Abstract

Aims.Artemisia iwayomogi (AI) has been used for fever reduction, diuresis, and hepatoprotection in Korea. The present study was performed to evaluate the anti-inflammatory and antiatopic dermatitis effects of AI using bothin vitro and in vivo systems. Methods. The compositions in AI were analyzed by HPLC. To determine the anti-inflammatory effects of AI, the production of nitric oxide (NO) was measured in lipopolysaccharide treated RAW264.7 cells. Histamine levels were assayed to evaluate the antiallergic effects on MC/9 cells stimulated with phorbol-12 myristate 13-acetate and A23187. Finally, AI (10 mg/mouse/day) was topically applied onto the backs and ears of Dermatophagoides farinae-sensitized Nc/Nga mice for four weeks. Results. Isochlorogenic acid A (20.63~0.26mg/g), chlorogenic acid (9.04 ~0.08mg/g), and scopoletin (8.23 ~ 0.01mg/g)

Mogrosides IV and V were purchased from Chengdu Biopurify Photochemicals Co. (Chengdu, China)
