Vorkommen
Astragalin ist ein sekundΓ€rer Pflanzenstoff, der in vielen verschiedenen Pflanzen vorkommt,cite-ref-2[2]cite-ref-3[3]cite-ref-books-wy3ybqaaqbaj-684-4-0[4] beispielsweise in Tragant (synonym Astragalus sp.), Rosa agrestis,cite-ref-pmid-25637445-5-0[5] Aristolochia indica,cite-ref-6[6]cite-ref-7[7] Cuscuta chinensis,cite-ref-8[8] der amerikanischen Kermesbeere, Hopfenextrakt,cite-ref-books-85kibwaaqbaj-400-9-0[9] Goldrutenkraut,cite-ref-books-85kibwaaqbaj-400-9-1[9] HolunderblΓΌten,cite-ref-books-85kibwaaqbaj-400-9-2[9] LindenblΓΌten,cite-ref-books-85kibwaaqbaj-400-9-3[9] ArnikablΓΌten,cite-ref-books-85kibwaaqbaj-400-9-4[9] Wein und Weintrauben,cite-ref-books-5irnbqaaqbaj-119-10-0[10] Teecite-ref-books-5irnbqaaqbaj-119-10-1[10] sowie Heidelbeeren.
Eigenschaften
Astragalin kommt nicht in Tieren vor. Es besitzt als experimenteller Wirkstoff in Zellkulturen von SΓ€ugetierzellen antioxidative und antientzΓΌndliche Eigenschaften.cite-ref-pmid-25069610-11-0[11] Es hemmt die AktivitΓ€t von Interleukin-1Ξ², dadurch wird in Folge die von NFΞΊB gemindert und der MAPK-Signalweg gehemmt.cite-ref-pmid-25637445-5-1[5] Weiterhin hemmt es die Genexpression von Cox-2 und iNOS.cite-ref-pmid-25637445-5-2[5] Es hemmt die Apoptose in Lungenepithelzellen durch Hemmung der Genexpression von Eotaxin-1 und des MAPK-Signalwegs.cite-ref-pmid-25069610-11-1[11] Astragalin-Heptaacetat fΓΌhrt dagegen in Zellkulturen von Lungenepithel zu verstΓ€rkter Apoptose, die durch Gabe des Antioxidans Acetylcystein wieder aufgehoben wird.cite-ref-12[12] Astragalin ist ein 3-O-Glucosid von Kaempferol.
