Topical antiinflammatory activity and chemical composition of the epicuticular wax from the leaves of Eugenia beaurepaireana (Myrtaceae)

In order to verify the topical antiinflammatory effect of epicuticular wax from leaves of Eugenia beaurepaireana, it was tested in mice croton oil-induced inflammation. Our findings show that topical application of Eugenia beaurepaireana epicuticular wax was significantly active in inhibiting both o...

Our findings show that topical application of Eugenia beaurepaireana epicuticular wax was significantly active in inhibiting both oedema (Inhibitory dose 50 % (ID50) = 0.31 (0.26 - 0.39) mg.ear -1, inhibition = 79 ± 6 %) and tissue myeloperoxidase activity (indicative of polymorphonuclear leukocytes influx) (ID50 =0.34 (0.20 - 0.41) mg.ear -1, inhibition = 77 ± 4 %) in mice ear treated with croton oil.
