An aqueous-methanolic [methanol:water (1:1)] extract of the whole plant of Artemisia pallens (Family: Asteraceae) has shown good antibacterial activity against Pseudomonas aeruginosa and Shigella flexneri at the concentration of 100 mg/mL. The activity-guided fractionation has led to isolation of compound 4-hydroxyphenyl-?-D-glucopyranoside (which is known as arbutin), as a major constituent and exhibited the same antibacterial activity at a concentration of 17 mg/mL. Both the crude extract and arbutin also showed 94% anticorrosive efficiency against mild steel in 1M HCl at concentration of 200 mg/L.

Keywords: Artemisia pallens; antibacterial activity; anticorrosive efficiency and arbutin.
