Abstract
The anti-inflammatory capacity of supercritical CO2extracts (S1 and S2) obtained from sage (Salvia offi-cinalis) was evaluated using THP-1 human macrophages activated with human ox-LDL, a specific in vitromodel to determine the anti-inflammatory effect of the extracts in an atherosclerotic environment. Theexpression of pro-inflammatory cytokines, with an important role in the atherogenic process, such asTNF- , IL-1 and IL-6, in presence of different extracts concentrations was evaluated. Results showedthat 30 g/mL of both supercritical extracts (S1 and S2) markedly suppressed the ox-LDL induced pro-duction of TNF- , IL-1 and IL-6, as well as their mRNA expression. Data showed that S1 presented ahigher anti-inflammatory activity than S2.A characterization by GC–MS of sage extracts identified 16 compounds, mainly camphor, borneol and1,8-cineole. These three compounds represented a 62.4% of S1 and a 48.1% of S2. Camphor, borneol and1,8-cineole presented an important anti-inflammatory activity in the proposed model, with a decreasein the release and gene expression of TNF- , IL-1 and IL-6 and an increase in IL-10 expression. Theseresults explained the higher activity found in S1.This study suggested that supercritical sage extracts could be used as food ingredients in the develop-ment of anti-inflammatory/anti-atherogenic products.
