Results & Discussion
  In these 5 Asteraceae Grown in Taiwan, we used hot water to extract for two hours to mimic Chinise herbs' decoction. Then we freezed dry such extracts and took them to antioxidant assays in vitro.
   In fig 1, 2, 3, 4, and 5, we extremely surprised to found that these 5
Asteraceaes Grown in Taiwan have savenging effects as better as catachin, a well-known antioxidant of plants' purified compound, before we purified their compositions. In fact, this appearance has much commercial use because we have no need to purify them and we can use them in medicine directly.
  We have proved that
5 Asteraceaes Grown in Taiwan have the ability to inhibit ROS. But we still unknown what is the real situation in vivo. In advance, we hope to use living organisms to prove these herbs' efficiency.
