The Dictionary of Natural Products (DNP) is the only comprehensive and fully-edited database on natural products. It provides the busy scientist with fast access to chemical, physical, bibliographic, and structural data on over 139,000 natural products organized into more than 43,000 -virtually every natural product isolated and reported in the literature.
