Isolierung und Charakterisierung der Hauptcarotinoide aus Blütenblättern von Brassica napus

Abstract

From the yellow petals of rape (Brassica napus) five major carotenoids have been isolated. Based on UV/NIS, CD, 400-MHz ¹H-NMR, and mass spectra, they were identified as (9'Z)-neoxanthin, (all-E)- and (9Z)-violaxanthin, and (8'R)- and (8'S)-luteoxanthin.
