“…The catechins are present abundantly in green tea (C. sinensis), black tea, cocoa, berries, and grapes (Frei & Higdon 2003;Krzyzanowska et al 2010). Current studies informed that green tea catechins, the main components of green tea leaf, have many physiological and biochemical functions, including antioxidant (radical and oxidant scavenging, metal chelating, and inhibition of pro-oxidant enzymes), antimicrobial, anticarcinogenic, hypoallergic and blood glucose reduction in studies on different animal species (Frei & Higdon 2003;Koo & Cho 2004;Zhong et al 2009;Ariana et al 2011;Kara & Guclu 2012).…”

The aim of this study was to investigate the effect of green tea (Camellia sinensis) catechin addition to breeder quail (Coturnix coturnix japonica) diet on productivity, reproductive performance, egg quality and yolk malondialdehyde (MDA) levels during storage, and some serum biochemical parameters. In this study, a total number of 180 quail, 7 weeks of age were randomly divided into 3 groups (1 control group and 2 treatment groups) with 5 replicates (9 females + 3 males). The control group was fed basal diet; the treatment groups were fed basal diet with 0.2% and 0.4% catechin supplementation for 5 weeks. The results of this study showed that 0.2% and 0.4% catechin addition had no significant effects on live weight, feed intake, egg production, feed efficiency, and egg internal quality (yolk colour, albumen index, yolk index, Haugh units, and pH) (P > .05). Catechin addition reduced egg weight, egg specific gravity, and egg shell thickness (P < .001). The catechin addition to diet significantly diminished MDA concentrations of eggs (P < .05). Serum glucose and triglyceride levels significantly decreased (P < .05) in the 0.4% catechin group, but were not significantly affected (P > .05) in the 0.2% catechin group compared to the control group. The addition of 0.2% catechin significantly increased fertility (P < .05), hatchability (P < .01), and the hatchability of fertile eggs (P < .05). In conclusion, catechin supplementation to breeder quail diet has the potential to increase egg shelf-life and reproductive performance. On the other hand, supplementation with these catechin levels decreased egg weight and egg shell quality. ARTICLE HISTORY

“…Adequate levels of chlorogenic acid account for the resistance of potato tubers against Streptomyces scabies, Verticillium alboatrum and Phytophthora infestans, while at low concentrations it stimulates the growth of P. infestans and Fusarium solani var. coeruleum [Krzyzanowska et al, 2010]. Small concentrations of benzaldehyde totally inhibited spore germination of Botrytis cinerea and germination of Monilia fructicola.…”

“…Plant secondary metabolites are categorized in three main groups based on their biosynthetic pathways: phenolic compounds, terpenes and nitrogen-containing compounds [Rea et al, 2010;Krzyzanowska et al, 2010]. Studies have demonstrated that terpenes are synthesized via the mevalonic pathway from precursor acetyl-CoA, while phenolic compounds are aromatic substances formed via the shikimic acid pathway or the mevalonic pathway.…”

“…Phenolic compounds are secondary metabolites that encompass several classes of structurally diverse products biogenetically arising from the shikimate-phenylpropanoids--fl avonoids pathways [Krzyzanowska et al, 2010]. Plants need phenolic compounds for growth, reproduction, pigmentation, resistance to pathogens, resistance to infl uences of heavy metal-salts or in a general form to biotic and abiotic stresses [Ferrari, 2010].…”

Phenolics can be broadly divided into non-soluble compounds such as condensed tannins, lignins, and cell-wall bound hydroxycinammic acids, and soluble phenolics such as phenolic acids, fl avonoids and quinones [Krzyzanowska et al, 2010].…”

The study of secondary metabolism in plants is an important source for the discovery of bioactive compounds with a wide range of applications. Today these bioactive compounds derived from plants are important drugs such as antibiotics, and agrochemicals substitutes, they also have been economically important as fl avors and fragrances, dyes and pigments, and food preservatives. Many of the drugs sold today are synthetic modifi cations of naturally obtained substances. There is no rigid scheme for classifying secondary metabolites, but they can be divided into different groups based on their chemical components, function and biosynthesis: terpenoids and steroids, fatty acid-derived substances and polyketides, alkaloids, phenolic compounds, non-ribosomal polypeptides and enzyme cofactors. The increasing commercial importance of these chemical compounds has resulted in a great interest in secondary metabolism, particularly the possibility of altering the production of bioactive plant metabolites by means of tissue culture technology and metabolomics. In today's world the use of bioactive compounds derived from plants plays an important role in pharmaceutical applications. This review presents information about these metabolites and their applications as well as their importance in agronomy and bioactive effects on human health as nutraceuticals. This review includes also the new tendencies to produce these bioactive compounds under different stresses conditions such as biotic and abiotic stress that could be included in production systems.
