A Comparative Study on Phytochemical Potentials of Rubus Loganobaccus L.

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 openfield. 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, openfield 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.
