Norisoprenoids and hepatoprotective flavone glycosides from the aerial parts of Beta vulgaris var. cicla.
(+)-Dehydrovomifoliol (1), 3-hydroxy-5alpha,6alpha-epoxy-beta-ionone (2), vitexin 7-O-beta-D-glucopyranoside (3), and vitexin 2''-O-beta-D-glucopyranoside (4) were isolated as new constituents from the aerial parts of Beta vulgaris var. cicla. Compounds 3 and 4 demonstrated hepatoprotective activity with values of 65.8 and 56.1%, respectively, in primary cultured rat hepatocytes with CCl4-induced cell toxicity, compared to controls. This was comparable to that of silibinin (69.8 %) which was used as a positive control.
