A total of 16 ethanolic extracts from 10 different plant species were investigated. The determination of the MIC by means of the liquid dilution method (Table 1) showed that 5 plant extracts tested exhibited an antimicrobial effect against some of the five tested micro-organisms.
The results showed that the extracts from Sanguisorba officinalis, Tussilago farfara (aerial part; rhizome), Chelidonium majus (root), Tribulus terrestris (aerial part) and Schisandra chinensis (leaves) possessed antimicrobial activity.
Although the plants differ significantly in their activities against the micro-organisms tested, more of the extracts showed antimicrobial activity against B. cereus and S. aureus than against E. coli, P. aeruginosa and C. albicans.
According to the liquid dilution screening method for antimicrobial activity of higher plants reported by
