Abstract
This study was conducted to evaluate the inhibitory effects of Yongseollan(YSL) on the production of nitric oxide (NO) and the expression of inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-activated RAW264.7 cells. YSL is tropical plant originating from Mexico. The biological activity of this plant is not yet evaluated systematically. The aim of the present work is to investigate a potential anti-inflammatory activity of YSL. The RAW264.7 cells were cultured in D MEM/F12 medium for 24 hrs. After serum starvation, cells were treated with YSL for 1 hr, followed by stimulating NO production with a LPS. We found that YSL has an inhibitory effect on the production of NO, iNOS expression and
