Title:SynergisticUltrasound-AssistedExtractionofTotalFlavonoidsfromGinkgobilobaLeafandTheirAntioxidantActivity
Abstract:
Naturalproducts,suchasflavonoids,havegainedsignificantattentionduetotheirpotentialhealthbenefits,includingantioxidantactivity.Thisstudyaimedtoinvestigatethesynergisticeffectofsurfactantsandultrasound-assistedextraction(UAE)ontheextractionoftotalflavonoidsfromGinkgobilobaleafandevaluatetheirantioxidantactivity.TheresultsdemonstratedthatthecombinationofsurfactantswithUAEenhancedtheextractionefficiencyandantioxidantactivityoftheextractedflavonoids.Thisstudyprovidesvaluableinsightsintothedevelopmentofnovelextractiontechniquesfornaturalproductsusingsurfactantsandultrasound.
1.Introduction:
Flavonoidsareaclassofsecondarymetaboliteswidelyfoundinplantspecies.Theypossessnumerousbiologicalactivities,includingantioxidant,anti-inflammatory,andanticancerproperties.Ginkgobiloba,atraditionalChinesemedicine,isrichinflavonoidsandhasbeenusedforcenturiesduetoitspotentialhealthbenefits.However,theefficientextractionofflavonoidsfromGinkgobilobaleavesremainsachallenge.
2.LiteratureReview:
Previousstudieshaveexploredvariousextractionmethodsforflavonoids,includingsolventextraction,microwave-assistedextraction,andultrasound-assistedextraction.Amongthesetechniques,ultrasound-assistedextractionhasgainedattentionduetoitsabilitytoenhanceextractionefficiency,reduceextractiontime,andpreservethebioactivecomponentsofplantmaterials.Surfactants,suchasnonionic,anionic,andcationicsurfactants,havebeenreportedtoimprovethesolubilityandextractionefficiencyoftargetcompounds.
