摘要
One of the most promising approaches to overcome the cur- rent limits of new drug development is to utilize natural prod- ucts with known empirical efficacy, i.e., reverse pharmacol- ogy [ 1,2]. Natural product-based drugs can be classified into two categories, natural product-derived compounds （NPC） and natural product extracts （NPE）. NPC means pure com- pounds derived from natural products. Aspirin from willow trees and Taxol from pacific yew trees are famous examples of the NPC drugs.
