuronide and apigenin-7-O-diglucuronide isolated from a Perilla frutescens (L.) Britton var. acuta (Thunb.) Kudo leaf extract have an effect of alleviating eye fatigue by increasing the contents of NO and cGMP associated with relaxation of ciliary smooth muscle cells isolated from rat's eyes and decreasing the content of [Ca2+]i, and increasing cGMP which is a factor associated with relaxation of the ciliary smooth muscle through an animal experiment. As a result, the luteolin-7-O-diglucuronide and apigenin-7-O-diglucuronide compounds extracted from Perilla frutescens (L.) Britton var. acuta (Thunb.) Kudo may be usefully used as a pharmaceutical composition and a health functional food composition having an eye fatigue alleviating effect as a Korean natural resource.
