“…The remaining lilies had the lowest, having similar TPCs. The results showed that the TPCs of different genotype lilies varied greatly, which coincides with results from potato in which cultivar was the main variable affecting the biosynthesis of the studied phenolics [34]. The TFCs of the different lilies tested showed a similar trend with the TPCs, but with some differences.…”

The genus Lilium contains more than 100 wild species and numerous hybrid varieties. Some species of them have been used as medicine and food since ancient times. However, the research on the active components and the medical properties of lilies has only focused on a few species. In this study, the total phenolic acid content (TPC), total flavonoid content (TFC), and antioxidant capacity of 22 representative lilies were systematically investigated. The results showed that the TPC, TFC and antioxidant activity were highly variable among different lilies, but they were significantly positively correlated. Hierarchical cluster analysis indicated that L. henryi and L. regale were arranged in one group characterized by the highest TPC, TFC and antioxidant capacity, followed by Oriental hybrids and Trumpet and Oriental hybrids. The traditional edible and medicinal lilies were clustered in low TPC, TFC and antioxidant capacity group. A total of 577 secondary metabolites, including 201 flavonoids, 153 phenolic acids, were identified in the five species with great differences in antioxidant capacity by extensive targeted metabonomics. Differentially accumulated metabolites (DAMs) analysis reviewed that the DAMs were mainly enriched in secondary metabolic pathways such as isoflavonoid, folate, flavonoid, flavone, flavonol, phenylpropanoid, isoquinoline alkaloid biosynthesis, nicotinate and nicotinamide metabolism and so on. Correlation analysis identified that 64 metabolites were significantly positively correlated with antioxidant capacity (r ≥ 0.9 and p < 0.0001). These results suggested that the genus Lilium has great biodiversity in bioactive components. The data obtained greatly expand our knowledge of the bioactive constituents of Lilium spp. Additionally, it also highlights the potential application of Lilium plants as antioxidants, functional ingredients, cosmetic products and nutraceuticals.

“…The responses observed in this study showed a greater influence of the genotype on the treatments applied, as has been reported by numerous authors who attribute the differences in antioxidant activity and the content of phenolic and carotenoid compounds in potatoes to a wide genotypic variation (Andre et al, 2007;Reddivari et al, 2007;Lachman et al, 2012;Tierno et al, 2016;Oertel et al, 2017;Cuéllar-Cepeda et al, 2019). Rytel et al (2014) in processed yellow and colored potato tubers of Czech Republic, and Gutiérrez-Quequezana et al (2020) in whole purple potato tubers of Switzerland. The total contents of chlorogenic, cryptochlorogenic, and neochlorogenic acids were lower in the cultivars Criolla Colombia, Paola and Milagros than in the cultivar Violeta that attained values between two and five times higher.…”

La papa es una buena fuente de compuestos con alta actividad antioxidante como los ácidos fenólicos, las antocianinas y los carotenoides, cuyos contenidos se pueden ver afectados por prácticas agronómicas como la fertilización. El presente estudio evaluó el efecto de la fertilización foliar con magnesio y manganeso sobre el contenido de compuestos fenólicos, antocianinas y carotenoides, y la actividad antioxidante en tubérculos cocidos de cuatro cultivares de papa del Grupo Phureja. Se determinó la actividad antioxidante y el contenido de fenolestotales, antocianinas totales, ácidos fenólicos y carotenoides. El cultivar Violeta presentó los mayores contenidos de fenoles totales y la mayor actividad antioxidante. Se observó un efecto significativo de la fertilización con magnesio, que aumentó el contenido de fenoles totales en el cultivar Criolla Colombia y lo redujo en los cultivares Violeta y Milagros. Estos resultados sugieren alta influencia del genotipo sobre la respuesta de las variables evaluadas. Como consecuencia, el cultivar Violeta es recomendado para el estudio de actividad antioxidante in vivo, teniendo en cuenta que mostró los mayores valores, comparado con los demás cultivares.

The purpose of this study was to characterize the peels of a CN1 somatic hybrid obtained from two dihaploid potato lines (Cardinal H14 and Nicola H1) in terms of the health‐promoting phenolic compounds (phenolic acids and anthocyanins). The CN1 hybrid is defined by a pink tuber skin color making it different from the light‐yellow‐skinned “Spunta,” which is the most commonly grown potato cultivar in Tunisia. Oven‐dried peel samples derived from CN1 hybrid and cv. Spunta were ground, and phenolic compounds were extracted with water or methanol for quantification. Lyophilized peels were used for the phenolic acid and anthocyanin analyses. Higher total quantities of phenolic compounds were recovered in methanol extracts compared with water extracts. A slightly higher concentration of phenolic acids (100 mg/100 g DW) was obtained in the lyophilized peels extract of CN1 hybrid than in the cv. Spunta corresponding sample (83 mg/100 g DW). The profiles of the chlorogenic acid isomers were almost identical in both of CN1 hybrid and cv. Spunta. Caffeic acid (CA) and three caffeoylquinic acids (CQAs): 3‐CQA, 4‐CQA, and 5‐CQA, were identified from both genotypes, 5‐CQA being the dominant form in both potatoes. Since the CN1 hybrid has a pink skin color, its anthocyanin profile was also determined. The anthocyanin quantity in the CN1 peels was 5.07 mg/100 g DW, involving six different anthocyanins that were identified within the extract, namely, Pelargonidin‐3‐rutinoside‐5‐glucoside, peonidin‐3‐rutinoside‐5‐glucoside, coumaroyl ester of pelargonidin‐3‐rutinoside‐5‐glucoside, coumaroyl ester of peonidin‐3‐rutinoside‐5‐glucoside, feruloyl ester of pelargonidin‐3‐rutinoside‐5‐glucoside, and feruloyl ester of peonidin‐3‐rutinoside‐5‐glucoside. These results suggest that the peel waste of CN1 somatic hybrid can be considered as a promising source of high‐value compounds for food industry.
