“…Limonene also had a good effect on scopolamine-induced amnesia, where it improved the alterations generated by scopolamine in short-term memory that were found in several cognitive abilities scrutinising tests [109]. This effect was observed in limonene's ability to ameliorate scopolamine's impact on short-term memory.…”

Neuroinflammation is a characteristic sign of a wide variety of neurodegenerative diseases, including Alzheimer's and Parkinson's, amongst others. Microglia, which are native immune cells found in the brain, become activated very quickly in response to a brain infection or injury. When microglia become overactivated, their production of pro-inflammatory and cytotoxic chemicals can become unregulated and uncontrolled, which is the primary cause of neuroinflammation. Microglia are principally responsible for neuroinflammation. As a result, the investigation of novel approaches to reduce neuroinflammatory reactions is an essential component of neurodegenerative disease treatment. In the research of brain inflammation, bacterial lipopolysaccharide is frequently used. This compound is responsible for the initiation of a number of significant cellular processes that significantly contribute to the pathophysiology of neuroinflammation.

“…As in our previous study that adopted foliar Nr EO application [ 4 ], Arabidopsis shoots exposed to 2 Nr EO and 4 Nr EO via atmosphere displayed growth reduction and a decrease in soluble sugars content, but no significant changes in organic acids content. Applied in a similar way, this EO has previously been reported to induce growth inhibition of ragweed ( Ambrosia artemisiifolia L.) shoots [ 29 ], and garden cress seedlings ( Lepidium sativum ) [ 35 ]. Regardless of the method of application (foliar or via-atmosphere), Nr EO induced a decrease in Chl a, Chl b and Chl a+b content in Arabidopsis [ 4 ], but also in ragweed shoots [ 29 ].…”

“…These results are in accordance with previous studies, which described Nr EO-induced alterations in the antioxidative defense system of ragweed ( Ambrosia artemisifolia ) shoots, characterized by increased POX activity and decreased CAT and SOD activities [ 29 ]. Furthermore, reference [ 35 ] showed that nepetalactone-rich EOs decreased POX, CAT, and SOD (Fe-SOD and CuZn-SOD) activities in cress seedlings. The decrease in POX, CAT, and SOD activities in Arabidopsis roots was recorded for 2 Nr EO treatment, which might be the result of decreased ROS formation and further studies are necessary to confirm this hypothesis.…”

Phosphinothricin (PPT) is one of the most widely used herbicides. PTT targets glutamine synthetase (GS) activity in plants, and its phytotoxicity is ascribed to ammonium accumulation and reactive oxygen species bursts, which drives rapid lipid peroxidation of cell membranes. In agricultural fields, PPT is extensively sprayed on plant foliage; however, a portion of the herbicide reaches the soil. According to the present study, PPT absorbed via roots can be phytotoxic to Arabidopsis, inducing more adverse effects in roots than in shoots. Alterations in plant physiology caused by 10 days exposure to herbicide via roots are reflected through growth suppression, reduced chlorophyll content, perturbations in the sugar and organic acid metabolism, modifications in the activities and abundances of GS, catalase, peroxidase, and superoxide dismutase. Antagonistic interaction of Nepeta rtanjensis essential oil (NrEO) and PPT, emphasizes the existence of complex control mechanisms at the transcriptional and posttranslational level, which result in the mitigation of PPT-induced ammonium toxicity and in providing more efficient antioxidant defense of plants. Simultaneous application of the two agents in the field cannot be recommended; however, NrEO might be considered as the PPT post-treatment for reducing harmful effects of herbicide residues in the soil on non-target plants.

“…Allelopathic potential of this genus was revealed. Phytotoxicity of Nepeta essential oils has been mainly tested (Kobaisy et al, 2005, Eom et al, 2006, Mancini et al, 2009, Mutlu et al, 2011, Kekec et al, 2012, Bozari et al, 2013, Živković, 2013. Allelopathy of water extracts has been studied by Mutlu and Atici (2009) and Babaahmadi et al (2013).…”

In the present study the bioherbicidal activity of essential oils hydrodistilled from Nepeta glocephalata Rech.f and N. ispahanica Boiss were investigated on four weed species (barnyard grass (Echinochloa crus-galli (L.) Beauv), redroot pigweed (Amaranthus retroflexus L.), lambsquarters (Chenopodium album L.) and canary grass (Phalaris canariensis L.)). A total of 37 components were identified from the essential oils of N. glocephalata and N. ispahanica constituting approximately 98.61 % and 96.1 % of the oils, respectively. In laboratory bioassay different concentrations (0, 1, 2, 4 and 8 μl ml-1) of two Nepeta essential oils on germination, root and shoot length were studied. Results showed by increasing the concentration of oils, all studied traits of the weeds were decreased compared with control. In a glass house bioassay post-emergence application of Nepeta essential oils (1.25 %, 2.5 %, 5 % and 10 %, v/v) on 3-week-old weed plants caused visible injury (7-days after spray) ranging from chlorosis to necrosis of plant weeds. In foliar application under glasshouse conditions, both Nepeta essential oils reduced the seedling dry mass and concentrations of chlorophyll a chlorophyll b. The study concludes that Nepeta essential oils have phytotoxic effects and could be used as bioherbicides but the selectivity of these compounds should be considered also.
