Abstract

Dried aerial parts (leaf, stem, and flower) of Calycotum villosa (Poiret) Link were collected from Edough mountain (Annaba, North of Algeria), during the flowering period in March 2010. Crude extracts of the aerial parts were prepared using solvents of various polarity (CH2Cl2 and MeOH). Preliminary phytochemical and antibacterial properties of the extracts were investigated. The results showed the presence of some chemical families including alkaloids, flavonoids, sterols and triterpenes. It was found that the CH2Cl2 crude extract revealed a strong activity against Acinetobacter sp. and Klebsiella pneumoniae drug-resistant bacteria stains. This study supports the potential use of Calycotum villosa extracts to kill bacteria causing some infectious diseases such as pneumonia.
