n this study, GC/MS of volatile oils and lipid constituents were explored for four Apiaceae family members: Deverra tortuosa (Desf.) DC., Daucus syrticus L., Anethum graveolens L. and Petroselinum crispum (Mill.). The potential of using the ethanolic extracts of these plants in the synthesis of green silver nanoparticles (AgNPs) was investigated. Additionally, the effect of these synthesized nanoparticles on some strains of bacteria and fungi was studied. About the lipoidal matter, the data show that, D. tortuosa and D. syrticus had 32 and 13 compounds, respectively, while A. graveolens and P. crispum had 24 ,19 compounds, respectively. The Analysis of volatile oils by GC/MS allowed the identification of 31 compounds in D. tortuosa and D. syrticus had 23 compounds, while A. graveolens had 18 compounds and P. crispum had 11 compounds. The data showed that, the size of AgNPs differed according to the plant used in their synthesis as follows: 34.0, 42.7, 37.3, and 41.0 nm for D. tortuosa, D. syrticus, A. graveolens and P. crispum, respectively. It was observed that, AgNPs from P. crispum had the highest effect against Bacillus subtilis (22 mm), while the best activity against Escherichia coli was 20 mm from AgNPs of D. tortuosa ethanolic extract. AgNPs of A. graveolens ethanolic extract had the best effect against Aspergillus versicolor with inhibition zone of 40 mm, followed by D. syrticus (38 mm).
