Raspberries composed of various varieties, are popular ingredients of daily diet with highly distinguished biological activities. In this study, a comparative investigation was conducted on various chemical potential of methanol extracts from Rubus loganobaccus L. leaf parts cultured in greenhouse and open-field. Biochemical activity of the extracts obtained from the field cultured leaves were observed to be higher than greenhouse cultured plants. In the antioxidant 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, the field cultured leaves were better succeeded in radical scavenging with IC50 as low as 1.08 ± 0.75 μg/mL while in reducing power assay, open-field plants against greenhouse plants had a higher EC50 (2.82 ± 0.70 and 2.41 ± 0.75 μg/mL, respectively). Considerable antibacterial and antifungal activity were observed in open-field plants and greenhouse plants in minimum inhibitory concentrations (MIC) and minimum bacterial concentration (MBC) tests with a similar pattern, in which the lowest MIC and MBC in open-field and greenhouse plants were 5 mg/mL and 20 mg/mL, respectively, against Bacillus cereus and pseudomonas aeruginosa. This experiment revealed that leaf parts of Rubus loganobaccus cultured in greenhouse and in field possess a number of biological properties including antioxidative and antimicrobial potentials with the superiority of the later source which indicates the criticality of using natural products to improve human health.

The objective of this study was to investigate the role of β-aminobutyric acid(BABA) (0, 300µM) in reduction of oxidative damages in leaves and roots of Brassica napus L. under drought stress (0, -0.2, -0.4 MPa). β-aminobutyric acid was investigated as an internal regulator hormone and its role in defense mechanisms against biotic and abioticstresses. In this study, BABA pretreatment prevented drought induced decrease in K+ content and increase in lipid peroxidation and H2O2 content. Mild and severe drought stress increased leaf and root MDA and other aldehydes content. In BABA pretreated plants under stress, leaf and root MDA and other aldehydes content significantly decreased as compare to drought condition.In addition, in drought stressed plants non-enzymatic antioxidants [GSH] were elevated over the control and BABA pretreatment increased GSH content. The Na+ and K+ concentration increased under mild and severe drought stress. On the basis of the results, BABA-treated plants exhibited enhanced drought tolerance. Manuscript profile
