CRC Handbook of Phytochemical Constituents of GRAS Herbs and Other Economic Plants is a unique catalog that includes more than 15, 000 phytochemical constituents from over 1, 000 higher plant species. This volume covers all of the generally-recognized-as-safe (GRAS) herbs and at least 250 important food and medicinal plants. Each entry features the scientific name, one or more common names, a listing of phytochemical constituents, a single datum or range of quantitative data (wet-weight to dry-weight in parts per million), two-letter abbreviation identifying the plant part, and three-letter abbreviation(s) indicating the source(s) of the data.
The extraordinary amount of data compiled into an easy-to-use tabular format makes the CRC Handbook of Phytochemical Constituents of GRAS Herbs and Other Economic Plants a volume useful to all pharmacologists, toxicologists, nutritionists, pharmacognicists, and food scientists.
