Polyphenol and Ellagitannin Constituents of Jabuticaba (Myrciaria cauliflora) and Chemical Variability at Different Stages of Fruit Development

Abstract: A new ellagitannin named cauliflorin (1), seven known hydrolyzable tannins (2-8), and six known phenolics (9-14) were isolated from jabuticaba. Compounds 2-8 had not been previously isolated from M. cauliflora fruits. The jabuticaba fruit was analyzed at four developmental stages for ellagitannins 1, 3, 7, and 8, phenolic acids 11 and 12, anthocyanins, organic acids, and sugars via HPLC-UV-DAD and NMRq. The content of ellagitannins and organic acids declined during fruit development, whereas at full ripeness s… Show more

“…Popularly known as “jabuticaba,” the fruit is consumed fresh or used for the production of liqueur, vinegar, wine, juice, jam, and jelly [6]. Several phenolic compounds, including flavonoids and anthocyanins, are present in the fruit peel of P. cauliflora that exert numerous biological effects [7]. Several pharmacological studies have been conducted using different extracts that were obtained from fruit peels of this species, highlighting its antioxidant [8], hypotensive [9], anti-obesity [10], anti-inflammatory [11], hypolipidemic [12], and antibacterial [13] activity.…”

“…The extraction process was conducted in duplicate for each sample. Total phenols, flavonoids, total tannins, in addiction to hydrolysable and condensed tannins were quantified according to techniques described in Pereira et al (2017).…”

“…Sandy soils (sand average value 490 g/kg) with low nutrient levels (elagitaninos) foram detectados e tentativamente identificados com base em LC-TOF/MS(ALEZANDRO et al, 2013;PLAZA et al, 2016), embora não tenham apresentado consistência com outros estudos que utilizaram técnicas tradicionais de isolamento e identificação(PEREIRA et al, 2017; WU et al, 2012;WU et al, 2013). Em outro estudo, oito elagitaninos, incluindo a inédita cauliflorina (1), e seis polifenóis foram isolados e identificados(PEREIRA et al, 2017). Glicose, frutose, sacarose e ácido cítrico foram quantificados por RMN H 1 quantitativo(PEREIRA et al, 2017).…”

Glicose, frutose, sacarose e ácido cítrico foram quantificados por RMN H 1 quantitativo(PEREIRA et al, 2017). Para a análise dos macro e micronutrientes das amostras foi utilizada a espectrometria de absorção atômica (Ca 2+ , Mg 2+ , Cu 2+ , Fe 3+ , Mn 2+ , Zn 2+ ), espectrometria na região do visível (P) e espectrometria de emissão em chama (K + ).…”
