AB  - Singlet oxygen (1O2) produced by illuminated photosensitizer Rose Bengal was 
      detected by its bleaching effect on N,N-dimethylnitrosoaniline(DMNA). The 1O2 
      could be scavenged by green tea extracts (GTE), with the scavenging action being 
      obvious at the early stage of photosensitized oxidation. The higher the 
      concentration of GTE in the photooxidation reaction system, the stronger the 1O2 
      scavenging action. The scavenging effect of the fresh GTE solution on singlet 
      oxygen was better than that of old solution. The preventive effects of GTE on 
      lipid peroxidation induced by 1O2 in ghosts and microsomal membranes were also 
      observed. Malondialdehyde (MDA) production was found to be completely inhibited 
      by a high concentration of GTE in the reaction system.
