Abstract
This study reports the first phenolics from Wissadula genus (Malvaceae) and the anti-inflammatory activity of 7,4′-di-O-methylisoscutellarein. Using chromatographic methods, five phenolic compounds were isolated from aerial parts of Wissadula periplocifolia (L.) C. Presl. The compounds were identified as 4-hydroxybenzoic acid, 3-hydroxybenzoic acid, trans-cinnamic acid, tamgermanetin and 7,4′-di-O-methylisoscutellarein using spectroscopic methods. The flavone 7,4′-di-O-methylisoscutellarein showed anti-inflammatory activity by inhibiting neutrophils recruitment in a mice model of pleurisy and by decreasing significantly the production of cytokines IL-1β and TNF-α.
