The plant is a rich source of essential oil and is predominantly extracted from the rhizomes. On the other hand, the leaves of the plants are usually considered as an agrowaste. The valorization of these <i>Curcuma</i> leaf wastes into essential oils is becoming accepted globally. In the present study, we aim to extract essential oils from the leaves of <i>Curcuma longa</i> (LEO), <i>C. aromatica</i> (REO), and <i>C. anguistifolia</i> (NEO). The chemical composition of these essential oils was analyzed by GC-MS. Free radical scavenging properties were evaluated against the radical sources, including DPPH, ABTS, and hydrogen peroxide.
