Cafestolis aditerpenoidmoleculepresent incoffeebeans. It is one of the compounds that may be responsible for proposed biological and pharmacological effects of coffee.[1]
Sources
[edit]A typical bean ofCoffea arabicacontains about 0.4% to 0.7% cafestol by weight.[2]Cafestol is present in highest quantity in unfiltered coffee drinks such asFrench presscoffee,Turkish coffeeorGreek coffee.Inpaper-filtered coffeedrinks such asdrip brewedcoffee, it is present in only negligible amounts, as the paper filter in drip filtered coffee retains the diterpenes.[3]
Research into biological activity
[edit]Coffee consumption has been associated with a number of effects on health and cafestol has been proposed to produce these through a number of biological actions.[4]Studies have shown that regular consumption of boiled coffee increasesserum cholesterolwhereas filtered coffee does not.[5]Cafestol may act as anagonistligandfor thenuclear receptorfarnesoid X receptorandpregnane X receptor,blocking cholesterolhomeostasis.Thus cafestol can increase cholesterol synthesis.[6]
Cafestol has also shownanticarcinogenicproperties in rats.[7]
Cafestol also has neuroprotective effects in aDrosophilafruit fly model ofParkinson's disease.[8][9]
