“…These results are supported by the estimated R 2 values obtained in the linear correlation between DK and vitamin C content (Table 3). Ali et al [40] arrived to the same conclusion, reporting that the content of vitamin C in berries and kiwis was improved substantially by applying high concentrations of K + .…”

Abstract:The potential impact of increased levels of potassium (K + ) in hydroponic solution on the production of bioactive compounds, which provide added value to products, is relevant for local economy and human health. This research pursues assessing different levels of K + on the nutrition of basil, an important aromatic crop in the arid region of La Laguna, northern México, where water scarcity demands the conversion from open-field agriculture to hydroponics. A randomized complete block design with a factorial arrangement (3 × 4) was used to determine the content of nutraceutical components, including polyphenolic compounds, flavonoids, anthocyanins, vitamin C, chlorophylls, and the antioxidant capacity of three varieties of hydroponic basil, with four doses of K + in the nutrient solution, 7, 9, 11 and 13 mmol L −1 . The analysis of variance showed significant differences (p ≤ 0.001) in most of the response variables, caused by the genotype and doses of K + . The antioxidant capacity of assessed cultivars was improved when doses of K + were increased in the nutrient solution. Furthermore, the antioxidant capacity was positively correlated to the content of flavonoids (r = 0.621), anthocyanins (r = 0.655) and total phenolic compounds (r = 0.549). In conclusion, the nutraceutical content was increased in basil when controlling K + in the nutrient solution.

“…Leaf infusions are also used externally for skin lesions and ulcers, and as a rinse in infections of the oral cavity and throat. This use of leaves of Rubus species relies on their high content of hydrolyzing (gallo-and ellagitannins) and condensed (catechins) tannins, and numerous other polyphenols including flavonoids (quercetin and kaempferol derivatives), anthocyanins and phenolic acids, particularly gallic and ellagic acid (Thiem, 2003;Benvenuti et al, 2004;Gudej and Tomczyk, 2004;Patel et al, 2004;Byamukama et al, 2005;Mertz et al, 2007;Ali et al, 2012).…”

We used DPPH scavenging assays to study the antioxidant activity of three native Polish species of blackberry leaves (Rubus kuleszae Ziel., R. fabrimontanus (Sprib.) Sprib. and R. capitulatus Utsch.). All the studied extracts (methanolic, water, methanolic-water) showed high DPPH free radical scavenging activity (IC50 450.0-186.0 μg/ml). The most effective of the studied species was Rubus kuleszae. Total content of phenolic compounds (70.50-136.04 mg GAE/g) and phenolic acids (14.70-38.26 mg CAE/g) was determined spectrophotometrically. Antioxidant activity correlated positively with total content of phenolic compounds and phenolic acids.K Ke ey y w wo or rd ds s: : Rubus, blackberry, leaf extract, antioxidant activity, DPPH, phenolic compounds, phenolic acids.ACTA BIOLOGICA CRACOVIENSIA Series Botanica 54/2: 32-38, 2012 DOI: 10.2478 PL ISSN 0001-5296 © Polish Academy of Sciences and Jagiellonian University, Cracow 2012 INTRODUCTIONThe genus Rubus L. (blackberries/raspberries) comprises almost 700 species, making it the largest genus of the Rosaceae family and one of the most diverse of the plant kingdom (Alice and Campbell, 1999;Zieliński, 2004). Some species such as R. idaeus and R. fruticosus are valuable fruit plants and also used in medicine. The leaves of Rubus plants are known to contain astringent, antibacterial and antifungal agents, recommended internally in diarrhoea and inflammation of the gastrointestinal tract. Leaf infusions are also used externally for skin lesions and ulcers, and as a rinse in infections of the oral cavity and throat. This use of leaves of Rubus species relies on their high content of hydrolyzing (gallo-and ellagitannins) and condensed (catechins) tannins, and numerous other polyphenols including flavonoids (quercetin and kaempferol derivatives), anthocyanins and phenolic acids, particularly gallic and ellagic acid (Thiem, 2003;Benvenuti et al., 2004;Gudej and Tomczyk, 2004;Patel et al., 2004;Byamukama et al., 2005;Mertz et al., 2007;Ali et al., 2012). Among many possible effects on biological processes in the human body, the antioxidant properties of phenolic compounds are the most important. Many data gathered in recent years indicate the participation of free radical processes in the emergence of such lifestyle diseases as atherosclerosis, heart attack, stroke, cancer, diabetes, senile cataracts and accelerated aging. The presence and distribution of numerous hydroxyl groups in the chemical structure of polyphenols make them excellent antioxidants. They are able to chelate transition metal ions, particularly those of iron and copper, which are involved in initiating free radical chain reactions. They also inhibit the activity of many enzymes participating in the formation of free radicals: for example, xanthine oxidase, responsible for the production of large amounts of reactive oxygen forms during reperfusion, and NADPH oxidase, responsible for the so-called respiratory burst (RiceEvans et al., 1996;Pietta, 2000, Villańo et al., 2007Li et al., 2008).Phytochemical studies of...

Noni has been introduced in Brazil just over a decade ago. Therefore, the information regarding crop fertilization and its influence on fruit quality is rare in the literature. Among macronutrients, potassium is highly concentrated in noni plants, and fertilization with cattle manure contributes to plant nutrition and fruit quality. This study sought to evaluate the effect of potassium fertilizer and cattle manure on the physical and physicochemical attributes of noni fruits. The treatments were distributed in randomized blocks, with four replications and two plants per plot, arranged in a factorial design 5 × 2 related to 0, 13.2, 37.5, 61.5 and 69.6 g plant -1 potassium chloride doses in soils without and with 12 kg plant -1 of cattle manure, with a C/N = 18:1 ratio. Cattle manure increased the average fruit weight from 99.6 to 113.4 g, expressing an increase of 13.9% for plants without and with organic compounds. Potassium chloride provided an increase of 61% in fruit weight and 31.25% in titratable acidity in fruits of plants without and with the highest dose of potassium chloride. Potassium chloride and cattle manure increased fruit mass, fruit length, fruit diameter, pulp mass, vitamin C and glucose contents in noni fruits.
