Anthocyanins and antioxidant capacities of six Chilean berries by HPLC–HR-ESI-ToF-MS

Maesa indica: a nutritional wild berry rich in polyphenols with special attention to radical scavenging and inhibition of key enzymes, α-amylase and α-glucosidase

“…The chloroform extracts of fruit exhibited higher flavonoid content (21.33 g RE/100 g extract) compared to the other solvent extracts. Previous reports from the other berry fruits such as blackberry, highbush blueberries, murta, calafate, arrayán, chequén, and meli contained lower amount of phenolics and flavonoid compounds when compared to fruits of M. indica (Ramirez et al 2015). Polyphenols (phenolics, tannins and flavonoids), extensively dispersed in plants have gained much attention due to their anti-mutagenic, antitumor, antioxidant, anti-diabetic, and free radical scavenging abilities which potentially have beneficial implications for human health (Davis et al 2009).…”

“…Acetone extract of M. indica fruit show maximum capability of ferric reducing, chelating metal ions and phosphomolybdenum reduction activities. The results of other berry fruits showed the minimum amount of activity especially, the fruits of Vaccinium corymbosum (Highbush blueberries), Luma chequén, Luma apiculata, Ugni molinae, Royle berry and Amomyrtus meli shows minimum amount of ferric reducing property when compared to this M. indica fruits (Ramirez et al 2015;Pradhan and Saha 2015).…”

Anthocyanin profile of red fruits and black carrot juices, purees and concentrates by HPLC‐DAD‐ESI/MS‐QTOF

“…These compounds have also been reported by other authors as Ramirez et al . (), but they did not quantify them. Of all compounds, malvidin‐3‐glucoside (peak 31, Table ) is the prevalent anthocyanin and it is present in blueberries in a higher concentration than those reported by other authors (Mueller et al ., ) who reported concentrations of malvidin‐3‐glucoside of 4.50 mg/100 mL in juice, or Giovanelli & Buratti () who found 20.7 mg/100 g of this anthocyanin.…”

“…In addition, a compound only previously described by Ramirez et al . () was found: delphinidin‐3‐(6′cumaroil)‐glucoside (peak 47, Table ). It was identified by its M + at m/z 611 that after MS–MS analysis gave a fragment at m/z 303 corresponding to delphinidin.…”

Anthocyanins profiling of Thymus praecox opiz subsp. caucasicus var. caucasicus

“…One of the two peaks numbered 8 and 9 may be peonidin according to these reports which identified peonidin besides pelargonidin and cyanidin in this genus. Since the chromatographic peak order of peonidin is between pelargonidin and malvidin in some reports, it can be tentatively concluded the peak number 8 may be peonidin (Pazmino-Duran et al, 2001;Ramirez et al, 2015;Wang et al, 2003).…”
