Antioxidant and Antiradical Activity of Beetroot (Beta vulgarisL. var.conditivaAlef.) Grown Using Different Fertilizers

Abstract

Fertilizers in different nitrogen forms (calcium ammonium nitrate (CAN), urea, ammonium sulfate (AS), and ammonium nitrate (AN)) and their doses (50, 100, and 150) for beetroot (BT) (Beta vulgaris L. var. conditiva Alef.) and the antioxidant and antiradical activities in the lyophilized water and alcohol extracts of BT were evaluated. In order to evaluate antioxidant and radical removing activities of BT roots, total phenolic compound amount assignment, total flavonoids amount assignment, method of Fe 3+ -Fe 2+ reduction activity using ferric cyanate reduction, cupric ions (Cu 2+ ) reducing capacity with CUPRAC method, Fe 3+ reducing capacity according to FRAP method, ferrous ions (Fe 2+ ) chelating activity, superoxide anion radical (O 2 •− ) removing activity, and 2,2 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS •+ ) radical removing activity were determined. In the study, BHA and -tocopherol were used as standard antioxidants. It was determined that water and alcohol extracts obtained from BT roots indicated reduction activities, effectively. In addition, it was also determined that these reduction activities were indicated in most BT roots grown in fertilizer media at lower percentage and that they had higher antioxidative level than that of standard antioxidants.

Antimycotoxigenic Activity of Beetroot Extracts against Alternaria alternata Mycotoxins on Potato Crop

“…Our results showed that the TPC of BME (2.52 mg GAE/g) was approximately 2-fold of the TPC of BEE (1.34 mg GAE/g). Our findings were in accordance with previous studies [15,31,32], which reported that the methanol extract had higher concentration than the beetroot ethanol extract. The TPC of Beta vulgaris roots was 20-fold of the TPC of the other parts.…”

Metabolomic Analysis and Antioxidant Potential of Tropical Propolis Nonpolar Extracts from Colombia

“…It is also possible to note that propolis with higher concentrations of carotenoids, polyphenols, terpenoids, and some nonoxygenated terpenes such as α-zingiberene presented greater antiradical capacity due to the fact that the Z2 and the Z4 samples are located in the same place than the antioxidant variables. This effect has been reported in other studies where the objective was to study the antioxidant effect of ginger [58,59], beet [60,61] and other plants such as parsley, garlic, myrtle, and fennel [62]. Such plant species and the propolis samples herein studied are rich sources of both polyphenols and terpenic metabolites, e.g., zingiberene, ar-curcumene, linalool, pinene, p-cymene, and limonene.…”

Studies regarding the production of a novel yogurt using some local plant raw materials

“…Red beetroot is rich in valuable active compounds such as carotenoids, betalains, polyphenols, and flavonoids, and saponins incorporation of novel natural flavorings and components in fermented dairy products could ensure manufacture of products with health‐enhancing nutraceuticals and functional properties (Bazaria & Kumar, ). It is very rich as regards B vitamins (B1, B2, B3, and B6) and folic acid great interest due to its beneficial effects on human health, including stimulation of the immune and hematopoietic systems, and anti‐inflammatory, antitumor, hepatoprotective, antiradical, and antioxidant properties, may be useful for improving blood sugar level and hypertension (Babagil, Tasgin, Nadaroglu, & Kaymak, ; Sawicki, Baczek, & Wiczkowski, ). They also inhibit cervical ovarian and bladder cancer cells in vitro, cardiovascular disease (Ravichandran et al, ).…”
