“…In presented research, prescreening analysis of red and green lettuce plants under different growth conditions was done by non-invasive method based on multiwavelength induced chlorophyll fluorescence records. In previous research was found appropriate to use Multiplex measurements for flavonoids prescreening in the different type of medicinal plants (Sytar et al, 2015).…”

The aim of the study was to investigate the effect of different growth conditions on anthocyanins and flavonols accumulation in leaves of green and red loose leaf lettuce (Lactuca sativa var. crispa). Lettuce plants were grown in three types of conditions, in greenhouse (I. variant), behind clear glass in field (II. variant) and in open field conditions (III. variant). Estimation of anthocyanins and flavonols content was done by non-destructive measurements with optical fluorescence sensor Multiplex ® 3 (Force-A, France). It was estimated that green lettuce varieties had a greater flavonols content compared to red lettuce varieties in all experimental variants. The highest level of flavonols was detected in leaves of green variety Zoltán (1.218 RU) and in red lettuce had the highest amount of flavonols in variety Carmesi (1.095 RU). At the same time red lettuce varieties were characterized by higher anthocyanins content. Parameter anthocyanin index is correlated with visible red coloration of leaves. The highest content of anthocyanins was detected in variety Oakly (0.867 RU). Under the open field conditions was found statistically significant higher (P < 0.05) flavonols and anthocyanins level in both green and red lettuce leaves compared to greenhouse conditions. It may be connected with intensification of flavonoids biosynthesis and accumulation which normally stimulated by sun irradiation, especially UV-B radiation.

“…It was determined a remarkable correl between antioxidant capacity and content of total phenolics in previous explorations [17,18] as well. Previous studies showed that J. regia extracts scavenged DPPH radical in variable degrees; but, they did not scavenge DPMD and H2O2.…”

Objective: World's ageing population continues to grow older together with high percentage prevalence of Alzheimer's disease encourage science to find herbs or biologic compounds which can be utilized for it prophylaxis. Juglans regia L. is not simply an agricultural product, its fruits, leaves, barks, stems, pericarps, and flowers are all utilized for diversified medicinal usages. In the present investigation, we examined the anticholinesterase and antioxidant capacities of the lyophilized aqueous extracts of leaves from J. regia. Material and Method: Phenolic contents and antioxidant activity were assessed by Folin-Ciocalteu's, qualitative/quantitative DPPH and TBA methods. Anticholinesterase activity was assessed by Ellman's method. Result and Discussion: The total phenolic content was found 478.32 mg/g. The extract indicated antioxidant activity with DPPH test (IC50: 123.66 μg/mL) and TBA assay (IC50: 209.23 μg/mL). Moreover, the extract of J. regia indicated remarkable inhibition towards acetylcholinesterase (40.09%) and butyrylcholinesyterase (56.23%) enzymes. These data propose that J. regia can be utilised a potency for pharmaceutical products which get antioxidant and anticholinesterase activity.

“…It was detected a substantial correlation between antioxidant potential and total phenolics content in former searches as well (Sytar et al, 2015;Granato et al, 2018) Alzheimer, a neurodegenerative sickness caused by oxidative stress, is a cholinergic decrement in brain. In particular, a disruption in acetylcholine summation unleashed from cholinergic synapses has been characterized.…”

Alzheimer's disease (AD) has encouraged science to find plants or biologic compounds which can be utilized for prophylaxis of AD. Heliotropium genus is presented by 16 taxa in Turkey and they contain pyrrolizidine alkaloids, and certain are known to have antioxidant and anticholinesterase activities. The paper displays the anticholinesterase and antioxidant capacities of the aerial parts lyophilized aqueous extracts of H. dolosum, H. lasiocarpum and H. hirsutissimum. Phenolic contents and antioxidant activity of examples were determined by Folin-Ciocalteu's, qualitative/quantitative DPPH and TBA. Anticholinesterase activity was assessed by Ellman's method. The total phenolic content of H. lasiocarpum extract was found the highest (738.39 mg/g), however the total phenolic content of H. dolosum extract was found the lowest (122.731 mg/g). Every example indicated that antioxidant activity with DPPH test and H. lasiocarpum presented the highest activities (69.99 μg/mL). Furthermore, the H. lasiocarpum extract indicated considerable inhibition towards acetylcholinesterase (5.90%) and butyrylcholinesyterase (24.04%) enzymes. These findings suggest that these Heliotropium species can be effective for pharmaceutic products that achieve anticholinesterase and antioxidant activities.
