The essential oils of Cinnamomum griffithii and C. macrocarpum were analyzed by GC and GC–MS and evaluated for their antioxidant and anticholinesterase activities. The essential oils of leaf and bark of C. griffithii were characterized by the presence of 30 components, with methyl eugenol (38.5–43.8%) as the major component. A total of 11 components were characterized in the leaf and bark of C. macrocarpum essential oil with the most abundant component was safrole (54.5–59.5%). The bark oil of C. griffithii demonstrated significant activity on DPPH (IC50 73.4 μg/mL) and a high phenolic content (192.0%), while the leaf oil inhibited oxidation of β-carotene/linoleic acid with an inhibition value of 65.5 μg/mL. Acetylcholinesterase and butyrylcholinesterase inhibition were assessed and the results showed that C. macrocarpum bark oil exhibited significant activity with inhibition values of 55.8% and 66.1%, respectively at a concentration of 1 mg/mL.
