TL;DR: In this article, the extractionability of pressurized hot water, aqueous two-phase (20% ammonium sulfate and ethanol) and the natural deep eutectic solvent (choline chloride and citric acid) was demonstrated on dried Moringa oleifera leaves.
••
TL;DR: The results suggest that flavonoids from P. hookeri exhibit significant antibacterial activity and antiproliferative effect on human cancer cell lines, which might underlie the health benefits associated with the plant.
••
TL;DR: In this article, the effect of exogenously applied NO on maize leaf superoxide accumulation and SOD enzymatic activity in the presence and absence of salinity stress was evaluated to delineate SOD isoforms that contribute to NO-mediated salinity tolerance.
••
TL;DR: This study revealed the co-presence of phenolic acids, flavan-3-ols and xanthones in RO extracts, revealing H. perforatum roots could be considered as an alternative source to obtain antidepressant, neuroprotective and antidiabetic active substances.
••
TL;DR: In this paper, the effects of salicylic acid pretreatments on lipid peroxidation, photosynthetic pigments, the antioxidative system and cadmium (Cd) accumulation in waterlily under Cd stress were studied.

TL;DR: In this paper, the effects of exogenous application of Spermine (Spm) or Spermidine (Spd) on some physiological and biochemical processes to understand the possible mechanisms concerning the water stress alleviation in Damask rose.
••
TL;DR: The study revealed that M. barteri had the broadest spectrum of activity, with activity against C. neoformans, P. aeruginosa, vancomycin resistant Enterococci faecalis (VRE) and T. brucei, which suggests that the evaluated plants are potential sources of novel anti-infective agents.
••
TL;DR: In this article, Nitrogen was applied to the soil at rate of 0, 100, 200, 300, 400 and 400 milligrams of nitrogen per kg−1 to increase the dry biomass of roots and shoots of A. lentiformis plants.
••
TL;DR: In this paper, a spray of Si and EBL alone or in combination significantly increased the growth and photosynthetic traits in the presence/absence of NaCl stress in Brassica juncea.
••
TL;DR: It is suggested that compatible solutes increased in relation to cold tolerance mechanisms which modulate chilling-induced oxidative damage in banana.
••
TL;DR: The current findings indicated that both drug-sensitive and -resistant bacterial strains could potentially be managed using efficacious medicinal plant extracts, used either in mono- or combination therapies.
