Abstract

Natural products have been the most productive source of new compounds. Hundreds of new compounds are in development. Some of them have pharmaceutical activities, particularly as anti-cancer and anti-infective agents. Until October, there are 1913 new compounds separated from natural sources in 2008. The compounds have covered a wide range of species, including alkaloids, flavones, terpenoids and so on. It is hoped that more efficient and effective compounds of natural resources will be found in the further discovery process.

Key words: New compounds, natural resources, alkaloids, flavones, terpenoids.
