The antimicrobial activity of 18 different extracts from
in vivo and
in vitro grown
L. album L. plants was evaluated against clinical bacteria and yeasts using the well diffusion method. All the used extracts demonstrated antibacterial activity, whereas only the water extracts from leaves (
in vivo) possessed antifungal activity against
Candida albicans
NBIMCC 72 and
Candida glabrata
NBIMCC 8673 (14 and 20 mm diameter of inhibition zones and MIC 10 mg/ml, respectively). The methanol and ethanol extracts obtained from the
in vitro propagated plants had a broader spectrum of antibacterial activity than those from
in vivo plants, while the opposite tendency was observed for the chloroform extracts. All tested flower extracts possessed antimicrobial activity. The chloroform extract from
in vivo flowers demonstrated the highest activity against
E. faecalis
NBIMCC 3915,
S. aureus
NBIMCC 3703,
P. hauseri
NBIMCC 1339 and
P. aeruginosa
NBIMCC 3700 (22 mm, 13 mm, 11 mm, 23 mm zone diameter of inhibition and MIC 0.313 mg/ml, respectively). The water extracts from leaves (both
in vivo and
in vitro) possessed higher antibacterial activity than extract from flowers. The obtained results showed that both
in vivo and
in vitro propagated
L. album L. could be used as a source of antibacterial substances.
