Title：StudyontheSecondaryMetabolitesofEndophyticFungifromTwoIslandPlants
Introduction:
Endophyticfungiaremicroorganismsthatliveinsideplanttissues,andtheyhavebeenfoundinallplantspecies.Thesefungiplayimportantrolesinplantgrowth,development,anddefense.Moreover,endophyticfungiproduceawiderangeofbioactivesecondarymetaboliteswhichhavepotentialforuseasdrugs,pesticides,andotherapplications.Inrecentyears,thestudyofendophyticfungihasbecomeahotresearchtopicinthefieldofnaturalproductschemistry.Inthisproject,weaimtoinvestigatethesecondarymetabolitesofendophyticfungifromtwoislandplantsandexploretheirpotentialbiologicalactivities.
Objectives:
1.Isolationandidentificationofendophyticfungifromtwoislandplants;
2.Screeningandanalysisofthesecondarymetabolitesproducedbytheendophyticfungi;
3.Evaluationofthepotentialbiologicalactivitiesoftheidentifiedsecondarymetabolites.
Methods:
1.Collectionandidentificationofplantsamplesfromtwoislands;
2.Surfacesterilizationandisolationofendophyticfungifromplanttissues;
3.Identificationofendophyticfungibymorphologicalandmolecularmethods;
4.Fermentationcultureoftheendophyticfungiandextractionofsecondarymetabolites;
5.Separationandpurificationofthesecondarymetabolitesbycolumnchromatography;
6.Evaluationofthepotentialbiologicalactivitiesofthepurifiedcompounds,suchasanti-inflammatory,antioxidant,andantimicrobialactivities.
ExpectedResults:
1.Identificationofatleasttwoendophyticfungifromeachplantspecies;
2.Isolationandpurificationofseveralsecondarymetabolitesproducedbytheendophyticfungi;
3.Identificationandcharacterizationofthechemicalstructuresofthepurifiedcompounds;
4.Evaluationofthepotentialbiologicalactivities,andidentificationofsomepotentialdrugcandidates.
Conclusion:
Thisstudyisexpectedtoprovidenewinsightsintothediversityandbioactivityofendophyticfungifromislandplants,andalsooffernewsourcesofnaturalproductsforthedevelopmentofdrugsandpesticides.
