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.
