"Can a Tree Help Me Pee? Pygeum and BPH"
by Dr. Robert Q. Thompson, Professor of Chemistry and
Biochemistry, Oberlin College

Benign prostatic hyperplasia (BPH) or enlarged prostate afflicts
a majority of men in the United States over the age of sixty. Some men have serious enough symptoms (e.g. difficulty urinating) to be seen by a doctor, and some of those will resort to over-the-counter botanicals rather than prescribed pharmaceuticals. One of these botanicals is pygeum, the ground up bark and/or extract of the bark of an African cherry tree, Prunus africana. Pygeum contains a number of compounds that may be effective in treating BPH.

An analytical method was developed and optimized to identify and quantify five BPH-active compounds in bark and pygeum capsules. The method involved saponification of natural esters in the material, liquid-liquid and liquid-solid extraction, and LC-APCI-MS (triple quadrupole) quantification. Four bark samples and seven commercial products were analyzed, and the concentrations of the BPH-active compounds were compared.

Please RSVP for the dinner September
13th by emailing to Dr. Chris Boyd ( At the event, we can take credit card payments, checks made out to “Cleveland ACS”, or cash. The cost is $20 for members and guests, $10 for retirees or unemployed, and $5 for students.
