Trifolirhizin (Standard) is a reference standard for research and analysis in studies involving Trifolirhizin. Trifolirhizin exerts varying degrees of inhibition on tyrosinase-dependent melanin biosynthesis, and therefore, are candidates as skin-whitening agents.Trifolirhizin possesses potential anti-inflammatory and anti-cancer activities.Trifolirhizin shows in vitro inhibitory effects on the growth of human A2780 ovarian and H23 lung cancer cells. Trifolirhizin inhibits acetylcholine mediated airway smooth muscle (ASM) contraction or directly relaxes pre-contracted ASM independent of β 2 -adrenoceptors.
