The screening of antioxidant, content of total phenolics,
total flavonoid and GST inhibitory activities was
performed on various extracts of Areca catechu. Methanol
extracts of A. catechu, especially the seeds extracts, have
considerable activities compared with the other parts of
A. catechu. Further research should be followed to isolate
and identify the active ingredients with strong
antioxidationability in A. catechu.
