“…The optical properties of the samples were investigated by measuring the UV-visible spectroscopy [20]. The main peaks showed primary and secondary amides, and amines, proteins, alcohols, aromatic hydrocar-bons, aldehydes, ketones and carboxylic acids, as well as stretching and bending vibrations, proved that all these are connected with Zn-NPs [9]. The exogenous foliar application of Sorghum bicolor leaf extract-mediated Zn-GNPs increased the physicochemical attributes in okra plants.…”

“…The green approach of NPs synthesis depends upon the plant source and the organic compounds present in the plants [6]. The plants secrete some of the important phytochemicals that act as both cappings or stabilizing and reducing agents, which are provided separately in case of synthesis through chemical and physical methods [9]. The effect of the nanoparticles depend upon the concentration, pH and temperature [6].…”

The study investigated the green and chemical approaches for the preparation of Zn nanoparticles and their effect on the growth of okra plants under saline conditions. The leaf extract of Sorghum bicolor L. was used for the green synthesis of zinc nanoparticles (Zn-GNPs). Zinc nanoparticles (Zn-NPs) were also produced by the co-precipitation method (Zn-CNPs). The synthesized NPs were characterized by UV-visible spectroscopy, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) and were applied foliarly in the range of 0.1%, 0.2%, 0.3% on okra plants. A marked increase in the shoot and root fresh and dry weight (g) and chlorophyll contents were observed under normal and saline conditions. An increase in antioxidant activity was observed under saline conditions. However, the foliar application of 0.3% Zn-GNPs was helpful in the regulation of the antioxidant defense system under a saline environment. Based on the results, it can be concluded that the use of Zn-GNPs is the most promising eco-friendly approach in mitigating salinity stress.

O queijo coalho produzido com leite de vaca é um produto típico do Brasil, sendo considerado um patrimônio da região Nordeste, local de sua origem. Este agrega fonte de renda para seus produtores e comerciantes movimentando a economia de diversas cidades. Assim, este trabalho tem por finalidade avaliar a ação do extrato aquoso das folhas do coentro adicionado ao queijo coalho frente aos microrganismos Salmonella spp. e Staphylococcus aureus bem como analisar a qualidade sensorial deste produto após a adição do extrato e a sua influência em alguns parâmetros físico–químico. Pode-se observar que na avaliação sensorial o coentro promoveu pequenas alterações nos parâmetros avaliados, assim, como nos aspectos físico-químico, porém não foram significativos a nível estatístico. Na avaliação microbiológica constatou-se uma redução do teor de S. aureus para o queijo contendo o extrato. Concluísse que mais estudos são necessários para avaliar a redução microbiana na amostra contendo o extrato aquoso do coentro e que a aceitabilidade do queijo foi positiva.

The aim of the study was to examine the influence of extraction method on the size, shape and morphology of synthesized silver nanoparticles (AgNPs). Silver nanoparticles were prepared by the aqueous and methanolic extracts of lemon balm. The properties of obtained nanoparticles were characterized by UV-Vis, SEM, XRD and FTIR techniques. The UV-Vis spectroscopy confirmed the formation of AgNPs by observing a distinct surface Plasmon resonance band around 450 nm. SEM images showed different shape, size and morphology of AgNPs using two different extracts types. AgNPs derived from the aqueous extract were rod-shaped with a diameter of 19 to 40 nm whereas spherical particles were synthesized by the methanolic extract found smaller with size distribution ranging from 13 to 35 nm. The XRD pattern indicated that AgNPs formed by the reduction of Ag + ions using methanolic extract of M. officinalis were crystal-like in nature. The functional groups of M. officinalis methanolic extract involved in synthesis and stabilization of AgNPs were investigated by FTIR. In addition, AgNPs-containing methanolic extract showed higher antioxidant activity. These particles exhibited remarkable antimicrobial activity against gram positive and negative bacteria and a fungus. The nanoparticles produced by the methanolic extract of the lemon balm showed antioxidant and antimicrobial activity. The production of silver nanoparticles using plant extract is rapid, low cost and eco-friendly. Therefore, green chemistry is a good alternative to industrial production of nanoparticles. Silver nanoparticles can be used as an antiseptic to sterilize the surrounding area and the hospital wastes.
