Overview
Tongkat Ali (Eurycoma longifolia Jack) is a flowering plant native to the rainforests of Southeast Asia. Motark sources Tongkat Ali roots through long-term grower networks in East Kalimantan, Indonesia, and Southern Thailand.
Extraction is performed in GMP-aligned facilities through hydroalcoholic and hot-water processes, with eurycomanone characterised by HPLC against a reference standard. Motark manufactures eurycomanone as both freebase and salt assays, across a range of purities, to the formulation brief.
Traditional use
Tongkat Ali root has a long history of use in traditional Southeast Asian preparations. The root is bitter and is traditionally prepared as a water decoction.
Motark's compound monograph documents the traditional context as cultural background only. No therapeutic claims are made and no dosage guidance is provided through this site — these are matters for licensed practitioners and the regulatory frameworks of the markets in which finished products are sold.
Modern research
The principal characterised constituents of Eurycoma longifolia include the quassinoid eurycomanone, related quassinoids, and a class of glycosaponins. Eurycomanone is the conventional standardisation marker; Motark manufactures both freebase and salt assays across a range of purities, characterised by HPLC against a reference standard.
Published peer-reviewed work on Eurycoma longifolia spans phytochemistry, analytical method development, and clinical pharmacokinetics. Citations available on request from the team.

Frequently asked
About Motark's Tongkat Ali extract.
What is Tongkat Ali?
- Tongkat Ali (Eurycoma longifolia Jack) is a flowering plant native to the rainforests of Southeast Asia. Motark sources Tongkat Ali roots through long-term grower networks in East Kalimantan, Indonesia, and Southern Thailand. Extraction is performed in GMP-aligned facilities through hydroalcoholic and hot-water processes, with eurycomanone characterised by HPLC against a reference standard. Motark manufactures eurycomanone as both freebase and salt assays, across a range of purities, to the formulation brief.
How is Motark's Tongkat Ali extract standardised?
- Motark's Tongkat Ali extract is standardised at the species level to a defined analytical specification, not against the common name. The release marker is Eurycomanone, quantified by HPLC at Freebase & salt assays. The wider chemotype is characterised across Eurycomanone, Total quassinoids, Glycosaponins. Each batch ships with a per-batch Certificate of Analysis referencing the method, the detection limits, and the release marker result.
Where is Motark's Tongkat Ali sourced from?
- Raw material is sourced from Indonesia · Thailand through long-term grower networks and partner farms. Motark operates a cultivation-first sourcing posture where the ingredient supports it, with cooperative-level intake records and chemotype documentation at the primary processing gate. Post-harvest processing and refinement takes place in India before export.
What plant part is used to produce the Tongkat Ali extract?
- Root. The plant-part discipline matters because the marker compound distribution varies across the plant — species-level identity and plant-part selection together determine what the extract actually contains, regardless of what the common name on the label suggests.
How does Motark verify species-level identity for Tongkat Ali?
- Tongkat Ali is supplied as Eurycoma longifolia specifically, verified by HPLC chemotype fingerprint against a reference standard for the species. The identity block on every Certificate of Analysis names the Latin binomial in full, the plant part, the country of origin, the harvest cycle, and the analytical method used to establish identity — not just the common name.
What certifications and documentation back Motark's Tongkat Ali supply?
- Motark operates under a Freebase & salt assays, GMP-aligned framework. Every batch ships with a per-batch Certificate of Analysis covering identity, marker quantification, heavy metals (ICP-MS or ICP-OES, per-element results), pesticide residues, microbial contamination, and — where relevant to the regulatory framing — speciation analysis. Method documentation is available on request.
Is Motark's Tongkat Ali extract commercially available?
- Motark's Tongkat Ali extract is in active commercial supply. It ships to a small number of wholesale counterparties from processing facilities in India, with material sourced from Indonesia · Thailand. Formulators and ingredient distributors can request a sample or a specification pack via the contact page.
