“…Table 4 also shows the higher a-amylase, a-glucosidase and tyrosinase inhibitory activities of P. speciosa extract than A. anatolica extract, probably justified by the highest level of phenolics. These findings are in accordance with the observed strong relationship between enzyme inhibitory activities and phenolics in plant-derived extracts [42][43][44] . Table 3.…”

The multicomponent pattern and biological characterization of plant material are essential for pharmaceutical field, in the food supplements quality control procedures and to all plant-based products. These nutrients often show valuable effects related to their consumption due to the occurrence of secondary metabolites that show useful properties on health. In this framework, researches performed on this topic play a central role for human health and drug development process. The aim of this study was to compare phenolics and free anthraquinones multicomponent pattern of two wild Turkish species: Asphodeline anatolica and Potentilla speciosa using validated high-performance liquid chromatography-photogiode array (HPLC-PDA) assays, coupled to biological evaluation. Even if some variances related to biological and enzymatic inhibition activities can be ascribed to other phytochemicals, the reported data support traditional use of Asphodeline anatolica and Potentilla speciosa roots as valuable natural font for the development of novel natural-derived drug formulations and/or food supplements with health and nutritional benefits.

Plant-based foods have become attractive for scientists and food producers. Beneficial effects related to their consumption as dietary supplements are due to the presence of natural occurring secondary metabolites. In this context, studies on these products are important for natural and safely food ingredients evaluation. The aim of this study was to evaluate root extract of eight Asphodeline species as antioxidants, enzyme inhibitors and phytochemical content. Spectrophotometric antioxidant and enzyme inhibitory assays were performed. Total phenolic and flavonoids contents as well as the chemical free-anthraquinones profiles were determined using routinely procedure (HPLC-PDA). Data show that Asphodeline roots can be considered as a new source of natural compounds and can be used as a valuable dietary supplement. Some differences related to biological activities can be inferred to other phytochemicals that can be considered in the future for their synergic or competitive activities.

Abstract:A novel industrial-scale ultraviolet-C (UV-C) light processor from AseptoRay (MGT, Israel) was used to treat a raw cold-pressed green juice blend (GJB) consisting of kale, romaine, celery, apple, and lemon. The effect of UV-C light energies of 0.88 kJ L −1 and 2.93 kJ L −1 on microbial, enzymatic, nutritional, quality, and sensory parameters of the GJB was studied. Using 2.93 kJ L −1 , 3.7 log reduction in aciduric bacteria and 3.9 logs in aerobic colony count were achieved, while lactic acid bacteria, coliforms, yeasts, and moulds were reduced by >3, >2, 2.1, and 2.1 logs, respectively. A minor increase in polyphenoloxidase (PPO) enzyme activity was seen with 0.88 kJ L −1 and a slight change in colour (not visually observed) was detected using 2.93 kJ L −1 . No other significant change in nutritional and quality parameters or enzyme activities was detected. Further, the stability of the GJB was explored. Kale and romaine contributed the most significant source of spoilage enzyme activity, cloud loss, and browning in the GJB. These stability parameters were shown to be affected by pressing temperature and pH. The commercial UV-C treatment process explored in this study is a viable alternative to high pressure processing (HPP) for improved microbial safety of fresh green juice blends.
