Objective; To observe the affinity of several hundred native Flavones with PPARγ.Method; To dock compounds into active stock in 2PRG with DOCK software and score. Result; To 2PRG,isoflavonids have more affinity compared with flavonoid.There are only 1% below score-32 in flavonoid, but 5% in isoflavonids. Conclusion; native Flavones have determinate affinity with PPARγ-2PRG, especially isoflavonids have more.
