Abstract: Plant polyphenols, which are widely present in plants, have many functions beneficial to human health. However, the actual molecular interactions mechanism of polyphenols with biological systems remains mostly unclear. This paper reviews on some mechanisms that have been identified, includes: ①non specific mechanism, such as antioxidation action and interactions with membranes; ②specific mechanism, such as interactions with enzymes,transcription factors and receptors. Besides, this paper introduces some others mechanisms, such as inhibiting the digestion and absorption of triglyceride; playing as a promoting factors of growth and proliferation for beneficial gut bacteria beneficial gut bacterias growth. The better knowledge on biological effects of polyphenols interactions with cell components will contribute to develop nutritional and pharmacological strategies oriented to prevent and cure human diseases.
