“…The current results revealed that the functioning of the PSI in S. sclarea leaves was stimulated under excess Zn exposure (Table 2). In contrast to the observed tolerance of S. sclarea to high Zn exposure, our recent study [72] revealed that 100 µM Cd exposure for eight days caused higher toxic effects in S. sclarea plants, expressed by a stronger reduction in the chlorophyll contents, as well as by an inhibition of oxygen evolution and the activities of both photosystems.…”

“…The limit of detection (LOD) was estimated based on the standard deviation of the 10 separate blank solutions (2% HNO 3 ) and the slope of the curve (b), according to the equation: LOD = 3.3S/b. The LODs estimated for the ICP-MS method were as follows: 0.01 µg g −1 (Zn), 30 µg g −1 (Ca), 0.05 µg g −1 (Cu), 40 µg g −1 (Fe), 0.8 µg g −1 (Mg) and 0.03 µg g −1 (Mn) [72].…”

In recent years, due to the development of industrial and agricultural production, heavy metal contamination has attracted increasing attention. Aromatic and medicinal plant Salvia sclarea L. (clary sage) is classified to zinc (Zn) accumulators and considered as a potential plant for the phytoremediation of heavy metal polluted soils. In this study, an adaptation of clary sage to 900 µM (excess) Zn exposure for eight days in a hydroponic culture was investigated. The tolerance mechanisms under excess Zn exposure were assessed by evaluating changes in the nutrient uptake, leaf pigment and phenolic content, photosynthetic activity and leaf structural characteristics. The uptake and the distribution of Zn, as well as some essential elements such as: Ca, Mg, Fe, Mn and Cu, were examined by inductively coupled plasma mass spectrometry. The results revealed that Salvia sclarea is a Zn-accumulator plant that tolerates significantly high toxic levels of Zn in the leaves by increasing the leaf contents of Fe, Ca and Mn ions to protect the photosynthetic function and to stimulate the photosystem I (PSI) and photosystem II (PSII) activities. The exposure of clary sage to excess Zn significantly increased the synthesis of total phenolics and anthocyanins in the leaves; these play an important role in Zn detoxification and protection against oxidative stress. The lipid peroxidation and electrolyte leakage in leaves, used as clear indicators for heavy metal damage, were slightly increased. All these data highlight that Salvia sclarea is an economically interesting plant for the phytoextraction and/or phytostabilization of Zn-contaminated soils.

“…The biological role of anthocyanin is of pivotal importance as they can act against ROS in the vacuole, being considered antioxidants and inhibitors of lipid peroxidation [ 53 , 61 ]. In general, the anthocyanin content can increase in response to various environmental stresses [ 61 ]. Furthermore, increases in the anthocyanin biosynthesis have been proposed as a photo-protective response in rice leaves against photo-oxidative damages [ 53 ].…”

Biogenic ZnO Nanoparticles Synthesized Using a Novel Plant Extract: Application to Enhance Physiological and Biochemical Traits in Maize

The need to increase crop productivity and resistance directs interest in nanotechnology. Indeed, biogenic metal oxide nanoparticles can promote beneficial effects in plants, while their synthesis avoids the environmental impacts of conventional synthetic procedures. In this context, this research aimed to synthesize biogenic zinc oxide nanoparticles (ZnO-NPs) using, for the first time, an extract of a wild and spontaneous aquatic species, Lemna minor (duckweed). The effectiveness of this biogenic synthesis was evidenced for comparison with non-biogenic ZnO-NPs (obtained without using the plant extract), which have been synthesized in this research. XRD (X-ray diffraction), FE-SEM (field emission gun electron scanning microscopy), EDX (energy dispersive x-ray spectroscopy), TEM (transmission electron microscope) and UV-vis (ultraviolet-visible spectrophotometry) showed the biogenic approach effectiveness. The duckweed extract was subjected to UHPLC-ESI/QTOF-MS (ultra high-pressure liquid chromatography quadrupole time of flight mass spectrometry) phenolic profiling. This untargeted characterization highlighted a high and chemically diverse content in the duckweed extract of compounds potentially implicated in nanoparticulation. From an application standpoint, the effect of biogenic nanoparticles was investigated on some traits of maize subjected to seed priming with a wide range of biogenic ZnO-NPs concentrations. Inductive effects on the shoot and root biomass development were ascertained concerning the applied dosage. Furthermore, the biogenic ZnO-NPs stimulated the content of chlorophylls, carotenoids, and anthocyanin. Finally, the study of malondialdehyde content (MDA) as a marker of the oxidative status further highlighted the beneficial and positive action of the biogenic ZnO-NPs on maize.

“…Apart from this, recent studies reported anti‐inflammatory, antimicrobial and analgesic, as well as antidiabetic and cytotoxic effects 2 . In addition to biological activities, S. sclarea is one of the most economically important plants for phytoextraction and phytostabilization of zinc and cadmium contaminated soils, 28,29 and because of this, there is growing interest in cultivation of this plant.…”

Salvia sclarea L. or clary sage is cultivated worldwide in temperate and sub‐tropical climates, as an ornamental and essential oil (EO) bearing plant. EO is obtained from fresh spikes in full flowering stage and is recognized as an important commercial product for food, beverage and cosmetic industries. This study investigated the EO composition of S. sclarea grown in Serbia (Southeast Europe) obtained by two different methods, steam (SD) and hydrodistillation (HD). GC‐MS analysis identified oxygenated monoterpenes as the main class of compounds for all EOs (between 81.8% and 88.2% depending on the distillation process). The most abundant oxygenated monoterpenes were linalyl acetate and linalool. In addition, in vitro antimicrobial (modified resazurin microtitre‐plate assay) and antioxidant activities (DPPH· assay) and total polyphenol content of obtained EOs were also evaluated. According to the assay used for the evaluation of the antibacterial activity, Gram‐negative bacteria were more sensitive to S. sclarea EO in comparison to Gram‐positive bacteria. EOs exhibited low antioxidant capacity, below 3% neutralized DPPH· radicals, reaching up to approximately 400 µg AAE mL‐1. This study also investigated a possibility for predicting retention indices (RIs) of compounds isolated from EOs. In total, 78 experimentally obtained RIs were applied to construct the prediction model. The quantitative structure‐chromatographic retention relationship (QSRR) model was used to anticipate the experimentally obtained RIs. Five molecular descriptors were selected by factor analysis and genetic algorithm to predict RIs. The obtained accuracy of the QSRR model reached r2 = .912, which showed that these models might be applied for predicting retention indices.
