Abstract:The antifungal activity of five solanaceae glycoalkaloids solanine, chaconine, solasonine, solamargine and tomatine against phytopathogenic fungi Cercosporella brassicae and Alternaria porri has been evaluated. Tomatine showed the highest antifungal activity against C. brassicae and A. porri among five compounds, followed with chaconie, solamargine and solasonine, while solanine showed the lowest antifungal activity. Mixture of potato glycoalkaloids solanine and chaconine produced marked synergistic antifungal activity. The magnitude of synergisms is higher at lower concentrations than that at higher concentrations. The antifungal activity of individual glycoalkaloid against A.porri was relative low, even no activity, but the mixture of chaconine and solanine show significant synergism. There was no synergism between glycoalkaloids solasonine and solamargine from Solanum nigrum in inhibiting fungul growth. The mixtures of solamargine and chaconine, and solasonine and solanine both caused additive inhibition on the growth of fungi. | |||
