The essential oils of Juniperus are highly beneficial medicinally. The present study aimed to assess the chemodiversity and bioactivity of Juniperus formosana , Juniperus przewalskii , Juniperus convallium , Juniperus tibetica , Juniperus komarovii , and Juniperus sabina essential oils from the Qinghai-Tibet Plateau. The results revealed 92 components in six essential oils: α-pinene (2.71-17.31%), sabinene (4.91-19.83%), and sylvestrene (1.84-8.58%) were the main components. Twelve components were firstly reported in Juniperus oils, indicating that the geographical location and climatic conditions of the Qinghai-Tibet Plateau produced the unique characteristics of Juniperus essential oils. The chemodiversity of Juniperus essential oils varied greatly, with J. sabina having the most recognized components ( 64 ) and the highest chemodiversity (Shannon-Wiener index of 3.07, Simpson's diversity index of 0.91, and Pielou evenness of 0.74). According to the chemodiversity of essential oils, the six plants were decided into the α-pinene chemotype ( J. formosana ), hedycaryol chemotype ( J. przewalskii , J. komarovii , J. convallium , J. tibetica ), and sabinene chemotype ( J. sabina ). PCA, HCA and OPLS-DA showed that J. formosana and J. sabina were distantly related to other plants, which provides a chemical basis for the classification of Juniperus plants. Furthermore, bioactivity tests exhibited certain antioxidant and antibacterial effects in six Juniperus oils . And the bioactivities of J. convallium , J. tibetica , and J. komarovvii were measured for the first time, broadening the range of applications of Juniperus . Correlation analysis of components and bioactivities showed that δ-amorphene, β-udesmol, α-muurolol, and 2-nonanone performed well in the determination of antioxidant activity, and α-pinene, camphene, β-myrcene, as well as (E)-thujone, had strong inhibitory effects on pathogenic bacteria, providing a theoretical basis for further research on these components.
