“…Nevertheless, the Lachman et al 2013). A significant effect of genotype on CA and total polyphenol contents between cultivars and genotypes with yellow and white flesh was also proved recently (Navarre et al 2011). Evaluation of the effect of flesh colour on CA content (Table 3) revealed the highest CA content in average of two years and locations in the group of cultivars with purple flesh (518 mg/kg FM); significantly lower CA content achieved cultivars with red flesh (342 mg/kg FM), and the lowest content was observed in the group of cultivars with yellow and white flesh (77.1 mg/kg FM).…”

In precise field trials in the years 2010 and 2011 the effect of genotype and location in cultivars with yellow, white, purple or red flesh on the content of chlorogenic acid (CA) and in 2011 and 2012 the effect of organic cultivation were evaluated. The results show a statistically significant effect of genotype to CA content, which ranged from 74.0 mg/kg fresh matter (FM) (Agria) to 825 mg/kg FM (Vitelotte). Demonstrable effect of flesh colour on CA content between cultivars with coloured flesh was found (430 mg/kg FM) in comparison with cultivars with yellow or white flesh (71.1 mg/kg FM). For cultivars with coloured flesh rather the genotype specific cultivar ruled than the purple or red flesh colour. In terms of the influence of location, higher CA levels were found on warm locations with frequent periods of drought in comparison with locations of high altitude climatic conditions which are favourable for potato cultivation. In the organically grown potatoes significantly higher levels of CA were found as compared with conventional treatment.

“…In average of all thirteen varieties higher antioxidant activity at the Přerov nad Table 4) has been demonstrated. This result is certainly related to higher TAC at Přerov nad Labem sit, as these compounds are in addition to ascorbic, chlorogenic and caffeic acid major antioxidants of potatoes (Lachman et al 2009, Ezekiel et al 2011, Navarre et al 2011. Dependence of AOA on TAC.…”

“…Potatoes are significant source of natural antioxidants and exhibit antioxidant activity as demonstrated in recent time by many authors (Karadeniz et al 2005, Reyes et al 2005, Nara et al 2006, Navarre et al 2011, Zarzecka and Gugala 2011. Studies have indicated that these phytochemicals have high free-radical scavenging activity, which helps to reduce the risk of chronic diseases and age-related neuronal degeneration (Teow et al 2007).…”

The aim of this study was to determine that the total anthocyanin content (TAC) and antioxidant activity (AOA) in potato flesh with different colours grown in the Czech Republic. Four yellow-or white-, six purple-and four red-fleshed varieties were grown in 2009 at two different sites (Valečov -highland, seed potato area at 460 m a.s.l., Přerov nad Labem -lowland, new potatoes area at 178 m a.s.l.) in precise field trials. For purple-and red-fleshed varieties, average TAC values ranged from 61.5 to 573.5 cyanidin mg/kg of FM and significant effect of the variety of the TAC was found. High content reached the Violette and Vitelotte varieties with dark purple flesh, and the lowest content the Blue Congo variety with light purple marbled flesh. Significantly higher TAC was found in a lowland area Přerov nad Labem, which is probably related to drought stress. The lowest AOA was achieved by a group of varieties with yellow or white flesh -averaging 82.8 mg ascorbic acid equivalent/kg FM, in a group of red-fleshed varieties it was higher 4.34 times and in a group of purple-fleshed varieties even 5.03 times higher. Also between purple-and red-fleshed varieties significant differences in AOA were found, both high and low values of AOA showed the same varieties as in the case of the TAC. Among experimental sites higher AOA was also demonstrated at Přerov nad Labem. Correlation analysis showed a strong correlation between AOA and TAC (r = 0.8099).

“…Results of the three-factor analysis of variance show that tyrosine content mostly depends on the individual properties of potato cultivar (coeffi cient η 2 variety=0.65) of all investigated factors. Other researchers exploring the free tyrosine content in potato tubers also confi rmed its dependence on cultivar (ANDRE et al, 2009;NAVARRE et al, 2011;AYVAZ et al, 2015). The recorded amounts of tyrosine in potato tubers range from 24 μg g -1 to 231 μg g -1 .…”

It was determined that amounts of chlorogenic acid, tyrosine, and tryptophan in potato tubers depend on meteorological conditions, farming type, individual properties of a variety, and interaction of these factors (P<0.05). It was noted in 2011 that organically grown potato tubers accumulated signifi cantly higher amounts of chlorogenic acid, tyrosine, and tryptophan derivatives than conventionally grown tubers, while in 2012 the opposite was observed (P<0.01). Such results are due to the different meteorological conditions during the survey years.
