Anthocyanins in berries of Maqui [Aristotelia chilensis (Mol.) Stuntz]

Abstract

The anthocyanin composition of berries of Maqui [Aristotelia chilensis (Mol.) Stuntz] was determined by HPLC with photodiode array and MS detection. Eight pigments corresponding to the 3-glucosides, 3,5-diglucosides, 3-sambubiosides and 3-sambubioside-5-glucosides of delphinidin and cyanidin were identified, the principal anthocyanin being delphinidin 3-sambubioside-5-glucoside (34% of total anthocyanins). The average total anthocyanin content was 137.6 +/- 0.4mg/100g of fresh fruit (211.9 +/- 0.6 mg/100g of dry fruit). The relative high anthocyanin content and the important presence of polar polyglycosylated derivatives makes the fruits of A. chilensis an interesting source of anthocyanin extracts for food and pharmaceutical uses.

Polyphenol content and antioxidant activity of maqui (Aristotelia chilensis Molina Stuntz) during fruit development and maturation in Central Chile

“…Maqui fruit phenolic extracts have also shown antioxidant activity in-vivo (Céspedes et al, 2008). The main compounds in maqui fruits are phenolic acids, flavonols (quercetin, rutin, myricetin), flavanols (catechins, epicatechin), and eight anthocyanins (Escribano-Bailón et al, 2006;Céspedes et al, 2010;Schreckinger et al, 2010;Rojo et al, 2012).…”

Antioxidant Activity of an Unusual 3-Hydroxyindole Derivative Isolated from Fruits of Aristotelia chilensis (Molina) Stuntz

“…Previously, we have reported the alkaloid composition of the leaves of Aristotelia chilensis (Céspedes et al, 1993;Silva et al, 1997). There are some reports about the antioxidant activity and a partial composition of anthocyanidins (Miranda-Rottman et al., 2002;Escribano-Bailon et al, 2006).In continuation of our search for more specifi c antioxidant activities, in the present paper we report the antioxidant activity of an unusual 3-hydroxyindole derivative and of a very interesting fraction obtained during a metabolomic analysis of fruits of A. chilensis. The occurrence of 3-hydroxyindole helps us to explain the antioxidant, chemopreventive, cardiopreventive, and anti-infl ammatory activities of this fruit.…”

HYDROXYCINNAMIC ACID DERIVATIVES AND FLAVONOL PROFILES OF MAQUI (Aristotelia chilensis) FRUITS

“…Despite the extensive research, the profiles of flavonols and hydroxycinnamic acid derivatives (HCAD S ) and their concentrations in maqui berries has not been documented. Prior research has focused primarily on the high anthocyanin content of this fruit 4,8 . The anthocyanin profile of maqui berries has been described, indicating the presence of 3-glucoside, 3,5-diglucoside, 3-sambubioside, and 3-sambubioside-5-glucoside derivatives of delphinidin and cyanidin 4,8 , with a total anthocyanin concentration of 137.6 ± 0.4 mg/100 g-fresh weight 4 .…”

“…The fruit of this tree is an edible berry with a diameter of 5 mm, which contains 2 seeds, where the pulp is intensely coloured. Maqui fruits have been traditionally used as a colorant as well as in natural medicine 3 and maqui has thus been the topic of numerous studies 1,[4][5][6][7][8][9][10][11][12] . Despite the extensive research, the profiles of flavonols and hydroxycinnamic acid derivatives (HCAD S ) and their concentrations in maqui berries has not been documented.…”
