Abstract: The present invention relates to a preparation method of a general library and a focused library from crude extracts of natural products including herbal drugs, said libraries, and the method for developing new drugs such as an anticancer drug and new substances using said libraries. The method comprises step of attaching crude extract of natural products to the solid phase resin, and step of washing the compounds and reactants that are not attached.

Abstract: The present invention relates to a reaction vessel for organic synthesis and a block device for the reaction vessel and synthetic method of compound using thereof. More particularly, the present invention provides a solid phase synthetic reaction vessel and a block device for the reaction vessels which are capable of simultaneously synthesizing chemical libraries by combinatorial chemistry method automatically or semiautomatically.
