Characterization and Quantitation of Phenolic Compounds in New Apricot (Prunus armeniaca L.) Varieties

Abstract

Thirty-seven apricot varieties, including four new releases (Rojo Pasión, Murciana, Selene, and Dorada) obtained from different crosses between apricot varieties and three traditional Spanish cultivars (Currot, Mauricio, and Búlida), were separated according to flesh color into four groups: white, yellow, light orange, and orange (mean hue angles in flesh were 88.1, 85.0, 77.6, and 72.4, respectively). Four phenolic compound groups, procyanidins, hydroxycinnamic acid derivatives, flavonols, and anthocyanins, were identified by HPLC-MS/MS and individually quantified using HPLC-DAD. Chlorogenic and neochlorogenic acids, procyanidins B1, B2, and B4, and some procyanidin trimers, quercetin 3-rutinoside, kaempferol 3-rhamnosyl-hexoside and quercetin 3-acetyl-hexoside, cyanidin 3-rutinoside, and 3-glucoside, were detected and quantified in the skin and flesh of the different cultivars. The total phenolics content, quantified as the addition of the individual compounds quantified by HPLC, ranged between 32.6 and 160.0 mg 100 g(-1) of edible tissue. No correlation between the flesh color and the phenolic content of the different cultivars was observed.

Murcott seedless: influence of gamma irradiation on citrus production and fruit quality

“…correspond to flavanone glycosides, followed by flavones, flavonols and the fully polymethoxylated flavones (PMFs) (Ruiz et al, 2005;Nogata et al, 2006;Weber et al, 2006;Mata-Bilbao et al, 2007). Our results were comparable with several latest reports in mandarin and oranges varieties, and our previous studies on the pulp and rind of orange and mandarin species indicated that the Satsume group present the highest amounts of flavanone glycosides, hesperidin and narirutin, compared to the other varieties studied (Cano et al, 2008;Bermejo et al, 2011a,b;Rojas-Argudo et al, 2012).…”

The effect of solvent extraction on antioxidant properties of apricot fruit

“…The antioxidant profile of apricot fruit (Prunus armeniaca L.) has recently been analysed with particular reference to the total antioxidant capacity, polyphenols and carotenoids [5][6][7][8][9]. Given that a diverse germplasm exists for this species, the effect of the genotype on antioxidant properties has been considered, and the nutraceutical profiles of many cultivars have been studied in order to find outstanding genotypes rich in antioxidant compounds [10][11][12].…”

“…The total antioxidant capacity of this fruit has been measured, especially in the hydrophilic fruit extracts, which mainly contain polyphenols and vitamins. Many phenols have been identified in apricots [8,15,16] that are also known to be a rich source of carotenoids, which are important compounds for the eyes and skin. Recent investigations of the antioxidative effect of carotenes such as phytoene and phytofluene have suggested that they may be part of the oxidative stress defence system in human tissues [17,18].…”

Influence of postharvest processing and storage on the content of phenolic acids and flavonoids in foods

“…Quercetin-3-rutinoside, kaempferol-3-rhamnosyl-hexoside and quercetin-3-acetyl-hexoside were found only in the peel tissue of apricots from different cultivars [187]. Small amounts of kaempferol (27 l 2 lg/kg edible fruit pulp) occur only in the pulp of the cactus pear [191].…”
