The essential oil from guarana [Paullinia cupana H.B.K. var. sorbilis (Mart.) Ducke] was analysed. Nine components were identified, namely (2) methylbenzenes, (1) cyclic monoterpene and (2) cyclic sesquiterpene hydrocarbons, (2) methoxyphenylpropenes and (2) alkylphenol derivatives. The alleged psychoactivity of the essential oil is presumably due to the identified constituents estragole and anethole. Any contribution of aminated metabolites of estragole/anethole to the alleged psychoactivity…

It is suggested that complexes containing caffeine and catechins (and their dimers) might be responsible for anti-platelet aggregatory activity in guarana seeds and might offer health benefits towards decreasing risk of thrombosis and cardiovascular disease.
This review involves a general description of Guarana, including its chemical and pharmacological properties as well as its production, consumption and economical importance. The revision covers the

An aqueous extract of guaraná (Paullinia cupana) decreases platelet thromboxane synthesis.
The effects of an aqueous extract of guaraná on rabbit platelet aggregation and thromboxane synthesis were examined and could be responsible, at least in part, for the antiaggregatory action of Guaraná.

Traditional forms of guaraná agriculture practised by the Saterê-Mawé Indians compare favourably with the plantation system favoured by government agronomists, and Indigenous techniques of hand-processing guaranán are shown to produce better quality in the finished product than those practices adopted by industrial concerns.

Evidence for the biogenic formation of amphetamine derivatives from components of nutmeg.
The similarity of their chemical structure to that of mescaline or certain amphetamine derivatives has led to the assumption that myristicin and elemicin are phenylallyl derivatives present in nutmeg.
