Abstract:  Objective: To understand the protection mechanism of cinnamic acid derivatives to the damage of DNA. Methods: The protection potency of cinnamic acid derivatives to the damage of DNA in the Phen-CuSO4-VC system has been investigated at the ribodesose level with both ultraviolet spectrophotometric method and the TBA reaction, for reference to the effects of Mannitol. Results: Cinnamic acid derivatives do have the protective function to the damage of DNA caused by ·OH.

Key words: derivative of cinnamic acid, hydroxyl radicals, DNA damage
