Dr. Duke's Phytochemical and Ethnobotanical Databases is an online database developed by James A. Duke at the USDA. The databases report species, phytochemicals, and biological activity, as well as ethnobotanical uses. [1] The current Phytochemical and Ethnobotanical databases facilitate plant, chemical, bioactivity, and ethnobotany searches.
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants.Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds.
A chemical database is a database specifically designed to store chemical information. This information is about chemical and crystal structures , spectra, reactions and syntheses, and thermophysical data.
PubChem is a database of chemical molecules and their activities against biological assays.The system is maintained by the National Center for Biotechnology Information (NCBI), a component of the National Library of Medicine, which is part of the United States National Institutes of Health (NIH).
Modern knowledge of medicinal plants is being systematised in the Medicinal Plant Transcriptomics Database, which by 2011 provided a sequence reference for the transcriptome of some thirty species. [63] Major classes of plant phytochemicals are described below, with examples of plants that contain them. [9] [55] [64] [65] [66]

Substructure search is used to retrieve from a database of chemicals those which contain the pattern of atoms and bonds specified by a user. It is implemented using a specialist type of query language and in real-world applications the search may be further constrained using logical operators on additional data held in the database.
