evaluation of antioxidant and antibacterial activities of the bioactive compounds from the leaves of ferulago trifida boiss.

The phytochemical analysis of methanolic fraction from leaves of ferulago trifida boiss. led to the identification of rutin (1), narcissin (2), heraclenol (3), xanthotoxin (4), imperatorin (5), bergapten (6), prantschimgin (7), umbelliferone (8), isogosferol (9), isopimpinellin (10), and oxyimperatorin (11). the antibacterial effect of the isolated compounds was investigated, and umbelliferone and isogosferol showed a moderate antibacterial effect on s. epidermidis (iz: 15 mm, mic: 500 μg/ml) and s. dysenteriae (iz: 16 mm, mic: 500 μg/ml), respectively, compared to gentamicin and rifampin. the antioxidant capacity of the methanolic and chloroform extracts elucidated from leaves was examined by dpph and frap tests. the results showed weak antioxidant potency in the dpph method for methanol (ic50: 81.1 µg/ml) and chloroform fractions (ic50:125.2 µg/ml) compared to bht (ic50: 19.2 µg/ml) as a positive control. the methanol extract (67.1 ± 2.9 mmol fse/100 g) and chloroform extract (77.4 ± 4.1 mmol fse/100 g) also showed weak antioxidant activity according to the frap compared to the bht (267.2 ± 4.2 mmol fse/100 g).
