A typical bean of Coffea arabica contains about 0.6% cafestol by weight. Cafestol is present in highest quantity in unfiltered coffee drinks such as French press coffee or Turkish coffee/Greek coffee. In filtered coffee drinks such as drip brewed coffee, it is present in only negligible amounts.
Potential biological activity
Cafestol has also shown anticarcinogenic properties in rats. Cafestol may act as an agonist ligand for the nuclear receptor farnesoid X receptor and pregnane X receptor, blocking cholesterol homeostasis. Cafestol also has neuroprotective effects in a Drosophila fruit fly model of Parkinson's disease. Cafestol and kahweol from coffee extracts have been claimed as beneficial in the treatment of mesothelioma.
