Abstract

Phytochemical studies were performed to identify the active principles of Phryma leptostachya var. asiatica (Phyrymaceae) for anti-inflammation. The anti-inflammatory activity was assessed by measuring the inhibition rate on nitric oxide (NO) formation in lipopolysaccharide (LPS)-activated macrophage 264.7 cells. Of the five compounds including ursolic acid, phrymarolin I, harpagide, haedoxancoside A, and acteoside isolated from this plant, ursolic acid showed the most prominent inhibition of NO formation. Therefore, ursolic acid may be the anti-inflammatory principle of Phryma leptostachya var. asiatica.

  Fig. 2 Effect of compound 1 on NO formation in LPS-activated macrophage 264.7 cells. Cells were pretreated with different concentrations of ursolic acid and stimulated with LPS (1 µg/mL). The amount of nitrate was measured by Griess reaction. The cell viability was measured using MTT. The data are presented as the means ± SD. *P < 0.05, **P < 0.01, ***P < 0.005 by t-test.
