Does host plant affect the antibacterial activity of Tapinanthus bangwensis (Engl. K. Krause) Danser (Loranthaceae)

Abstract

The extracts of fresh leaves and twigs of Tapinanthus bangwensis (Engl. and K. Krause) obtained from different host plants were screened for their antibacterial activities against six human pathogenic bacteria. The methanolic extracts showed activity against Shigella dysenteriae and Salmonella typhimurium. The antibacterial activity of chloroform extracts, where activity was shown, revealed more activity than those of methanolic extracts. Antibacterial activities vary according to host plants on which T. bangwensis was obtained.   Key words: Tapinanthus bangwensis, antibacterial activity, Loranthaceae, Pathogens, Nigeria
