“…The highest levels of TPC and antioxidant activity were observed in the extracts obtained at 160 °C. TPC content obtained at this temperature was 266% higher than that reported by Lee et al () for asparagus spears. The potential antioxidants by DPPH and FRAP presented maximum levels of 1,453.09 and 4,201.96 (μmol of Trolox per g of dried asparagus by‐product), respectively, which are higher than the values reported by Lee et al () (10.90 μmol of Trolox per g) and Sun, Powers, and Tang () (13.30 μmol Trolox per g) for asparagus spears.…”

The aim of this study was to submit the asparagus by‐product to the subcritical water treatment, evaluating the extraction of antioxidants compounds (AC) and total reducing sugars (TRS), as well as, the composition and technological properties of the residual material. The effects of temperature (100–160 °C) and pressure (100–200 bar) on extraction were evaluated, for total extraction time of 120 min. The results showed that the increase in temperature favored the removal of AC and this variable did not cause modification of most of the compounds identified by mass spectra analysis. The highest removal of AC was observed up to 30 min. The increase in temperature decreased the TRS content. The pressure did not affect the extraction of sugars and AC in the conditions evaluated. The treatment was efficient for the modification of the physico‐chemical composition and technological properties of residual material, reducing the TRS content and improving the ratio of soluble fiber to insoluble fiber. Practical applications Asparagus by‐product can be an interesting source of nutrients, like dietary fiber and antioxidant compounds. To maximize the antioxidant yield obtained from this by‐product, it can be used the subcritical water extraction (SWE) that is considered a green solvent. Besides this, the SWE promotes the concentration of dietary fibers of the treated material, due to the sugars removal, and improves the functional properties, which can facilitate the utilization of this material in the development of new food products.

The favourable active ingredient composition of numerous vegetables is published frequently; however its value is often influenced by the variety and the given production year. In the current experiment the main aim was to determinate the bioactive materials (total polyphenol, flavonoid, vitamin C, sulphate-S, protein, nitrate-ion) of blanched (white) asparagus for three widely known varieties ('Cumulus', 'Vitalin', 'Grolim'), grown on mouldy brown sandy soil, in 3 consecutive years (2012)(2013)(2014). A significant difference has been found among the varieties in the average of the observed data. 'Vitalin' was prominent with its high total polyphenol (35.16 mg/100 g), vitamin C (59.34 mg/100 g) and flavonoid (0.52 mg/100 g) content. High sulphate-S content -which is characteristic for asparagus -has been measured in the case of 'Cumulus' (287.77 mg/100 g), together with the highest protein content (2.23%). The vitamin C content of the spears is significantly influenced by the production year, therefore higher temperature fluctuations had a negative effect on it, which resulted in its value reducing to one-tenth of the best years in some cases (89

“…However, large differences can M. Palfi et al: TOTAL POLYPHENOL CONTENT AND ANTIOXIDANT ACTIVITY WILD AND ... be partly explained by various analysis modifications both in the extraction of polyphenols and in the results. Phenol biosynthesis in plants is dependent on a number of environmental factors, such as UV radiation, soil, biotic or abiotic stress (Cheynier et al, 2013); it is also dependent on the timing of the harvest of asparagus (Lee et al, 2014). Cultivation conditions, especially light conditions, are of great importance for the rutin and polyphenol content (Maeda et al, 2010).…”

SUMMARYAsparagus is an interesting vegetable as a part of a healthy diet and has been widely studied due to the high nutritional value and potential positive effects on human health. Wild asparagus (Asparagus acutifolius L.) grows along the Adriatic coast and islands, while the cultivated asparagus (A. officinalis L.) is mostly grown in the eastern region of Croatia. The aim of this study was to determine total polyphenol content (measured spectrophotometrically) and antioxidant activity (DPPH) in wild and cultivated asparagus. No significant differences in total polyphenol content were found between wild and cultivated asparagus. The highest content of polyphenols in wild asparagus was 6. [mg GAE/g fresh weight] and 49.60 [mg GAE/g dry weight], and in cultivated asparagus it was 4.52 [mg GAE/g fresh weight] and 50.93 [mg GAE/g dry weight]. Antioxidant activity measured using DPPH (2,2-diphenyl-1-picrylhydrazyl) method showed statistically significant difference. Higher antioxidant activity was measured in cultivated than in wild asparagus. The results also indicate that increased polyphenol content leads to higher antioxidant activity, but more so in the cultivated asparagus. Based on the results, the cultivated asparagus is an excellent alternative to wild asparagus that should be protected from over-harvesting, thus preventing devastation of plant diversity of islands and coast.
