Sinalbin ist ein SenfΓΆlglycosid, das unter anderem im WeiΓen Senf enthalten ist. Es handelt sich dabei um das Salz von Glucosinalbin mit Sinapin.cite-ref-roempp-1-2[1] Sinapin ist wiederum ein Ester der SinapinsΓ€ure mit Cholin.

Vorkommen
Eigenschaften
Aus dem Kation des Sinalbins, Glucosinalbin, wird durch Einwirkung des Enzyms Myrosinase, das in der Zelle der Pflanze an anderer Stelle gespeichert ist, unter Abspaltung der Glucose das SenfΓΆl 4-Hydroxybenzylisothiocyanat freigesetzt.cite-ref-5[5]cite-ref-6[6] Dieses erzeugt den typisch scharfen Geschmack des Senfs.cite-ref-7[7]
Nachweis
Die wichtigsten Inhaltsstoffe des WeiΓen Senfs kΓΆnnen durch Einsatz der HochleistungsflΓΌssigkeitschromatographie in Kopplung mit der Massenspektrometrie qualitativ und quantitativ nachgewiesen werden.cite-ref-8[8]
