Quote from the lab manual:
Caffeine is present in tea leaves and in coffee to the extent of about 4%. Tea also contains two other alkaloids, theobromine and theophylline. These last two relax the smooth muscles where caffeine stimulates the heart and respiratory systems.

Both caffeine and theophylline stimulate the heart and respiratory systems and relax smooth muscle (such as in the bronchioles). Theophylline is somewhat more toxic and somewhat less powerful a CNS stimulant than caffeine, but they are more similar than different.

Tea 30-70mg
Cola 30-45mg

Guarana Magic Power (common in Germany),
15 ml alcohol with 5g Guarana Seeds        250.0 mg

Guarana capsules with 500 mg G. seeds  25.0 mg / 

capsule assuming 5% caffeine in seeds as stated in literature

Guarana soda pop is ubiquitous in Brazil and often available at tropical groceries here. It's really tasty and packs a wallop. Guarana wakes you up like crazy, but it doesn't cause coffee jitters.

It is possible that in addition to caffeine, there is some other substance in guarana that also produces an effect, since it 'feels' different than coffee. Same goes for mate
