This study was to appraise the anti-inflammatory and free radical scavenging activities of ethanol extracts of Ilex ficoidea Hemsl (EIFH) and Ilex centrochinensis S.Y. Hu (EICC). Anti-inflammatory activities were evaluated using xylene-induced ear edema and the cotton pellet granuloma tests. Some antioxidants produced during chronic inflammation were quantitated and the DPPH, superoxide anion and hydroxyl free radicals scavenging activities in vitro were also investigated. EICC showed a significant anti-inflammatory effect during the acute inflammation and chronic inflammation without any acute oral toxicity. However, EIFH exhibited a negligible anti-acute inflammatory and a moderate anti-chronic inflammatory activity. EICC significantly inhibited the formation of MDA and markedly raised the activities of SOD, CAT and GSH-Px. EIFH could reduce the level of MDA and elevate the activity of SOD only at the high dose. The free radical scavenging activities of EICC are higher than that of EIFH. These results suggest that EICC possesses significant anti-inflammatory and free radical scavenging activities. The anti-inflammatory mechanism is attributed, in part, to enhance the activities of antioxidant enzymes.
► Firstly evaluated the anti-inflammatory and free radical scavenging activity of two Ilex species. ► I. centrochinensis S.Y. Hu shows higher anti-inflammatory activities than I. ficoidea Hemsl. ► The anti-inflammatory mechanism is attributed to enhance the activities of some antioxidant enzymes. ► I. centrochinensis S.Y. Hu shows higher free radical scavenging activities than I. ficoidea Hemsl.
