Apiaceae is one of the most important families containing a large variety of plants. Members of this family are well known for their analgesic, antibacterial, antiviral, and anticoagulant effects. This study described the HPLC-identification of phenolic compounds in four plants belonging to family Apiaceae, i.e. Anethum graveolens, Petroselinum crispum, Deverra tortuosa and Daucus syrticus. Catechin, chlorogenic acid, and rutin were found in all 70 % ethanolic extracts of plants, according to HPLC analysis. Except for Anethum graveolens, all plants contained apigenin. Caffeic acid was exclusively found in Deverra tortuosa. All extracts were to be devoid of gallic acid and hesperidin. Quercetin was found in Daucus syrticus and Anethum graveolens, while kampferol was found only in Daucus syrticus, and ellagic acid was found in Daucus syrticus and Petroselinum crispum. The four extracts had no effect on Aspergillus fumigates and Staphylococcus aureus, while the extract of Anethum graveolens had no effect on Proteus vulgaris. The extracts of Deverra tortuosa and Anethum graveolens demonstrated the best effects on Bacillus subtilis and Candida albicans, respectively. Petroselinum crispum produced also the best effect on Bacillus subtilis. The highest levels of antioxidant activities were observed for Deverra tortuosa and Daucus syrticus.
