Abstract

|
The leaves of Allium victorialis (AV) are known an edible perennial herb, which has been used in Korean traditional medicine. However, the beneficial pharmacological effects of AV extracts (AVE) on the antioxidant activity and atopic dermatitis (AD) have not been thoroughly examined. Therefore, the present study aims to investigate both antioxidant activity and anti-inflammatory effect of AVE on AD in vitro and in vivo. Antioxidant activity was evaluated by total polyphenol content and ferric reducing ability. AVE showed a level of polyphenol content and reducing power activity. The five-week-old BALB/c mice were used as an AD-like mouse model by treating them with 1-chloro-2, 4-dinitrobenzene (DNCB). Topical administration of AVE for 3 weeks to DNCB-treated mice significantly alleviated clinical skin lesion dermatitis severity and epidermal thickness. Histopathological analysis also demonstrated that AVE decreased eosinophil and mast cell infiltration into skin and ear tissue. These results suggest that topical application of AVE inhibits the development of AD-like skin lesion in mice by their antioxidant activity. Thus, AVE may be a potential therapeutic agent for AD.
