Hydroxycinnamic acids in cooked potato tubers from Solanum tuberosum group Phureja

Abstract

Hydroxycinnamic acids are phenolic compounds and are considered to have health promotion properties due to their antioxidant activity. Potato tubers of 113 genotypes of Solanum tuberosum group Phureja belonging to the Colombian Central Collection, landraces of potatoes, and commercial cultivars were evaluated for their hydroxycinnamic acids content. The composition of these compounds was analyzed using cooked tubers in two different agro-climatic conditions. The genotypes were analyzed for chlorogenic acid, neo-chlorogenic acid, cryptochlorogenic acid, and caffeic acid by ultrahigh-performance liquid chromatography (UHPLC). Chlorogenic acid was the major representative and varied between 0.77 to 7.98 g kg −1 DW (dry weight) followed by crypto-chlorogenic acid (from 0.09 to 1.50 g kg −1 DW). Under moorland agro-climatic conditions even though the chlorogenic acid levels increased with respect to flatland agroclimatic conditions, the related isomer neo-chlorogenic acid decreased as compared to flatland conditions. The correlation between chlorogenic acid with the isomers, and with caffeic acid was positive. This study demonstrated that there is a wide variation in hydroxycinnamic acids contents in the germplasm studied, which can be exploited in breeding programs to contribute to human health.

Chromosomes I and X Harbor Consistent Genetic Factors Associated with the Anthocyanin Variation in Potato

“…Recent evidence suggests that the Solanum tuberosum Group Phureja, a cultivated potato group, which is mainly comprised of diploid genotypes, contains higher nutritional value than other potato species [8][9][10]. These potatoes possess a wide variability in important nutritional traits, flesh and skin colors from yellow to purple [8,[11][12][13], and contain health-promoting compounds such as polyphenols, including anthocyanins, and carotenoids [14][15][16][17]. In recent years, there has been an increasing interest in potatoes with red and purple flesh or skin, and they have attracted the attention of researchers, as well as consumers, due to their antioxidant properties, taste, and appearance [18][19][20][21].…”

Breeding Differently: Participatory Selection and Scaling Up Innovations in Colombia

“…Therefore, potatoes can play a significant role in addressing food insecurity and nutritional problems, which are the major causes of the global health challenge. The potato, in addition to being a source of energy and fibre, has important nutritional traits (Clayton and Percival 2000; Andre et al 2007a;Nassar et al 2012;Ezekiel et al 2013;Peña et al 2015) and contains health-promoting compounds such as polyphenols and chlorogenic acid (Andre et al 2009;Kubow et al 2014;Liyao et al 2016;Piñeros-Niño et al 2016). Because of its high consumption and its nutritional attributes, and because it is the economic axis of thousands of small-scale producers, the potato is a crop that can effectively link agriculture and nutrition and achieve an impact in the rural sector.…”

Proximal composition, bioactive compounds and biorefinery approach in potato tubers of Solanum tuberosum Group Phureja: a review

“…The water is by far, the most abundant component in potato tubers, with moisture content values ranging in a slightly lower interval in Group Phureja (72.1–80.8 g/100 g Fresh Weight, FW) as compared to those in Group Tuberosum (73.1–88.8 g/100 g FW). As presented before, potato tubers of Group Phureja are considered a good source of energy because of their high percentage of digestible carbohydrates (Bonilla & Pérez, ; Piñeros‐Niño et al , ; ICBF, ). Starch, the main representative of the digestible carbohydrates, is present in a slightly higher range in the potato tubers of Group Phureja (8.7–22.7 g/100 g FW) than in Group Tuberosum (9.1–19.5 g/100 g FW).…”

“…This last one is of special importance in the Andean countries, including Colombia and Peru (Ghislain et al , ). On the one hand, Colombia reports research on 108 genotypes from the Colombian Core Collection, 13 native landraces, four commercial genotypes and seven advanced breeding clones of the Group Phureja (Peña et al , ; Duarte‐Delgado et al , ; Piñeros‐Niño et al , ; Narváez‐Cuenca et al , ). On the other hand, Peru has a collection of 170 genotypes of this group, including some genotypes that are commercialised, with part the collection being characterised on their nutritional and bioactive compounds contents (Andre, Ghislain, et al , ; Andre et al , ; Burgos et al , , ).…”
