Platycladus orientalis leaves are widely used in traditional medicine to treat different ailments. In the present study, the volatile constituents were obtained by n-hexane extraction and hydrodistillation. Comprehensive metabolomic profiling was performed using GC-MS analysis. Furthermore, in vitro antioxidant potential and enzyme-inhibitory activity were assessed and supported by in silico profiling. Results revealed the predominance of monoterpene hydrocarbons in the hydrodistilled volatile oil (42.30 %) followed by oxygenated sesquiterpenes (32.10 %); with cedrol as the main component. Diterpenoids (49.70 %) and sesquiterpene hydrocarbons (13.43 %) were the major components of the n-hexane extract; with vulgarol A, a diterpene alcohol, as the major constituent. The volatile oil demonstrated significantly higher antioxidant potential across all assays, including ABTS and DDPH scavenging activity, CUPRAC, and FRAP assays. However, the n-hexane extract demonstrated broad inhibitory effects against butyrylcholinesterase, tyrosinase, α-amylase, and α-glucosidase enzymes, supported by molecular docking study and predictive ADME profiling. Therefore, it may be concluded that the n-hexane extract is a viable option for treating dysregulated enzyme conditions. In addition, the potential use of volatile oil in the pharmaceutical industries and management of oxidative stress can be inferred. These results warrant further studies to validate the therapeutic potential of the volatile oil and the n-hexane extract.
