“…Antimicrobial activities of Pf-AgNPs and P. frutescens leaf extract were estimated by the microdilution test against fungus strain of C. albicans (ATCC 10231) and bacteria strains including E. coli (ATCC 25922), and S. aureus (ATCC 25923) 32 . The leaf extract of P. frutescens and Pf-AgNPs were prepared (50 mg/mL) and serially diluted with Mueller-Hinton broth for bacterial (0.006-12.5 mg/mL) and fungal (0.031-32 mg/mL) cultures and thereby Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Minimum Fungicidal Concentration (MFC) of samples were evaluated as described in our recent study 33 .…”

Green synthesized‎ nanoparticles (GSNPs) display fascinating properties compared to physical and chemical synthesized ones. GSNPs‎ are currently used in numerous applications such as food packaging, surface ‎coating agents, environmental remediation, antimicrobial, and medicine. In the present ‎study, the aqueous leaf extract of Perilla frutescens L. having suitable capping, reducing, and stabilizing compounds was used for green synthesis of silver nanoparticles (Pf-AgNPs).‎‏ ‏The ‎bioreductant capacity of aqueous leaf extract of P. frutescens for Pf-AgNPs was determined by ‎different confirmatory techniques including‎ UV-Visible spectroscopy, XRD, FESEM, EDX‎, zeta potential, DLS, SERS, and FTIR‎ analysis. The results exhibited that Pf-AgNPs had optimal size (< 61nm), shape (spherical), and ‎stability (-18.1 mV). The antioxidant activity of Pf-AgNPs with both DPPH and FRAP assays ‎was significantly higher compared to P. frutescens ‎extract. Furthermore, Pf-AgNPs had high antimicrobial activity against ‎Escherichia coli and Staphylococcus aureus (MIC=‎ ‎‎0.78 mg/mL), and Candida albicans (MIC=‎ ‎‎8 ‎mg/mL)‎ while the plant ‎extract showed ‎low antimicrobial activity‎ against both bacterial strains and the fungus tested. Pf-AgNPs ‎and P. frutescens ‎extract also ‎exhibited moderate toxicity on MCF-7‎ cancer cells‎ with IC50 values ‎of ‎346.2‎ and ‎467.4 µg/mL‎, respectively. The results provide insights into using the biosynthesized Pf-AgNPs as an eco-friendly material for a wide range of biomedical applications.

“…Uras Güngör et al 12 , have been obtained the same results in the aerial parts T. velutina Boiss. According to the pervious study 47 , TPC were highly correlated with DPPH and ferric reducing antioxidant power values. However, Gupta and Prakash 48 found that the TPC and antioxidant activity (IC 50 ) of fenugreek leaf extract were 158.3 mg tannic acid equivalent/100 g and 27.69 mg/ml, respectively.…”

Fenugreek (Trigonella foenum-graecum L.) is a multi-use annual forage legume crop that is widely used in food products such as syrup, bitter run, curries, stew, and flavoring. In the present study, morphological traits, proximate composition (moisture, crude fibre, protein, fat, carbohydrate, and energy value), total phenol and total flavonoid contents, and antioxidant properties of 31 Iranian agro-ecotypic populations of the plant was investigated. Among the leaf and seed samples studied, the seeds exhibited the high ash (3.94 ± 0.12%), fat (7.94 ± 0.78%), crude fibre (10.3 ± 0.25%), protein (35.41 ± 1.86%), and carbohydrate (50.5 ± 1.90%) content. In general, more energy value (kcal/100 g) was also obtained from the seed (318.88 ± 1.78–350.44 ± 1.27) than leaf samples (45.50 ± 1.32–89.28 ± 0.85). Antioxidant activity and power of leaf samples were ranged from 67.95 ± 0.05‒157.52 ± 0.20 μg/ml and from 45.17 ± 0.01‒361.92 ± 0.78 μmol Fe+2 per g dry weigh, respectively. Positive linear correlations between antioxidant activity and total phenolic compounds were observed. A significant correlation between proximate composition (dependent variable) and some morphological features (independent variable) was observed. Considerable variability in the studied traits among the plant samples can be interestingly used in further food and production systems.

Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Minimum Fungicidal Concentration (MFC) of samples were evaluated as described in our recent study 37 . The MIC of Pf-AgNPs and plant extract were evaluated for 3 microorganisms in triplicates by double fold serial microdilution test using 96-well microliter plates according to the Clinical laboratory standard Institute (CLSI).…”
