INTRODUCTION
Plant phenolics form an extensive group of compounds, which prevent oxidation of lipids and may have beneficial effects on human health. These phenolic compounds occur naturally in plant sources such as olive oil (1),2), tea and fruits (3), rice bran (4), oat groats and hulls (5) and herbs (6). They appear to have desirable medicinal properties. Some have been reported to be anti-tumor agents and to exhibit anti-viral and antimicrobial activities (7),(8), hypotensive effects (9) and antioxidant properties (10). Recent evidence suggested that phenolics may play an important role in the regulation of plant metabolism (11). For example, flavonoids have been shown to be naturally occurring auxin transport regulators (12). In short, the plant phenolics play a major role in both plant and animal health. Although much basic research still remains to be done, it is possible that many of these compounds, either as isolates or in conjunction with other compounds, may be used in bot...See the full content of this document
