Investigation on the Antioxidant Activity of Leaves, Peels, Stems Bark, and Kernel of Mango (Mangifera indica L.)

Abstract

Bioactive polyphenols, cartenoids, and anthocyanins present in fruits and vegetables are receiving much attention because of their potential antioxidant activity. This study was conducted to determine antioxidant activity of leaves, peels, stem bark, and kernel of mango varieties langra and chonsa. Total phenolic (TPC) and total flavonoid contents (TFCs) in segments of langra ranged from 63.89 to 116.80 mg GAE/g DW and 45.56 to 90.89 mg CE/g DW, respectively, and that of chonsa were 69.24 to 122.60 mg GAE/g DW and 48.43 to 92.55 mg CE/g DW, respectively. The 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and linoleic inhibition capacity in segments of langra ranged from 53.30% to 61.10% and 40.0% to 47.20%, respectively, whereas for chonsa; 56.40% to 66.0% and 48.1% to 49.0%, respectively. The reducing potentials of different segments of langra and chonsa at concentration of 10 mg/mL were 0.512 to 0.850 and 0.595 to 0.665 mV, respectively. Comparison between both varieties showed chonsa exhibited better antioxidant activity. Data were analyzed by analysis of variance (ANOVA) using completely randomised design (CRD) under factorial.

In vitro Antioxidant Activities of Trianthema portulacastrum L. Hydrolysates

“…The methanol extract used in the current study results in a similar yield to that of fruits, as reported by our group (20,21), and that of Lantana camara (12.68%), as reported by Ali-Emmanuel et al (22). Together, these results indicate that acidified methanol is a suitable choice for the recovery of phenolic antioxidants.…”

“…However, the FRP values of T. portulacastrum reported in this study are comparable with previously published values from certain Brazilian vegetables (29) and fruits (21), but lower than values from medicinal plants investigated by Sultana et al (30). …”

Response Surface Methodology for Ultrasound-Assisted Extraction of Astaxanthin from Haematococcus pluvialis

“…The extraction of active ingredients from Haematococcus pluvialis can be carried out in various ways, such as maceration extraction, solid-phase microextraction and hydrodistillation [9,10]. Usually, these conventional extraction methods are time- and solvent-consuming.…”
