What are the active ingredients of tongkat ali

Version 1,0, September 2009
I understand that in recent months, a Malaysian producer of tongkat ali extract has heavily promoted their product with claims of a scientific standardization.
As if this were of scientific relevance, they stated that their product is composed of 40% glycosaponins, 22% eurypeptides and 30% polysaccharides.
Judging from the wide circulation of their product, it seems to be easy indeed to fool people by using scientific-sounding terms.
The active components of tongkat ali (Eurycoma longifolia Jack) have of course been scientifically established.
There is an excellent, impartial, not product-oriented scientific source on the Internet:

You can read a printscreen of the relevant section of the above-mentioned page here:
ICS UNIDO Medicinal and Aromatic Plants
You can debunk yourself the pseudoscience of ”40% glycosaponins, 22% eurypeptides and 30% polysaccharides”.
To start with, do the following:
On your browser, load the page:
http://www.ics.trieste.it/MAPs/MedicinalPlants_Plant.aspx?id=613
Using Internet Explorer, click Edit / Find and run a search for the following terms, one by one: glycosaponins, saponins, eurypeptides, peptides, polysaccharide.
Only the term ”polysaccharide” is found on the page, listing the active components of Eurycoma longifolia Jack (tongkat ali), but NOT as an active chemical
