Bioactive compounds and antioxidant activity of jabuticaba var. Pingo de mel during its physiological development

Abstract

The bioactive compounds and in vitro antioxidant activity of jabuticaba fruits var. Pingo de mel were evaluated during their physiological development. The fruits were harvested ten days after anthesis until maturity, at intervals of four days between collections. The period between anthesis and maturity was 34 days. Higher phenolics levels, hydrolysed tannins, and antioxidant activity were observed in 10 days after anthesis, while vitamin C contents were higher throughout the ripening process. At the end of development (34 days), higher levels of vitamin C and lower hydrolysed tannin were observed. Ot is known that the lower the hydrolysed tannins, the better the sensory characteristics of the fruit, and considering the benefits of vitamin C, it is necessary to harvest the jabuticaba fruits var. Pingo de mel in 34 days after anthesis for better use of these compounds.

Herbicide induced changes in nutrient and antinutrient content during mung bean (Vigna radiata L.) seed development

“…The mean antioxidant activity regardless of assay techniques used, reached maximum at the initial day of observation followed by gradual decline throughout the experimental period. The higher antioxidant activity on 10 DAFS as noticed in the present study is supported by the observation of Garcia et al, (2019) [10] , who reported that fruits during its physiological development registered higher total phenol and antioxidant activity on 10 days after anthesis. Several lines of evidence indicate that antioxidant activity of a sample is related to phenolic compounds present in the sample (Fidrianny et al,2015) [9] .…”
