This web site collates the names and structures of naturally occurring polycyclic polyprenylated acylphloroglucinols (PPAPs). It was created by Professor Robert B. Grossman over 20+ years, and he continues to add new entries as they appear in the literature. Visit here for more information about this database. Thanks to the ACS Division of Organic Chemistry for hosting.

You can find a statistical analysis and an alphabetical listing of compounds below this table.
