“…Only one cauliflower genotype out of 2 and one organic cultivation out of 3 exhibited a higher polyphenols content with respect to conventional management [88]. Flavonoids and polyphenols broccoli content was unaffected by production practices [89], and no differences were found between biodynamic and conventional farming systems in the case of chicory [90].…”

relevance of scientific studies on this subject. Taking into account the reviews published since 2008, a general overlook on the research topics can emphasize the main current fields in which the research is presently developed. The different subjects which may be inferred are: problems in the analytical assays of polyphenols [1][2][3][4][5], polyphenols composition of fruits and vegetables [6][7][8][9][10], the fate of polyphenols in postharvest technology [11, 12], chemistry and biochemistry [13][14][15][16], polyphenols and food [17][18][19][20][21], polyphenols and health [22][23][24][25][26][27][28]. From this short survey which takes into account only partly the last years, the great number and variety of researches on these plants metabolites can be pointed out. There is a lack of reviews on the relations between polyphenols content, fertilization and agriculture practice, with the exception of a recent review on the possibility of differentiating organic practice by means of secondary plant metabolites in carrots [29], and the review of Stefanelli et al. [18] focused on horticulture quality under minimal nitrogen and water supply.The aim of this review is concerned with the relationships between polyphenols content, fertilization and agricultural practice correlated to soil management. Effect of nitrogen and/or potassium fertilizationAs summed up by Nguyen and Niemeyer [30], the carbon/nitrogen balance (CNB) pathways can be taken into account when studying the effect of nitrogen fertilization on phenolic content. Phenylalanine is the rate-limiting precursor for phenylpropanoid synthesis (e.g., lignin, flavonoids and condensed tannins), and at the same time, it is an essential amino acid for protein synthesis. Plant growth is heavily dependent on protein synthesis for the manufacture of photosynthetic, biosynthetic and regulatory enzymes, as well as for structural protein, and phenolic synthesis Abstract The review deals with polyphenol content of vegetables and fruits under different experimental conditions. The effect of fertilizers, mainly nitrogen containing fertilizers, on qualitative and especially quantitative content of the polyphenols mixture, was reviewed. Soil nitrogen affects both anthocyanins and flavonoids content, and generally, a higher polyphenolic content is observed when less nitrogen fertilizer is added to the soil. Also the effect of different agricultural management (conventional, organic, biodynamic, integrate) is reviewed with respect to polyphenols. In this case, a major effect has pointed out in the case of vegetables, while agricultural practice affects in a minimal way fruits polyphenols content. The effect of different management is, however, hardly pointed out, since many environmental factors are involved and affect polyphenols biosynthetic pathway.

“…The yeast extract of corn meal gave better anticancer activity than basal medium this is due to Phenolic compounds, which are important secondary metabolites; possess various biological activities, the most important of which is antioxidant activity associated with reduced cancer risk (Manach et al, 2005;Picchi et al, 2012).…”

The use of Synthetic antioxidants is being widely restricted because of their reported toxic and carcinogenic effects. Thus, now there is considerable interest being focused towards finding antioxidants from natural sources with any unlikely effects. There is also considerable evidence which indicates lower risk of Cancer in yeast extracts and the used commercial media. The present study was conducted to determine antioxidant activity of yeast extracts grown on four different commercial media using DPPH, total phenolic content, total antioxidant activity and TBARS and to study the anticancer activity of yeast extracts on the mentioned media against human hepato carcinoma cell line (HEPG-2) using the MTT assay, Cell Cycle Analysis and mRNA Expression of Cell Apoptosis-related Gene. The yeast extract of corn meal was found to have more antioxidant activity than other commercial media. The antioxidant potential was then correlated with the total phenol content. The yeast extract of corn meal showed maximum anticancer activity against HEPG-2 as compared to that of other used media. Overall, the results achieved in this study are promising and indicate that yeast fermentation on corn meal medium is better than other used media to get on antioxidant and anticancer activities.

The concentration of antioxidant compounds, the antioxidant activity, physical quality characteristics, and the yield of serrano chilies (Capsicum annuum L.) are affected by agricultural practices, such as the use of vermicompost in containers combined with chemical fertilizers, the investigations of which have focused on yield. A study was performed to determine whether vermicompost mixed with volcanic rock and the ionic composition of the nutrient solution affect the variables mentioned above. Serrano chilies were planted in volcanic rock:vermicompost in the following proportions 100:0, 80:20 and 60:40 and were watered with Steiner nutrient solution at 25, 50, and 75%. Interaction of the factors was determined for the fresh weight of the fruits. Fruit length, diameter, number, weight, yield, firmness, hue, and chroma increased with the nutrient solutions at 50 and 75%. Ascorbic acid levels fell with the solutions at 50 and 75%, and total phenols and antioxidant activity increased with the solutions at 25 and 50%. The 80:20 and 60:40 volcanic rock:vermicompost substrates similarly increased the length, diameter, number, weight, total phenols and antioxidant activity of the fruit. Yield increased with a greater proportion of the vermicompost. The solution at 50% and the volcanic rock:vermicompost mixture 80:20 were the best conditions for the content of phenolic compounds, antioxidant activity, as well as diverse quality variables, although the 60:40 proportion was more favorable for yield.
