Tongkat ali and eurycomanone

The scientific consensus is that most of the therapeutic effects of tongkat ali extract ought to be credited to the chemical component eurycomanone. [1] [2]

Eurycomanone is one of dozens of chemical components found in tongkat ali root. Most of these chemical components are similar to each other and classified as quassinoids. [3] [4]

In Malaysia, where there is very little remaining tongkat ali in forests, it has been tried in a year-long university research program to grow tongkat ali under ideal lab conditions as tissue culture plantlets, with special interests in the yield of eurycomanone.

A slight increase was noted, as summarized in the study abstract:

“… the content of eurycomanone was found to be higher in dried roots of tissue culture plantlets (120.76 ppm/mg) compared with matured root of E. longifolia (101.26 ppm/mg).”

For those not familiar with chemistry lab measurements:

ppm = parts per million

It’s a measurement like percent, as which it can easily be written:

101 ppm = 0.01 percent

100 000 – 10.1 ppm

10 000 – 1.01 ppm

1000 – 0.101 ppm

100 – 0.0101 ppm
