C13 norisoprenoids from Brassica fruticulosa.
Five C13 norisoprenoids, one of them glucosilated, have been isolated from the leaves of Brassica fruticulosa (Brassicaceae). The structure (3S,4R,7E,9S)-3,4,9-trihydroxy-5,7-megastigmadiene, has been assigned to the new compound. All the structures have been determined by spectroscopic means and chemical correlations.
