CHAPTER ONE
1.0 INTRODUCTION
Polyphenols are natural organic chemicals characterized by the presence of large number of phenol structural units (Quideauet al., 2011). The most research-informed and chemistry-aware definition of polyphenol is termed the White–Bate-Smith–Swain– Haslam (WBSSH) definition (Haslam and Cai, 1994) which describes the polyphenol as moderately water-soluble compounds, with molecular weight of 500–4000 Dalton,having more than 12 phenolic hydroxyl groups and with 5–7 aromatic rings per 1000 Da.The number and characteristics of the phenol structures underlie the unique physical, chemical, and biological properties of a particular member of the polyphenol class(Quideau et al., 2011).
