Phytochemical composition, cytotoxicity, antioxidant and antimicrobial responses of Lavandula dentata L. grown under different levels of heavy metals stress condition

Variability in Chemical Composition and Biochemical Activities ofMentha x piperitaL. Essential Oil, in Response to Mycorrhizal Symbiosis and Heavy Metal Stress

“…The possible cytotoxicity of M. x piperita essential oil was evaluated using a lethality bioassay with brine shrimp ( Artemia salina Leach), as described by Terfi et al. [96] . The brine shrimp eggs were provided by the National Center of Research and Development of Fisheries and Aquaculture (NCRDFA), Algiers, Algeria.…”

“…The possible cytotoxicity of M. x piperita essential oil was evaluated using a lethality bioassay with brine shrimp (Artemia salina Leach), as described by Terfi et al. [96] The brine shrimp eggs were provided by the National Center of Research and Development of Fisheries and Aquaculture (NCRDFA), Algiers, Algeria. About 1 g of brine shrimp eggs was placed in recipient containing 1 L of artificial seawater (36 g of sea salt/1 L of distilled water, supplied by oxygen and provided directly by light and heat (~27/28 °C) by using 60-W lamp).…”

“…The 24h-LC50 were calculated as Mercury (Hg) (mg kg À 1 ) nd 0.001-0.04 *: soil sample was air-dried and sieved to < 2 mm for physico-chemical properties, including pH (1/2.5; soil/distilled water, after 1 h stirring), electrical conductivity (1/5 soil/distilled water, after 1 h stirring), particle size distribution [92] , total nitrogen (Kjeldahl procedure), total phosphorus [93] , Organic matter (OM) by loss on ignition at 550 °C for 8 h, and total organic carbon by dividing the OM content by a factor of 1.724 [94] ; **: United States Department of Agriculture (USDA-1964); ***: C/N ratio < 12 ) fast mineralization ) more nutrients available to plant;****: The total Na, K, Ca, Mg, Zn, Cu, Fe, Al, Mn, Pb, Cr, Ni, As, Co and Cd contents were determined by flame atomic absorption spectrometry after digestion of the sample soil according to Terfi and Sadi [95] . Hg content was determined by Mercury Analyzer (Nippon Instruments Corporation/Japan) according to Terfi et al [96] . Each metal content (μg/g of dry weight) was reported as means of triplicate analyses.…”

Phytochemicals Involved in Mitigating Silent Toxicity Induced by Heavy Metals

“…The use of natural agents was The health risks associated with HMs can occur either indirectly, through the consumption of vegetables, fruits or cereals grown in contaminated soils, or directly through the inhalation of dust or the consumption of contaminated drinking water. When the con-centrations of HMs exceed a certain threshold, they induce toxic effects [20,21]. Regulatory agencies in several countries have determined the maximum allowable limits for HMs in dietary supplements and nutraceuticals to protect consumers.…”

Integrated Multiomics and Synergistic Functional Network Revealed the Mechanism in the Tolerance of Different Ecotypes ofSalvia miltiorrhizaBge. to Doxycycline Pollution

“…After evolving from water to land, early terrestrial plants evolved unique and complex environmental response mechanisms, the most representative of which is the downstream secondary metabolic pathway of aromatic amino acids (AAAs). Among the 20 natural amino acids, AAAs and their downstream metabolites have a more flexible response to complex physical and chemical factors such as drought, UV-B, salt, and heavy metals due to their conjugated benzene ring structures. Notably, the downstream branch of the phenylalanine–tyrosine metabolic pathway accounts for most of the secondary metabolic network in plants.…”
