Fig. 3From: Anti-inflammatory and antioxidative effects of six pentacyclic triterpenes isolated from the Mexican copal resin of Bursera copalliferaEffect of the isolated triterpenes on NO∙production in LPS-stimulated RAW 264.7 cells. (a) 3-epilupeol formiate, (b) α-amyrin acetate, (c) 3-epilupeol acetate, (d) lupenone, (e) 3-epilupeol, and (f) α-amyrin. The nitrite values are the mean ± SD from three independent experiments. Significance was determined by one-way ANOVA (*\( P \) < 0.01; ** \( P \) < 0.001compared to LPS)Back to article page
