Extracts of Styrax ramirezii Greenm., a fruit traditionally valued for health and wellness in Mexico, were analyzed phytochemically and evaluated for antioxidant and anti-inflammatory activity. Six nomeolignans were identified by HPLC-TOF-MS, and the two major compounds were isolated for further evaluation. The effects of the isolated nomeolignans, egonol and homoegonol, on lipopolysaccharide (LPS)-induced nitric oxide (NO) production, reactive oxygen species (ROS) production, and biomarkers of inflammation were evaluated. Of the tested compounds, egonol potently inhibited the production of NO and also significantly reduced the release of ROS. Consistent with these observations, the mRNA expression levels of inducible nitric oxide synthase (iNOS) (0.668 +/- 0.108), cyclooxygenase-2 (COX-2) (0.553 +/- 0.007), interleulcin-1 beta (IL-1 beta) (0.093 +/- 0.005), and interleulcin-6 (IL-6) (0.298 +/- 0.076) were reduced by egonol. The activity for both egonol and homoegonol increased in a concentration-dependent manner. These results suggest the potential of S. ramirezii Greenm. fruit to contribute to a healthy diet, rich in antioxidant and anti-inflammatory compounds.
