Abstract

B. dracunculifolia is popularly used to treat skin diseases. This work aimed to evaluate the topical anti-inflammatory properties of B. dracunculifolia root extract (BdR) and its major compound baccharis oxide (BOx) on mice ear edema models. BdR was analyzed by GC-MS, and BOx was isolated by chromatographic fractionation. Topical anti-inflammatory activities were determined by using the croton oil, capsaicin, histamine, and phenol-induced mouse ear edema models. N-acetyl-β-D- glucosaminidase (NAG) and myeloperoxidase (MPO) activities, as well as NO dosage and histopathological analyses, were also evaluated. Phytochemical analysis of BdR showed BOx as one of the major constituents. BdR and BOx (both at 0.1, 0.5, and 1.0 mg/ear) significantly reduced croton oil, histamine, and phenol-induced ear edema, while only BOx was effective in reducing capsaicin-induced edema. MPO and NAG activities, as well as NO production, were significantly inhibited by BdR and BOx. Histopathological analysis confirmed the topical anti-inflammatory properties of BdR and BOx. Our findings showed that BdR and BOx demonstrated significant topical anti-inflammatory effects in mouse ear edema induced by different agents, suggesting their possible application on skin inflammatory diseases.
