西青果颗粒在多种溶出条件下溶出曲线测定及溶出机制研究 Title:DeterminationofReleaseProfileandMechanismofXiqingFruitGranulesunderVariousDissolutionConditions Introduction: XiqingFruitGranulesareatypeofherbalmedicineformulatedfromacombinationofChineseherbalingredients.Thecontrolledreleaseofthesegranulesplaysavitalroleinensuringtheirefficacyandsafetyforpatients.Therefore,itisessentialtoinvestigatethereleaseprofileandmechanismofXiqingFruitGranulesundervariousdissolutionconditions.Thisstudyaimstoanalyzethedissolutionbehaviorofthesegranulesandunderstandtheunderlyingmechanismforoptimaltherapeuticoutcomes. MaterialsandMethods: 1.PreparationofXiqingFruitGranules:TheXiqingFruitGranuleswerepreparedbyfollowingthestandardextractionprotocols.Thegranuleswerethencharacterizedusingtechniquessuchasscanningelectronmicroscopy(SEM)andFourier-transforminfraredspectroscopy(FTIR)toconfirmthenatureoftheparticlesandthepresenceofactiveingredients. 2.DissolutionStudies:DissolutionstudiesofXiqingFruitGranuleswereconductedusingdifferentdissolutionconditions,includingpHvariations,temperaturechanges,anddifferentmediacompositions.Thedissolutionprofilesweremeasuredusingadissolutiontesterequippedwithappropriatemethods. 3.DataAnalysis:Thedissolutiondatawereanalyzedusingvariousmathematicalmodels,suchaszero-order,first-order,Higuchi,Korsmeyer-Peppas,andHixson-Crowellmodels.Themodelfittingdatahelpedtoidentifythereleasemechanismandkineticsofthegranulesunderdifferentdissolutionconditions.
