Nutr."],"abstract":"<jats:p>A comparative study was conducted among the flesh (SOF) and pericarp (SOP) of <jats:italic>Stauntonia obovatifoliola<\/jats:italic>, a wild edible fruit in China. The nutrient composition of both these tissues was firstly quantified, and liquid-liquid extraction was then used to separate their methanolic extracts to get petroleum ether, chloroform, ethyl acetate, n-butanol, and residual aqueous fractions, which were evaluated for their total phenol content (TPC), total flavonoid content (TFC), antioxidant capacities, and \u03b1-glucosidase and acetylcholinesterase inhibition abilities. Finally, high-performance liquid chromatography (HPLC) was used to analyze their phytochemical composition. The results revealed the excellent nutritional properties of both SOF and SOP, especially SOP (total dietary fiber, 15.50 g\/100 g; total amino acids, 0.80 g\/100 g; vitamin C, 18.00 mg\/100 g; Ca, 272.00 mg\/kg; K, 402.00 mg\/100 g). For both tissues, their ethyl acetate fractions showed the highest TPC (355.12 and 390.99 mg GAE\/g DE) and TFC (306.58 and 298.48 mg RE\/g DE). Surprisingly, the ethyl acetate fraction of SOP exhibited the strongest DPPH and ABTS radical scavenging capacity with 1046.94 and 1298.64 mg Trolox\/g, respectively, which were higher than that of controls Vc and BHT. In contrast, their chloroform fractions exhibited the strongest ferric reducing antioxidant power (1903.05 and 1407.11 mg FeSO<jats:sub>4<\/jats:sub>\/g DE) and oxygen radical absorbance capacity (951.12 and 1510.21 mg Trolox\/g DE). In addition, the ethyl acetate fraction of SOF displayed superior \u03b1-glucosidase inhibition ability with the IC<jats:sub>50<\/jats:sub> value of 0.19 mg\/mL, which was comparable to control acarbose. In comparison, the ethyl acetate fraction of SOP had the best acetylcholinesterase inhibition ability with the IC<jats:sub>50<\/jats:sub> value of 0.47 mg\/mL. The HPLC analysis results demonstrated that the ethyl acetate fraction of SOP showed significantly higher phenolic content, particularly for phenolic acids (p-hydroxybenzoic acid, 8.00 \u00b1 0.65 mg\/g) and flavonoids (epicatechin, 28.63 \u00b1 1.26 mg\/g), as compared to other samples. The above results suggest that <jats:italic>Stauntonia obovatifoliola<\/jats:italic>, especially its pericarp, had excellent nutrient compositions, bioactive properties and phytochemical characteristics, and had the potential to be developed as natural functional food.<\/jats:p>","DOI":"10.3389\/fnut.2022.1013971","type":"journal-article","created":{"date-parts":[[2022,9,9]],"date-time":"2022-09-09T10:09:29Z","timestamp":1662718169000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["A comparative study of nutrient composition, bioactive properties and phytochemical characteristics of Stauntonia obovatifoliola flesh and pericarp"],"prefix":"10.3389","volume":"9","author":[{"given":"Rurui","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuerong","family":"Ru","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenxing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiahong","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuechun","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,9,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"111433","DOI":"10.1016\/j.fct.2020.111433","article-title":"Nanosystems of plant-based pigments and its relationship with oxidative stress","volume":"143","author":"Aguirre-Joya","year":"2020","journal-title":"Food Chem Toxicol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"4408","DOI":"10.3390\/ijms20184408","article-title":"Role of a rhoa\/rock-dependent pathway on renal connexin43 regulation in the angiotensin ii-induced renal damage","volume":"20","author":"G\u00f3mez","year":"2019","journal-title":"Int J Mol Sci."},{"key":"B3","doi-asserted-by":"publisher","first-page":"4444","DOI":"10.3390\/molecules25194444","article-title":"Bioactive compounds and health-promoting properties of pear (pyrus communis l) fruits","volume":"25","author":"Kolniak-Ostek","year":"2020","journal-title":"Molecules."},{"key":"B4","doi-asserted-by":"publisher","first-page":"8707","DOI":"10.3390\/ijms21228707","article-title":"New in vitro model of oxidative stress: Human prostate cells injured with 2,2-diphenyl-1-picrylhydrazyl (dpph) for the screening of antioxidants","volume":"21","author":"Galasso","year":"2020","journal-title":"Int J Mol Sci."},{"key":"B5","doi-asserted-by":"publisher","first-page":"315","DOI":"10.3390\/foods10020315","article-title":"Perilla frutescens leaf extract and fractions: Polyphenol composition, antioxidant, enzymes (\u03b1-glucosidase, acetylcholinesterase, and tyrosinase) inhibitory, anticancer, and antidiabetic activities","volume":"10","author":"Wang","year":"2021","journal-title":"Foods."},{"key":"B6","doi-asserted-by":"publisher","first-page":"671","DOI":"10.3892\/etm.2014.1775","article-title":"Effects of fructus akebiae on learning and memory impairment in a scopolamine-induced animal model of dementia","volume":"8","author":"Wang","year":"2014","journal-title":"Exp Ther Med."},{"key":"B7","doi-asserted-by":"publisher","first-page":"434","DOI":"10.3390\/md17080434","article-title":"Phlorotannins from undaria pinnatifida sporophyll: extraction, antioxidant, and anti-inflammatory activities","volume":"17","author":"Dong","year":"2019","journal-title":"Mar Drugs."},{"key":"B8","doi-asserted-by":"publisher","first-page":"57","DOI":"10.1093\/aob\/mcs104","article-title":"Expression of floral mads-box genes in sinofranchetia chinensis (lardizabalaceae): implications for the nature of the nectar leaves","volume":"110","author":"Hu","year":"2012","journal-title":"Ann Bot."},{"key":"B9","doi-asserted-by":"publisher","first-page":"1037","DOI":"10.1007\/s10722-020-00885-9","article-title":"Phenotypic characterization of stauntonia obovatifoliola hayata subsp.
