Abstract

There has been worldwide interest in the role of polyphenolics in human diet due to their ability to protect against oxidative stress thereby potentially defending against a number of diseases. Pulses are known to contain antioxidants, but little is known about the antioxidants present in Australian faba beans (Vicia faba). Dried samples of three commercially grown Australian faba bean cultivars were milled into testa and seed components. The polyphenolic and HPLC profiles of methanolic extracts from both components were then investigated. Results indicated that most of the testa contained the majority of the polyphenolic substances and the HPLC profiles showed that they were mostly hydrophilic in nature. Research continues on the antioxidant and health benefits of the extracts.
