Abstract
Antimicrobial activity of several (aqueous, ethanolic, ethereal) extracts of Calluna vulgaris aerial parts were studied in vitro, in camparison with some of its pure compounds (arbutin, hydroquinone, ursolic acid), against clinically-isolated bacteria and yeasts. Only aqueous extract was active in that inhibited the growth of some microorganisms (S. aureus, S. epidermidis, C. albicans, C. neoformans). Among pure compounds ursolic acid markedly inhibited the growth of S. aureus
