Kurzfassung:
This study describes the antimicrobial and anti-inflammatory effects from extracts obtained from the leaves of Salvia lavanduloides. The plant material was macerated with three solvents of ascending polarity (n-hexane (Sl-Hex), ethyl acetate (Sl-AcOEt), and dichloromethane (Sl-D)). The extracts, fractions (SlD-2 and SlD-3), and isolated compounds (15,16-epoxy-10-β-hydroxy-neo-cleroda-3,7,13(16),14-tetraene-17,12R:18,19-diolide (1), salviandulin A (2), and eupatorin (3)) were evaluated as antimicrobials against Gram-negative, Gram-positive bacteria and the fungus Candida albicans (Ca) using the minimum inhibitory concentration (MIC) and the anti-inflammatory activity induced by 13-acetate of 12-O-tetradecanoylforbol (TPA). Sl-D and Sl-AcOEt extracts, SlD-2 and SlD-3 fractions showed the highest antimicrobial activity. The isolated compounds showed good activity against Pseudomonas aeruginosa with a MIC 〈 2 μg/mL, while the anti-inflammatory activity, the Sl-Hex, Sl-D extracts, and SlD-3 fraction presented an inhibition of 62, 45 and 61%, respectively, while (2) 70% and (3) 72%.
