Antimicrobial and antioxidative activity of various leaf extracts of Amphoricarpos vis. (Asteraceae) taxa

| Summary: | The antimicrobial and antioxidative activities of diethyl ether, 80% methanol
and 50% acetone extracts of the leaves of three Amphoricarpos taxa
(Asteraceae; A. neumayerianus, A. autariatus ssp. autariatus and A.
autariatus ssp. bertisceus) from the Balkan Peninsula were investigated. The
antimicrobial activity was determined by the broth microdilution assay
against eight bacterial and eight fungal species. The in vitro antioxidative
activity was assessed by the DPPH assay. The total phenolic and flavonoid
contents were also determined. The most sensitive bacterial species were
Bacillus cereus and Staphylococcus aureus. The best antibacterial potential
was obtained for the methanol extract of A. neumayerianus, while the diethyl
ether extract of this species showed the lowest effect. In general, the
tested extracts showed higher activity than the commercial antibiotics
streptomycin and ampicillin. Also, all micromycetes were sensitive to the
tested extracts. The most sensitive was Trichoderma viride. The highest and
lowest antifungal effect was determined in A. a. ssp. autariatus for the
diethyl ether and acetone extracts, respectively. The highest total phenolic
and flavonoid contents were determined in the methanol extract of A. a.
autariatus. The best antioxidative activity was demonstrated by the methanol
extract of A. a. ssp. autariatus as comparing to matching extracts from the
other two taxa. |
