Abstract

Methanol extract obtained from Kielmeyera variabilis stems showed significant molluscicidal activity against Biomphalaria glabrata. The phytochemical studies of the plants stem to the isolation of three xanthones (assiguxanthone-B, kielcorin and 1,3,5,6-tetrahtydroxy-2-prenylxanthone) and a organic acid (2,5-dihydroxy benzoic acid). The structures of these compounds were identified by IR, MS, ¹H and 13C NMR spectral analysis and comparison with literature data.
