Summary, etc. |
<p>The current study explored the therapeutic significance of different standardized citrus peel extracts as potential neuroprotective agents using integrated <em>in vitro</em> and <em>in silico</em> approaches. Hydroethanolic extract of five industrially important citrus fruit peels were subjected to HPLC-based quantification of estimating major flavonoids of nutraceutical importance. Pharmacological activities like antioxidant and anti-inflammatory activities of the extracts were determined by <em>in vitro</em> assays. Further, The identified bioactive metabolites were subjected to the Prediction of Activity Spectra for Substances program to get a prediction of their biological activity spectrum. Amongst various solvent combinations, 80% ethanol provided maximum (≥ 20% w/w) extract yield. Mandarin peels of <em>Citrus reticulata</em> showed the highest amount of polyphenolics (<em>Citrus reticulata </em>Blanco; 42.24 ± 0.57 mg gallic acid equivalent/g) and flavonoids (<em>Citrus reticulata c.v</em>.;13.08 ± 0.17 mg quercetin equivalent/g) content. The most abundant flavonoid compound present in all the citrus peel was hesperidin, except <em>Citrus reticulata </em>Blanco and <em>Citrus grandis</em>, which showed a considerably high amount of nobiletin and naringin, respectively. <em>Citrus reticulate c.v. </em>peel extract showed potent antioxidant [IC<sub>50</sub><sub> </sub>= 118.82 ± 1.97 µg/mL in 2,2-diphenyl-1-picrylhydrazyl assay and IC<sub>50 </sub>= 138.12 ± 2.67 µg/mL in 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid assays)], anti-inflammatory (IC<sub>50 </sub>= 50.61 ± 6.79 µg/mL), and acetylcholinesterase inhibitory ((IC<sub>50 </sub>= 130.61 ± 2.04µg/mL) activities compared to the other extracts.<em> In silico</em> assessment revealed a high (Pa > 0.7) activity score for free radical scavenging, lipid peroxidase inhibitory, membrane integrity agonistic, anti-inflammatory, antioxidant, and several other important biological activities of the identified flavonoids in the extracts, thus supported neuroprotective potential. Citrus flavonoids naringin, rutin, and tangeretin showed high activity scores for anti-inflammatory activity strengthening the results of <em>in vitro</em> assay. These potentials of citrus peels could be utilized in the development of functional foods and nutraceuticals for neurodegenerative conditions. Furthermore, such a practice will help citrus agro-industrial waste valorisation.</p> |
