Abstract
The aim of this study was to explore the effect of capsaicin and particular phenolic compounds profile from cellulase assisted extracts of Habanero (Capsicum chinense) chili pepper seeds (CPS) on the concentration of cytokines (IL-2, IL-6, TNF-α, IL-1β) in murine macrophages (RAW 264.7) stimulated with lipopolysaccharides (LPS). Capsaicin was quantified by HPLC-DAD, and the phenolic profile was determined by UPLC-MS-QqQ. Anti-inflammatory activity was evaluated by Mouse Cytokine/Chemokine Magnetic Bead Panel 96-well plate assay. Among the 15 different phenolics found in CPS extracts obtained at 120 or 150min of maceration with 2,500 UI/L at 30ºC or 45 ºC in a 1:15 (w:v) proportion, the most abundant was vanillic acid (7.97-12.66µg/g). The extract obtained at 30ºC and 120min, showed similar effects than the observed for synthetic anti-inflammatory drugs indomethacin and dexamethasone, and capsaicin standard. Beyond capsaicin, salicylic, protocatechuic and trans-cinnamic acids as well as vanillin in CPS extracts were correlated with the anti-inflammatory effect. On the other hand, capsaicin and chlorogenic acid contents were potential immunostimulants whose concentration varied depending on the cellulase treatment time.
