Phytochemical and anthelmintic study of the root bark of Teclea trichocarpa, Engl. (Rutaceae)

Abstract

The root bark of Teclea trichocarpa exhibited anthelmintic activity against egg hatching and larval development of sheep nematodes (Strongyloides). Three compounds, namely lupeol, melicopicine and 6-methoxytecleanthine were isolated from the dichloromethane-methanol (50:50) extract of the plant. Melicopicine and 6-methoxytecleanthine exhibited mild anthelmintic activity. The present study lends scientific credence to the traditional use of Teclea trichocarpa in the treatment of human helminth infections.
