“…In the present study, ethanol and ethanol-water fractions were found to be the most effective in producing scavenging activity against DPPH radicals, and for garden-violet cultivar the highest values were obtained. Several studies showed also that cultivated plants possessed a higher free-radical scavenging activity against DPPH radicals than wild growing plant [17][18][19].…”

This study evaluated the effect of four different solvent, i.e., water, ethanol, water-ethanol mixture and ethyl acetate, on the antioxidant activities of wild and cultivated heather (Calluna vulgaris (L.) Hull) plant. The highest values for total flavonoid content were obtained for samples extracted using ethanol-water mixture and ethyl acetate. Cupric reducing antioxidant capacity (CUPRAC) method, scavenging ability on 1,1-diphenyl-2-pirylhydrazyl radicals (DPPH) radicals and chelating activity on Fe 2+ ions have been used for evaluation of antioxidant activity of the extracts. Ethanolic fraction exhibited the lowest reducing capacity, despite a heather sample used. The extracts of cultivated heather exhibited significant scavenging effect on DPPH radicals, and ethanol and ethanol-water fractions were found to be the most effective. The metal-chelating effect of the extracts increased in the order: ethanol < ethyl acetate < ethanol-water < water. The results may be helpful for better utilization of heather flowers extracts as potential pharmaceutical and nutraceutical ingredient.

“…However, the IC 50 of the callus extract in the ABTS test was 1236 ± 7.122 µg/mL, which was 6.84 times higher than that of ascorbic acid (181 ± 0.491 µg/mL) ( Figure 2b). The observed differences in the capacity of the callus extract to scavenge ABTS and DPPH radicals may have been mainly because, in these assays, the transfer of hydrogen and the transfer of electrons occur at different redox potentials and are dependent on the structures of the antioxidants [48]. The callus extract also showed dose-dependent ferric reducing power in the FRAP assay, which was based on the ability to reduce Fe 3+ to Fe 2+ .…”

In the present study, an aqueous extract was prepared using calli from the in vitro-derived leaves of Pyrus pyrifolia cultured in Murashige and Skoog medium containing picloram for a plant growth regulator. The major biological components in the callus extract were identified as uridine (1), adenosine (2), and guanosine (3). In terms of the antioxidant activity, at 300 µg/mL, the extract exhibited free radical scavenging activity of 76.9% ± 2.88% in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, comparable to that of 44 µg/mL ascorbic acid (82.5% ± 3.63%). In addition, the IC 50 values for inhibition of advanced glycation end product formation from collagen and elastin were 602 ± 2.72 and 3037 ± 102.5 µg/mL, respectively. The extract significantly promoted keratinocyte and fibroblast cell proliferation in a dose-dependent manner. Moreover, fibroblasts treated with 1.36 µg/mL extract exhibited a 1.60-fold increase in procollagen type I C-peptide level compared to controls. The in vitro wound recovery rates of keratinocytes and fibroblasts were also 75% and 38% greater, respectively, than those of serum-free controls at 9 and 36 h after extract treatment (1.36 µg/mL). Additionally, the extract flux across the human epidermis increased by 1598% after its incorporation into elastic nanoliposomes (NLs). Therefore, elastic NLs loaded with Pyrus pyrifolia callus extract have potential use as skin rejuvenators and antiaging ingredients in cosmetic formulations.

“…(Orobanchaceae) is a wild plant used in Mexican traditional medicine to relieve gastrointestinal diseases, and to “treat” nerves and tumors . This species synthesizes secondary metabolites such as iridoid glycosides , phenylethanoid glycosides (PhGs) , flavonoids , and lignans . These compounds have been shown to have valuable pharmacological activities such as cytotoxic , antioxidant , anti‐inflammatory , antiulcer and anti‐depressant effects .…”

The effect of exogenous spermine (SPM) on Castilleja tenuiflora shoots developing under nitrogen deficiency (ND) stress was evaluated. Shoots cultivated in a temporary immersion system were subjected to four experimental treatments: (1) control; (2) exogenous SPM; (3) ND; and (4) ND+SPM. Shoots were longer in the ND+SPM treatment (6.3 ± 0.5 cm) than in the ND treatment (4.2 ± 0.5 cm). The total chlorophyll content was similar in the control and SPM treatments (0.41 µg mg−1 FM) and the highest values of total phenolic content were detected at 21 days in the ND+SPM treatment (84.1 ± 0.05 GAE g−1 DM). In the ND+SPM treatment, the phenylalanine ammonia lyase activity increased earlier than in ND treatment, and reached its maximum at day 21 (3.9 ± 0.2 µmol E‐CIN h−1 mg−1 protein). Compared with the control, the ND and ND+SPM treatments resulted in increased secondary metabolites contents in both root and aerial parts. The strongest effect was in the roots, where the SPM and ND+SPM treatments both resulted in increased quercetin content (4.3‐fold that in the control). Our results showed that SPM partially counteract the damage caused by ND and results in increased contents of valuable bioactive compounds.
