Abstract

Temperate fruit species, originate from regions with cold winters and well-defined climatic seasons. These fruits are also produced in subtropical and tropical regions. The aim of this study was to determine the bioactive compounds and antioxidant activity of different fruit cultivars from fruit trees of temperate climate, such as peach, pear, quince, and fig, able to be produced in subtropic regions. Analyzes of antioxidant activity, total phenolics and ascorbic acid were carried out. In peaches, ‘Biuti’ had the highest phenolic content, and ‘Bonão’ stood out in relation of antioxidant activity (ABTS) and ascorbic acid. For quinces, 'Lageado' had higher phenolic content, ‘Provence’ and ‘CTS’ showed higher antioxidant activity (ABTS), and ‘Alaranjado’ stood out in relation of antioxidant activity (DPPH). ‘Fuller’, ‘Smyrna’ and ‘Portugal’ are the ones with the highest levels of ascorbic acid. In pears, ‘Seleta’ showed the highest phenolic content, antioxidant activity (DPPH) and ascorbic acid. ‘Centenaria’ presented the highest antioxidant activity (ABTS). In figs, ‘Três num Prato’, ‘Lemon’ and ‘Brunswick’ had the highest ascorbic acid content. ‘Três num prato’ and ‘Roxo de Valinhos’ showed the highest phenolic content and antioxidant activity consecutively. It was found that cultivars of these evaluated fruits showed great variability, even under similar conditions.

Highlights

Temperate fruit species originate from regions with cold winters and well-defined climatic seasons, which are characterized by providing ideal temperatures for growth during spring and summer
The domestication of most temperate fruit trees began in Europe and Asia, but recently their cultivation has extended to non-traditional areas in tropical and subtropical regions around the world, with mild, dry winters and hot and rainy summers (Barbosa et al, 2010, Pio et al, 2019)
The peach tree (Prunus persica (L.) Batsch) produces fruit with a very pleasant aroma and color that fits the list of economically important fruits, because of its exotic appearance, and because it is an excellent source of bioactive compounds, (Cantín et al, 2009) like phenolic compounds (35.97 mg/100 g) and carotenoids (Legua et al, 2011)

Summary

Introduction

Temperate fruit species originate from regions with cold winters and well-defined climatic seasons, which are characterized by providing ideal temperatures for growth during spring and summer. The domestication of most temperate fruit trees began in Europe and Asia, but recently their cultivation has extended to non-traditional areas in tropical and subtropical regions around the world, with mild, dry winters and hot and rainy summers (Barbosa et al, 2010, Pio et al, 2019). There is an enormous market potential, since national production has not yet reached sufficient volume to meet domestic demand For this reason, several measures have been taken, mainly in relation to peach production in subtropical and tropical regions (Souza et al, 2013). Several measures have been taken, mainly in relation to peach production in subtropical and tropical regions (Souza et al, 2013) This fruit tree has an area of approximately 17.60 ha and reaches productivity of 12.5 ton/ha (Instituto Brasileiro de Geografia e Estatística, 2020)
