“…with 93.18 ± 8.66 and 56.83 ± 0.60 mg GAE/100 g FW, respectively. Most of the literature about PCs in these fruits, as well as in many other plant foods, considered the EPCs as the total phenolics, underestimating the content of NEPCs Mertz et al, 2009;Palafox-Carlos et al, 2012a). The NEPCs are represented by HT and CT, or those PC with higher molecular weight associated to DF or protein within the food matrix ).…”

The presence of dietary fiber (DF) in the food matrix of some tropical fruits plays an important role in the release and absorption of its bioactive compounds, such as phenolic compounds (PCs). The aim of this study was to evaluate the effect of the DF fractions in mango cv. ' Ataulfo' , papaya cv. 'Maradol' and pineapple cv. 'Esmeralda' , on the bioaccessibility of their PCs and antioxidant capacity (ADXC) under an in vitro digestion model. The highest PCs content and ADXC was found in mango (274.30 mg GAE/100 g FW), followed by papaya (212 mg GAE//100 g FW), and pineapple (107.63 mg GAE/100 g FW), respectively. About 50% of the total PCs in all fruits was released at gastric phase, increasing closer to 60% at intestinal phase in mango and pineapple. However, the highest content of PCs associated to DF was found in mango (2.48 mg GAE/100 g FW) compared with papaya DF fractions (0.96 GAE/100 g FW) and pineapple (0.52 GAE/100 g FW). The presence of DF in mango, papaya and pineapple did not represent a major limitation on the bioaccessibility of its PCs according to the in vitro digestion model used in this study.

“…Polyphenols are scavengers of a wide variety of reactive species such as superoxide, hydroxyl radical, peroxyl radical, hypochlorous acid, and peroxynitrous acid, resulting in less reactive radicals (Wang and Jiao, 2000;Mertz et al, 2009). Different methods exist to evaluate the AA (Gil et al, 2000;Mermelstein, 2008), both in vitro or in vivo.…”

Maqui (Aristotelia chilensis [Molina] Stuntz, Elaeocarpaceae) is a Chilean native species which produces small berries that are mainly collected from the wild. The health benefits of maqui fruit are attributed to their high polyphenol content as well as their wide variety of anthocyanins and flavonols. One of the main factors that affect the polyphenol content in fruit is the maturity stage at harvest. The objective of this study was to determine total phenol and total anthocyanin content and antioxidant activity (by ferric reducing ability of plasma [FRAP] assay) of maqui fruits harvested at different fruit maturity stages from two wild populations located in Central Chile. Each maturity stage was determined by days from fruit set, berry size, and soluble solids. Total phenol content declined while total anthocyanin content increased from the green to light red stage. Nevertheless, both total phenol and anthocyanin content increased from the light red to dark purple stage. The highest anthocyanin content and antioxidant activity was found in the late maturity stage (dark purple). The results show that ripening in maqui fruit can be expected with 1100 growing degree-days (91 d after fruit set) in Central Chile. At this moment of harvest, fruits with 18-19 °Brix have the highest anthocyanin content and antioxidant activity (FRAP). This study constitutes the first advances in the understanding of maqui fruit ripening and corresponding antioxidant activity.

“…Here, the higher content found is in accordance with the stage of production of older trees at the moment of collection. Moreover, the high content of carotenoids may be connected to photo protection process against oxidative damage in function of the adaptability to climate (Taiz and Zeiger, 2008;Mertz et al, 2009). It is worth to note that there is a tendency to recover this metabolite from the leaves instead of seeds, since the amount of this metabolite was very close to lower detection limit by the method used.…”

Abstract. Annona squamosa L. has been recognized by having compounds with important in vitro biological activity against human disease or as insecticide. However, knowledge of the antiviral potential and micro molecules production of A. squamosa L. at different phenological stages is scarce. The secondary metabolites detection and biological activity from seeds and leaves in 4 and 14 years old trees from semi arid region were performed. Phytochemical identification was obtained by chemical bioprospection and histochemical localization in leaves and seeds'. Seeds acids content was analyzed by gas chromatography. Cytotoxic effect and antiviral activities against equine and suid herpesvirus were also performed. Results showed differences in the amount of flavonoids, carotenoids, and phenolic compounds between leaves and seeds and by stage of production. Carotenoids and phenolic compounds, especially tannins, were higher in older trees' leaves. Fat acids detected in seeds were oleic, linoleic arachidic, Cis-11-eicosenoic, elaidic and palmitoidic acids. Cytotoxicity was higher in hydrophobic than hydroalcoolic extracts. Broad spectrum antiviral activity was more marked for younger trees' aqueous extract. The high chemical adaptability of A. squamosa to semi arid environment was evident and the identification of A. squamosa secondary metabolites regarding the plant senescence may guide a better utilization of plant organs in order to obtain substances of pharmacological interest.
