Abstract

Myrciaria floribunda, also known as rumberry, is a tree native to the Brazilian Atlantic Forest, where its fruits have the potential for commercial use. This study evaluates the antioxidant potential, determines the phytochemical profile, and chemically characterizes the rumberry fruit. Accessions were sampled from the Rumberry Active Germplasm Bank of the Federal University of Alagoas, Brazil. Physical characteristics, chemical characteristics, and phenolic compound content were analyzed. Chemical profile characterization was carried out using PSMS. Accessions had an average weight of 0.86 g. Accession AC137 presented a higher pulp yield (1.12 g). AC132 and AC156 had larger fruits, AC137 showed greater firmness (5.93 N), and AC160 had a higher and total phenolic content ratio (279.01 ± 11.11). Orange-colored accessions scored higher in evaluated parameters, except for AC160 for phenolic content. Thirty-two compounds were identified on positive ionization mode and 42 compounds on negative ionization mode using PSMS. Flavonoids, followed by the derivatives of benzoic acid, sugars, and phenylpropanoids, were the most prominent. Myricitrin, quercitrin, and catechin stand out as flavonoids that have been reported in previous studies with antioxidant and antimicrobial properties, in addition to health and therapeutical benefits, demonstrating the potential of the rumberry fruit.

Highlights

Myrtaceae is one of the most representative families of Angiosperms, distributed throughout Australia, South America, Tropical America, and Southeast Asia, though mainly found in tropical and subtropical regions
Results show the fruits had an average weight of 0.86 g, with a variation of Fruit weight (FW) from 0.56 to 1.32 g, for seed weight (SW), the value ranged from 0.13 to 0.30 g, while pulp weight (PW) ranged from 0.42 to 1.12 g

Summary

Introduction

Myrtaceae is one of the most representative families of Angiosperms, distributed throughout Australia, South America, Tropical America, and Southeast Asia, though mainly found in tropical and subtropical regions. In Brazil, the family is considered one of the most economically important, occupying the eighth position regarding the number of species. Brazil stands out as one of the largest producers of fresh fruit. It has a sizeable territorial extension with favorable climatic conditions for producing native and exotic fruit species, among them the rumberry, known as cambuí natively. Many native species are still unknown to the general public but have great economic potential for fresh or processed fruit marketing. Among the native fruits with great potential for industrialization is the rumberry (Myrciaria floribunda). The Brazilian name “cambuí” is of indigenous origin, meaning “shedding leaf”, a designation given to specimens belonging to the genera Myrcia and Myrciaria [1,2]
