(\n                    <jats:italic>J. tibetica<\/jats:italic>\n                    ) to assess their potential for further production development. Correlations between chemical composition and the biological activities of essential oils (EOs) and ethanol (EtOH) extracts of\n                    <jats:italic>J. tibetica<\/jats:italic>\n                    were evaluated. GC\u2010MS analysis identified 74 compounds in\n                    <jats:italic>J. tibetica<\/jats:italic>\n                    needles EOs, with populations YS01 and YS04 exhibiting the highest number of constituents (70 components). Variations were observed among 17 populations in terms of total phenolic content (ranging from 4.49 to 6.69\u00a0mmol equiv. GAE\/g) and total flavonoid content (ranging from 2.43 to 3.44\u00a0mmol equiv. QUE\/g). The contents of medicinally valuable compounds, namely quercitrin and amentoflavone, also varied considerably. Population BM06 showed the highest quercitrin content (4.39\u00a0mg\/g dry weight), whereas population BM07 exhibited the highest amentoflavone content (3.53\u00a0mg\/g dry weight). Variations in antioxidant activities (DPPH, ABTS, and FRAP) and antibacterial activities were observed among the populations, with population BM03 displaying the highest antioxidant and antibacterial capacities. Based on an exploratory PLS model, compounds tentatively associated with antioxidant activity included \u03b1\u2010pinene, abietadiene, hedycaryol, \u03b3\u2010elemene, \u03b2\u2010eudesmol, and \u03b3\u2010terpinene. Those correlated with antibacterial activity included abietal, epi\u2010\u03b1\u2010muurulol, palustral, \u03b3\u2010elemene, and \u03b1\u2010pinene.
