Antimicrobial activity of some plants of Bignoniaceae family

The leaf and stem bark extracts from some species of Bignoniaceae (Adenochalyma alliaceum, Crescentia cujute, Millingtonia hortensis, Pyrostegia venusta and Tabebuia argentia), were found to show antibacterial activities towards the Gram-positive bacteria (Bacillus subtilis and Staphyloccus aureus), Gram negative (Escherichia coli) and yeast (Candida albicans).
