I think I found more than one citation for you today.
Embedded within the article by Paul Stamets "Portobello and Crimini
inventions are paying off, so watch for Blanco Bellos" in Mushroom,
The Jounral of Wild Mushrooming, Issue 72, Vol. 19, No. 3, Summer
2001, p 5. This article is based on "...chapter 21, "Growth Parameters
of the Portobello Mushroom" from Growing Gourmet and medicinal
Mushrooms. Specifically, it speaks of hydrazines in Abaricus
brunnescens (crimini) and notes under "Medicinal Properties" the
"This mushroom contains compounds that inhibit the enzyme aromatase.
Aromatase is associated with tumor growth. Compounds inhibiting
aromatase have potential for th treatment or prevention of breast
cancer. (Bankhead, 1999). A diet of mushrooms for mice with implanted
tumors showed a decrease in aromatase as mushroom consumption
increased. However, this report is in contradiction to other studies."
There is also a section on "Hydrazines, and one in particular:
Agaritine". You may already have access to "Growing Gourmet and
Medicinal Mushrooms". If not it is available from Stamets company,
Fungi Perfecti, which is on-line.
