“…Thus, presumably, the better antibacterial properties of green-synthesized ZnONPs, as compared to plant extracts, are due to their stability. Several researchers have reported on the function of V. album leaf extracts as antibacterial agents [46,47]. The ZnONPs are known to interfere with bacterial DNA replication and drastically change how virulence-causing genes are expressed in the bacteria, which limits the pathogenic potential of the bacteria [48].…”

The current study explored the antioxidant and antibacterial capabilities of zinc oxide nanoparticles (ZnONPs) synthetized using methanolic leaf extracts of the medicinal herb Viscum album. Through TEM investigation and UV–Vis analysis, which peaked at 406 nm, the synthesis of ZnONPs was verified. TEM analyses showed that the synthesized ZnONPs had a size distribution with an average of 13.5 nm and a quasi-spherical shape. Forty-four phytoconstituents were found in the methanolic leaf extracts of V. album. Additionally, a comparison of the antibacterial effectiveness and antioxidant capacity of aqueous and methanolic extracts of wild-grown V. album phytomedicine and green-manufactured ZnONPs was conducted. The green-generated ZnONPs were examined against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa and shown to have superior antibacterial activity by 22%, 66%, and 44%, respectively, as compared to wild herbal medicinal extracts. Since the ZnONPs’ aqueous extracts had higher concentrations of DNA gyrase-B inhibitory components, they were shown to be more effective in limiting bacterial growth. In contrast to the percentages of 49% and 57% for a wild plant extract, the aqueous- and methanolic-extract-mediated green ZnONPs, with a 100 g/mL concentration, showed 94% and 98% scavenging capacity for DPPH free radicals, respectively. However, methanolic extracts were more effective than aqueous extracts in terms of the antioxidant analyses. This study establishes that greenly produced ZnONPs have the potential to be used in nanomedicine to treat bacteria that are resistant to a variety of drugs, as well as those with reactive oxygen species toxicity.

Doğada bulunan birçok bitki, fenolik bileşik yönünden zengin olup doğal antioksidan ve antimikrobiyal özellikler taşımaktadır. Bu nedenle, bitkiler biyoteknolojik alanda önem kazanmaya ve kronik hastalıkların tedavisi için alternatif kaynak olarak tercih edilmeye başlanmıştır. Günümüzde önemli bir sağlık sorunu olan diyabet hastalığının tedavisinde anti-diyabetik özellik taşıyan bitkilerin kullanılabileceği düşünülmektedir. Bu özelliğinden dolayı bitkiler, son yıllarda araştırmacıların odak konusu haline gelmiştir. Bu bitkilerden birisi olan ve birçok hastalığın tedavisinde kullanılan ökse otunun (Viscum album), diyabet hastalığının tedavisi için de etkili olabileceği düşünülmüştür. Bu sebeple, bu çalışmada Artvin Arhavi bölgesinden toplanan armut ağacı üzerinde yetişen ökse otu bitkisinin üç farklı çözgen (kloroform, aseton, etanol) ile hazırlanmış ekstrelerinin fenolik ve flavonoid madde, antioksidan kapasite, antimikrobiyal aktivite ve enzim inhibisyon aktivite tayinleri yapılmıştır. Çalışmadan elde edilen sonuçlar göz önüne alındığında günümüzde yüksek bir biyolojik aktiviteye sahip olan ökse otu bitkisinin ilaç endüstrisinde kullanım potansiyelinin olduğu söylenebilir.

In the present study, plants species growing in different habitats (gypsum, limestone, serpentine) within the province of Erzincan Gypsum (Gypsophila lepidioides, Psephellus recepii, Tanacetum heterotomum, Verbascum alyssifolium), limestone (Chrysophthalmum montanum, Cyclotrichium niveum, Phlomis oppositiflora, Teucrium leucophyllum) serpentine (Convolvulus pseudoscammania, Fumana aciphylla, Gladiolus halophilus, Hypericum thymbrifolium, Salvia indica) were examined. The phenolic (TPC) and flavonoid (TPF) content and the amount of antioxidant activity (DPPH, FRAP) were analyzed in different organs of the plants, including leaves, branches and roots. The results were evaluated by means of SPSS Statistical Program and differences were observed between habitats. A strong correlation was found between the phenolic and flavonoid contents of plants and their antioxidant activities. The findings showed that the phenolic, flavonoid content and antioxidant activities of plants grown in different ecological conditions vary significantly.
