Natural Products Alert

NAPRALERT is now offering limited free searches of the database, as well as advancing several levels of fee-based services to the natural product community, including the employment of query structures that users of our former website will be familiar with. The new NAPRALERT platform accommodates two query levels.
  • Free (with limitations) searching of the NAPRALERT database
    Includes: Organism, Pharmacology, Compound and Author-based queries.
  • Fee-based searches, charged by number of citations generated.
From time to time we will announce additional search parameters and other information on NAPRALERT. NAPRALERT exists only through user fees and tax-free contributions by those interested in seeing the database be expanded and continued. Please e-mail NAPRALERT staff for further information ( Complex searches can be carried out by NAPRALERT staff. Please e-mail NAPRALERT staff for more information.

NAPRALERTĀ® is a relational database of all natural products, including ethnomedical information, pharmacological/biochemical information of extracts of organisms in vitro, in situ, in vivo, in humans (case reports, non-clinical trials) and clinical studies. Similar information is available for secondary metabolites from natural sources.

To date more than 200,000 scientific papers and reviews are included in NAPRALERT, representing organisms from all countries of the world, including marine organisms. About 25% of the database is derived from abstracts and 75% from original articles.

We believe that our coverage of the literature is comprehensive from at least 1975 through and including 2003. Due to budget problems we only include ca. 15% of the literature from 2004 to the present, but articles are being collected and we hope to be up-to-date eventually. For additional background information, please see the About NAPRALERT page.

Please view the free sample NAPRALERT reports page to get a better idea of which data are output and how.

Our coverage of the literature in the following areas is quite comprehensive:
  • Clinical studies of natural products (including safety)
  • Natural products that affect sugar metabolism
  • Natural products that affect mammalian reproduction
  • Extracts and compounds that affect cancer growth
  • Natural products and antiviral (including HIV/AIDS) activity
  • Natural products and antitubercular activity
  • Natural products and tropical diseases
  • Ethnomedical information on more than 20,000 species of plants
  • Metabolism and pharmacokinetics
  • Natural products that affect plant growth
  • Review articles on organisms at the genus and/or species levels and reviews of secondary metabolites (Citations only)
  • Chemoprevention with natural products
  • Natural insecticides
  • Antiinflammatory activity of natural products
  • Analgesic activity of natural products
  • Plant growth stimulators and inhibitors
Note: After 2001 we discontinued data entry of essential oil articles, antibiotics from Actinomycetes, animal products (mainly insect pheromones) and fatty acid analyses
