Viburnum mullaha D. DON fruit (Indian cranberry): A potential source of polyphenol with rich antioxidant, anti-elastase, anti-collagenase, and anti-tyrosinase activities

摘要

Viburnum mullaha (Buch.-Ham. Ex D. Don), is an underexplored wild edible fruit of Indian Himalayan region, analyzed for total polyphenol contents, antioxidant, anti-elastase, anti-collagenase, and anti-tyrosinase activities using in vitro assays. High values of total phenolic contents of 1257 ± 40 mg gallic acid equivalents/100 g fruit weight and total flavonoid contents of 3501 ± 203 mg catechin equivalents/100 g fruit weight were observed. V. mullaha fruit extracts showed outstanding antioxidant activities (ABTS~(+), 1,1-diphenyl-2-picrylhydrazyl, superoxide anion, linoleate peroxyl radicals scavenging, and ferric reducing activities) and remarkable anti-elastase, anti-collagenase, and anti-tyrosinase activities. High resolution liquid chromatography–mass spectroscopy analysis revealed presence of 15 phenolic compounds, namely, chlorogenic acid, acetyl salicylic acid, dihydrorobinetin, dihydromyricetin, 2-isoprenylemodin, rutin, cosmosiin hexaacetate, pectolinarin, dihydroquercetin, eriodictyol, iriginol hexaacetate, theaflavin, epicatechin-pentaacetate, lomatin, and peucenin in fruit extracts. This study recommends utilization of V. mullaha fruit as functional food with prospective pharmaceutical, nutraceutical, and cosmeceutical properties.
