Nutritional and Biological Evaluation of Leaves of Mangifera indica from Mauritius

Abstract

Mango trees are evergreen plants that are present all around Mauritius. In this study, mango leaves, Mangifera indica grown in Mauritius were investigated for their nutritional values involving proximate composition, total flavonoid (TFC), total phenolic (TPC), and mineral content, and phytochemicals as well as its antioxidant and antibacterial properties. e ash, crude fat, neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) of the mango leaves were found to be 12. 61, 3.92, 35.32, 34.98, and 12.86%, respectively. e calcium content (2.15%) was above the normal required range, while the phosphorus content (0.12%) and crude protein content (13.60%) were within the normal required range of common fodders. e phytochemical results showed the presence of saponins, alkaloids, phenols, tannins, and flavonoids in the crude, EtOAC, and MeOH extracts. e values of TPC and TFC were higher for the EtOAC extract compared to the MeOH extract. Several secondary metabolites were identified from the leaves of the Mangifera indica which include 11 phenols, 4 xanthones, 9 flavanols, 10 benzophenones, 7 terpenoids, and 4 derivatives of gallotannins using UPLC-MS/MS. e presence of these metabolites is responsible for good antioxidant and antibacterial properties. Hence, mango leaves can be exploited for its potential use as a supplementary fodder for ruminants.

Metabolomic Profiling of Mango (Mangifera indica Linn) Leaf Extract and Its Intestinal Protective Effect and Antioxidant Activity in Different Biological Models

“…The quantification of the content of phenolic (TPC) in MIE demonstrated that the extract contained high amounts of polyphenols. The TPC of the extract was higher than in previous studies from India [39], Thailand [40], Mauritius [26], and Brazil [21].…”

“…UHPLC chromatograph of MIE showed the presence of mangiferin, quercetin, gallic acid, vitamin C, and carotenoids which have a good capacity of capturing radicals [38]. The extract provided a high antiradical activity dose-dependently inhibiting the radical DPPH and ABTS at low concentrations, when compared with other studies [26,39,40]. Moreover, the FRAP assay also demonstrated that MIE has a high reducing power at low concentrations.…”

In-silico analysis of the inhibition of the SARS-CoV-2 main protease by some active compounds from selected African plants

“… 1 , 15 In vitro and in vivo studies on mangiferin, a C-glucosyl xanthone, have revealed various pharmacological activities that include antiviral properties. 35 , 36 , 59 , 60 The binding affinities between the active compounds (ligands) and Mpro in this study were stabilized by non-covalent interactions, such as hydrogen bonds, hydrophobic bonds, pie–stack interactions, and salt bridge formation ( Figure 3 and Table 3 ). Similarly, Mohapatra et al.…”

Mango (Mangifera indica L.) Leaves: Nutritional Composition, Phytochemical Profile, and Health-Promoting Bioactivities

“…These can be utilized as an alternative source of livestock feeding in developing countries for alleviating food shortage for livestock. Proximate composition of MLs showed 13.6% of CP in dauphiné Mauritian variety, 20.38% CP in Nigerian variety, and 6.90% CP in Laos variety [13]. Varietal difference of leaf protein was also studied in five different cultivars of mango (Pusa Arunima, Pusa Surya, Amrapali, Mallika, and Dushehari) grafted on three different rootstocks (K-5, Kurakkan, and Olour), and it was found that Amrapali on K-5 rootstock has higher leaf protein (146.47 mg g −1 fresh weight) followed by Amrapali on Olour rootstock (145.22 mg g −1 fresh weight).…”
