板栗花纯露的抗氧化活性研究 Title:AntioxidantActivityofChestnutFlowerHydrosol:AResearchStudy Abstract: Inrecentyears,increasingattentionhasbeenfocusedonthepotentialhealthbenefitsofnaturalantioxidantsfoundinvariousplantsources.Inthisstudy,weaimedtoinvestigatetheantioxidantactivityofchestnutflowerhydrosol(CFH)andevaluateitspotentialasanaturalantioxidant.Thestudyemployedvariousantioxidantassays,includingtotalphenoliccontent(TPC),totalflavonoidcontent(TFC),andradicalscavengingassays.TheresultsrevealedahighantioxidantcapacityofCFH,suggestingitspotentialasanaturalantioxidant. Introduction: Oxidativestresscausedbyfreeradicalsiscloselyassociatedwiththedevelopmentofvariouschronicdiseases.Antioxidantsplayacrucialroleinneutralizingfreeradicals,therebypreventingthedamagecausedbyoxidativestress.Naturalantioxidantsderivedfromplantsourceshavegainedsignificantscientificinterestduetotheirpotentialhealthbenefits.Chestnutflowerextractpossessesvariousbioactivecompoundssuchasphenoliccompounds,flavonoids,andanthocyanins,whichhavebeenreportedtoexhibitpotentantioxidantactivity.Thus,thisstudyaimedtoinvestigatetheantioxidantactivityofCFHanditspotentialasanaturalantioxidant.
