Fractionations of the extract provided hexane, dichloromethane, ethyl acetate and aqueous extracts. The oil and extracts were analysed for the phytochemicals present. They were evaluated by using antibacterial susceptibility, brine-shrimp lethality and antioxidant capacity assays. &lt;strong&gt;Results:&lt;/strong&gt; All together 49 compounds (accounting 93.66%) were identified in the litsea oil by GC-MS. Monoterpenes being dominant components, the oil constituted 15.96% of citral (geranial and neral). Other major constituents were capric acid (12.44%), β-caryophyllene oxide (7.69%), linalool (5.96%), eucalyptol (5.13%) and cis- β-terpineol (4.22%). Litsea oil, hexane extract and dichloromethane extract displayed very effective antibacterial property. Ethyl acetate extract (LC&lt;sub&gt;50&lt;/sub&gt; = 21.52 μg mL‒1) and litsea oil (LC&lt;sub&gt;50&lt;/sub&gt; = 31.62 μg mL‒1) were found highly cytotoxic against brine-shrimp nauplii. Ethyl acetate (IC&lt;sub&gt;50&lt;/sub&gt; = 124.57 μg mL‒1) and dichloromethane (IC&lt;sub&gt;50&lt;/sub&gt; = 271.08 μg mL‒1) extracts displayed a modest DPPH free radical scavenging activity. &lt;strong&gt;Conclusion:&lt;/strong&gt; Phytoconstituents present in the &lt;em&gt;L. cubeba&lt;/em&gt; fruits from Nepal were analysed. Litsea oil and the extracts have displayed high antibacterial and potentially anticarcinogenic activities.&lt;/p&gt;
