iesandimprovingthepurityofanthocyanins.Inthisstudy,weusedstepwiseprecipitationandcolumnchromatographytopreliminarilypurifyanthocyaninsfrompurplesweetpotato.通過分步沉淀法，我們利用不同濃度的乙醇溶液對提取液進(jìn)行處理。由于花青素在不同濃度的乙醇中具有不同的溶解度，因此通過逐步增加乙醇濃度，可以有效去除提取液中的雜質(zhì)，同時保留大部分的花青素。這種方法操作簡單，成本低廉，是初步純化的常用方法。Byusingthestepwiseprecipitationmethod,wetreatedtheextractwithethanolsolutionsofdifferentconcentrations.Duetothedifferentsolubilityofanthocyaninsindifferentconcentrationsofethanol,graduallyincreasingtheethanolconcentrationcaneffectivelyremoveimpuritiesfromtheextractionsolutionwhileretainingmostoftheanthocyanins.Thismethodissimpletooperate,cost-effective,andisacommonlyusedmethodforpreliminarypurification.接下來，我們采用了柱層析法對分步沉淀法處理后的提取液進(jìn)行進(jìn)一步純化。柱層析法是利用不同物質(zhì)在固定相和流動相之間的吸附和解吸性質(zhì)差異進(jìn)行分離純化的方法。在本研究中，我們選用了硅膠、聚酰胺和C18等多種層析柱，通過優(yōu)化洗脫劑的種類和濃度，實(shí)現(xiàn)了對紫薯花青素的有效分離和純化。Next,weusedcolumnchromatographytofurtherpurifytheextractionsolutiontreatedbystepwiseprecipitationmethod.Columnchromatographyisamethodofseparationandpurificationthatutilizesthedifferencesinadsorptionanddesorptionpropertiesofdifferentsubstancesbetweenfixedandmobilephases.Inthisstudy,weusedvariouschromatographycolumnssuchassilicagel,polyamide,andC18toachieveeffectiveseparationandpurificationofpurplepotatoanthocyaninsbyoptimizingthetypeandconcentrationofeluents.初步純化后，我們通過紫外-可見光譜和高效液相色譜等方法對純化產(chǎn)物進(jìn)行了檢測。結(jié)果表明，經(jīng)過初步純化后，紫薯花青素的純度得到了顯著提高，為后續(xù)的研究和應(yīng)用提供了良好的物質(zhì)基礎(chǔ)。Afterpreliminarypurification,wedetectedthepurifiedproductthroughmethodssuchasUVvisiblespectroscopyandhigh-performanceliquidchromatography.Theresultsshowedthatafterinitialpurification,thepurityofpurplepotatoanthocyaninswassignificantlyimproved,providingagoodmaterialbasisforsubsequentresearchandapplication.需要注意的是，初步純化過程中操作條件的控制對純化效果具有重要影響。因此，在實(shí)際操作中，需要根據(jù)實(shí)際情況對操作條件進(jìn)行優(yōu)化和調(diào)整，以獲得最佳的純化效果。由于紫薯花青素的穩(wěn)定性較差，容易受到光、熱等因素的影響而降解，因此在純化過程中需要采取適當(dāng)?shù)谋Ｗo(hù)措施，避免其降解損失。Itshouldbenotedthatthecontrolofoperatingconditionsduringtheinitialpurificationprocesshasasignificantimpactonthepurificationeffect.Therefore,inpracticaloperation,itisnecessarytooptimizeandadjusttheoperatingconditionsaccordingtotheactualsituationinordertoachievethebestpurificationeffect.Duetothepoorstabilityofpurplepotatoanthocyanins,theyareeasilydegradedbyfactorssuchaslightandheat.Therefore,appropriateprotectivemeasuresneedtobetakenduringthepurificationprocesstoavoiddegradationlosses.本研究通過分步沉淀法和柱層析法對紫薯花青素進(jìn)行了初步純化，并獲得了較好的純化效果。這為紫薯花青素的進(jìn)一步研究和應(yīng)用提供了有力支持。