ABSTRACT Eurycoma longifolia Jack, commonly known as Tongkat Ali, is a medicinal herb traditionally valued for its aphrodisiac properties, with eurycomanone being principal bioactive quassinoid. This study introduces novel, cost‐effective method the sensitive detection of using nitrogen‐doped carbon quantum dots (N‐CQDs) fluorescent probe. The spectral characteristics probe were carefully analyzed UV–vis and fluorescence spectrophotometric techniques, sensing mechanism was investigated through Stern–Volmer thermodynamic studies, revealing static quenching interaction. A Box–Behnken design experiment applied to optimize conditions including pH, incubation time, concentration, ensuring high sensitivity robustness. reduced quadratic model found significant ( p value > 0.0001) pH N‐CQDs concentration most influential factors. rigorously validated following ICH guidelines displaying excellent linearity in range 0.25–6.0 μg/mL, (LOD 0.067 μg/mL), accuracy precision (RSD < 1.5%). proposed technique successfully analysis real Ali samples, demonstrating practical utility herbal analysis. results showed good agreement reported chromatographic methods, positioning promising alternative conventional analytical methods.
