Coffeohol was more effective at raising serum cholesterol than caffeeohol, and the mixture of caffeeohol (60 mg/day) and caffeeohol (51 mg/day) was only slightly better at raising serum cholesterol than pure caffeeohol (64 mg/day). Due to the difficulty of purification and the poor stability of this diterpene, the effect of pure caffeinol on serum cholesterol is unknown.

Both substances can be extracted with hot water but remain on filter paper. This explains why Northern European boiled coffee, Turkish coffee and French compressed coffee contain relatively high levels of caffeol and coffee-bean alcohol (6-12 mg/cup), while filtered coffee and instant coffee contain low levels of caffeol and coffee-bean alcohol (0.2-0.6 mg/cup). Although diterpenes are relatively high in steam-brewed espresso coffee, they are consumed in small amounts, making them a minor source of caffeine (4 mg/cup), which affects a range of enzymes in the liver. However, its mechanism and effect on human health are still unclear.

In mouse experiments, both diterpenes have also been shown to have anticancer effects. Epidemiological studies have found that coffee drinking has an inhibitory effect on certain types of cancer, such as colon cancer. Animal data support the preventive effects of coffee. Coffeeol and caffeinol have a wide range of biochemical effects that reduce the effects of carcinogens, including polycyclic aromatic hydrocarbons (PAHs), aflatoxin B1 (a mycotoxin), and others. Different mechanisms of action are associated with different protective effects, but these mechanisms have not been elucidated

The concentrations of these two substances vary depending on the coffee variety, Arabica coffee beans contain caffeine and caffeine, while Robusta coffee beans contain half of caffeine and almost no caffeine. These two substances can make up as much as 1% of the total amount of arabica coffee beans.