Thisstudypreliminarilypurifiedpurplepotatoanthocyaninsthroughstepwiseprecipitationandcolumnchromatography,andachievedgoodpurificationresults.Thisprovidesstrongsupportforfurtherresearchandapplicationofpurplepotatoanthocyanins.四、實(shí)驗(yàn)方法與材料Experimentalmethodsandmaterials1紫薯：選擇新鮮、無病蟲害、成熟度適中的紫薯作為實(shí)驗(yàn)原料，以確保提取到的花青素含量高、品質(zhì)優(yōu)良。PurplePotato:Choosefresh,pestfree,andmoderatelymaturepurplepotatoesasexperimentalmaterialstoensurehighanthocyanincontentandexcellentqualityextracted.2試劑：包括乙醇、鹽酸、甲醇、丙酮等有機(jī)溶劑，以及用于初步純化的硅膠、活性炭等。所有試劑均為分析純，購自正規(guī)化學(xué)試劑供應(yīng)商。2reagents:includingorganicsolventssuchasethanol,hydrochloricacid,methanol,acetone,aswellassilicagel,activatedcarbon,etc.usedforpreliminarypurification.Allreagentsareanalyticalgradeandpurchasedfromlegitimatechemicalreagentsuppliers.3儀器：高效液相色譜儀、紫外可見分光光度計、旋轉(zhuǎn)蒸發(fā)儀、電子天平、恒溫水浴鍋、離心機(jī)等。3instruments:Highperformanceliquidchromatography,UVvisiblespectrophotometer,rotaryevaporator,electronicbalance,constanttemperaturewaterbath,centrifuge,etc.1紫薯預(yù)處理：將紫薯清洗干凈，去皮，切成薄片，然后在60℃下烘干至恒重，粉碎成粉末，備用。Purplepotatopretreatment:Cleanthepurplepotato,peelit,cutitintothinslices,andthendryitat60℃toaconstantweight.Crushitintopowderandsetitaside.2花青素提?。翰捎糜袡C(jī)溶劑提取法。將紫薯粉末與有機(jī)溶劑（如乙醇）按一定比例混合，在適宜的溫度下攪拌提取一定時間。提取結(jié)束后，離心分離得到上清液，即為花青素粗提液。Extractionofanthocyanins:Usingorganicsolventextractionmethod.Mixpurplepotatopowderwithorganicsolvents(suchasethanol)inacertainproportion,stirandextractatsuitabletemperatureforacertainperiodoftime.Afterextraction,centrifugetoobtainthesupernatant,whichisthecrudeextractofanthocyanins.3初步純化：采用硅膠柱層析和活性炭脫色相結(jié)合的方法進(jìn)行初步純化。將花青素粗提液上樣至硅膠柱，用不同比例的有機(jī)溶劑進(jìn)行洗脫，收集洗脫液。然后，將洗脫液通過活性炭脫色，去除其中的色素和其他雜質(zhì)。3Preliminarypurification:Acombinationofsilicagelcolumnchromatographyandactivatedcarbondecolorizationwasusedforpreliminarypurification.Loadthecrudeextractofanthocyaninsontoasilicagelcolumn,elutewithdifferentproportionsoforganicsolvents,andcollecttheeluent.Then,theeluentisdecolorizedwithactivatedcarbontoremovepigmentsandotherimpurities.4花青素含量測定：采用高效液相色譜法（HPLC）測定純化后的花青素含量。通過紫外可見分光光度計對花青素進(jìn)行定性分析，確定其最大吸收波長。然后，在HPLC上設(shè)置相應(yīng)的檢測波長，以標(biāo)準(zhǔn)品為對照，測定樣品中花青素的含量。Determinationofanthocyanincontent:Highperformanceliquidchromatography(HPLC)isusedtodeterminethepurifiedanthocyanincontent.QualitativeanalysisofanthocyaninswasconductedusingaUVvisiblespectrophotometertodeterminetheirmaximumabsorptionwavelength.Then,setthecorrespondingdetectionwavelengthonHPLCandmeasuretheconten
