“…Coloured varieties of crops have a higher antioxidant potential thanks to anthocyanins. The antioxidant activity of these crops is mainly expressed in higher levels of antioxidants determined by ABTS and DPPH methods (Flores et al 2015). Kirakosyan et al (2015) observed a higher content of anthocyanins in rat livers experimenting with tart cherry.…”

The influence of anthocyanins on antioxidant activity and liver function was measured in three different animal species (rats, chickens and fish). Purple Konini wheat with the total anthocyanin content (TAC) of 41.70 mg/kg was fed to the experimental groups of animals (rats n = 32; chickens n = 32; fish n = 20). The same numbers of animals (control groups) were fed common wheat with TAC of 24.95 mg/kg. At the end of the experiment, the animals were killed and blood and liver tissues were taken for biochemical analyses. The liver enzyme activities were measured in blood. Antioxidant activity in the liver tissue was measured using the DPPH (2,2-diphenyl-1-picrylhydrazyl test), FR (Free Radicals method), FRAP (Ferric Reducing Antioxidant Power method), and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) test. Significantly higher values (P < 0.05) measured by the DPPH and FR methods were determined in the liver from rats fed Konini wheat. The chickens fed Konini wheat showed significantly different values using DPPH, FR and ABTS methods. No significant differences were found in hepatopancreases of fish. Animals fed Konini wheat showed a tendency to lower liver enzyme activities in general, but a significant difference was found only in gamma-glutamyl transferase activity in the chicken's blood. Our results suggest that feeding a higher content of anthocyanins can improve the antioxidant activity and function of the liver tissue. Rats, chickens, fish, free radicals, radical scavenging activityBesides the contents of nutrients and toxic substances in rations, researchers lately increasingly focus on the biologically active substances with protective and preventive effects against the degenerative diseases and other health problems that may lead to the shortening of life (Ficco et al. 2014;Kaur et al. 2014). In recent years, much attention has been paid to researching a number of substances with antioxidant action, which include vitamins, microelements, and many other compounds naturally occurring in plants and producing positive effects both in human and animal nutrition (Abdel-Aal and Hucl 2003;Englmaierová et al. 2011;Suchý et al. 2014;Sun et al. 2014). Health benefits have been partly attributed to the unique phytochemicals present in the whole grain (Liu 2007). Flavonoids possess antioxidant properties against reactive oxygen species.Antiallergic, anti-inflammatory, and analgesic effects were also demonstrated, including the ability to affect nutrient transfer at the capillary level (Opletal and Skřivanová 2010). In crop species, the edible organs show large variations in colour. In the wheat grain, which is a staple food for humans and grain feed for animals, the colour is mainly due to natural classes of pigment: carotenoids and anthocyanins. Anthocyanins accumulate in the aleurone or pericarp of wheat and provide the blue, purple and red colours of the grain (Ficco et al. 2014). Anthocyanins could be the major compounds distinguishing purple wheat from other coloured wheats for their high...

“…Some authors have proposed guava fruits are potentially nutraceutical due to their high contents of vitamins, minerals, and polyphenolic antioxidants (Hassimotto et al, 2005;Ho et al, 2012). Other parts of the guava plant have been used to treat diabetes, caries, wounds, diarrhea, inflammation, and hypertension (Gutiérrez et al, 2008), and have been reported as having anti-plasmodial, anti-inflammatory, hepatoprotective, anticancer, and antioxidant activities (Salib and Michael, 2004;Ojewole, 2006;Roy et al, 2006;Flores et al, 2015). The wide variety of applications and ecological importance of the species there is constant progress of numerous research efforts for improving its agronomical characteristics.…”

Molecular markers have proven to be powerful tools in research related with diversity, variability, and improvement of economically important tropical crops. This study analyzed eight physiological and morphological fruit characters of economic interest in the cultivated Mexican guava (Psidium guajava L.), and assessed the suitability of two sequence specific amplified polymorphism (SSAP) and simple sequence repeat (SSR) markers developed for their use in early selection of individual plants with given fruit characteristics. Principal component analysis (PCA) explained 79% of the morphological variability observed among accessions. S-SAP was more informative than AFLP for studies of variability and diversity in guava, the former marker showing higher percentage of polymorphism (90%) and more intraspecific variability (0.58). It was analyzed by cluster analysis using the unweighted pair group with arithmetic means (UPGMA) method the relationships between accessions from nine guava varieties. S-SAP dendrograms clustered varieties in better agreement with pulp color and fruit shape, suggesting a possible association of the S-SAP marker with quantitative trait loci (QTL) related to fruit physiological and morphological fruit characters. According to results, the microsatellites mPgCIR131, mPgCIR136 and mPgCIR161 might also be linked to QTL related to internal and external pulp thickness, pulp color, and soluble solids, indicating that the SSR markers developed are appropriate for their use in early selection of guava individuals having specific fruit features, therefore being suitable for molecular marker assisted selection (MAS) of the crop.
