Ecophysiology of Carpobrotus rossii in Tasmania: Linking plant’s antioxidant pctivity with a natural habitat

Abstract

Flavonoids extracted from Carpobrotus rossii possess cardioprotective activity and as such there is interest in maximising the per plant yield of these compounds. This field study was undertaken to determine the environmental variables driving flavonoid production. Results suggest that production of tannin and flavonoid metabolites is not controlled by a single variable alone, but through an interplay of variables linked to oxidative stress in the plant.
