The most authoritative answer I've found on the web is the MSDS for caffeine, which considers guaranine a synonym. Not the most reliable source, but I'll take it over any page with "Rainforest Energy" in the title.
On which topic: "The active constituent of guarana seed is not caffeine, but guaranine. The two stimulants ar similar in the laboratory, but authorities on xanthines make a clear distinction between caffeine and guaranra seed as to activity and body effects."
Before you get your hopes up and look at the page I grabbed that from - there's nothing else useful on the page.
Here's my personal favorite paragraph about just what guaranine is: "Guarana contains a crystallizable principle called guaranine. It has the same chemical composition to caffeine, theine and cocaine, and the same physiological action, along with tannic acid, catechutannic acid starch, and a greenish fixed oil."
Cocaine: C17 H21 N1 O4 Caffeine: C8 H10 N4 O2
Unless I'm totally missing something, which is always a possibility.
