Book excerpt: Database of Biologically Active Phytochemicals and Their Activities presents an alphabetical tabulation of some 3,000 biologically active phytochemicals (elements and compounds) from higher plants. The data includes at least one and in some cases as many as 25 biological activities for each phytochemical. The database also provides data on effective dose, inhibitory concentrations, and lethal and/or toxic doses. Entries after 1990 indicate the source of the data. Database of Biologically Active Phytochemicals and Their Activities makes it possible to locate the concentration of many compounds in plants and compare this data with dosage information to calculate how much of a given plant food it would take to cause lethality, antioxidant activity, hypoglycemic activity, or artemicidal activity. Using WordPerfect (TM) 5.1's search function, you can find compounds by entering a key word in their name (e.g., choline or salicyl-), locate all compounds with a given activity (e.g., hypotensive), or list all compounds for which ED50 data is entered or reported.
