Nanoparticles are materials that can be used in a wide range from medicine to industry. In recent years, especially the fruits, flowers, leaves, and roots of plants have come to the fore in nanoparticle synthesis because they are environmentally friendly and economical. Rosa damascena is a plant that is used both in foods such as jams, desserts, and beverages, and in many cosmetic products such as perfumes, creams, and lotions due to its pleasant smell and taste. In addition to its pleasant taste and aroma, valuable bioactive components are among the main uses of these flowers. Berberis crataegina fruit is a wild shrub fruit that can be consumed by humans but is unknown to many. This study aims to examine the antibacterial and antioxidant properties of silver nanoparticles produced from Rosa damascena flowers and Berberis crataegina fruits, both of which are rich in anthocyanins. For this, first of all, the produced silver nanoparticles were evaluated using SEM and SEM EDX. In addition, the size and properties of the nanoparticle were defined by performing XRD and FTIR analyses. In addition, antimicrobial, and antioxidant analyses analyses of these nanoparticles were performed. As a result, two different silver nanoparticles with high antioxidant properties were synthesized from both. However, nanoparticles synthesized from R. damascena flower showed more antimicrobial activity than nanoparticles synthesized from Berberis crataegina fruit.
