Essential oils obtained from Juniperus rigida Sieb. et Zucc. are potential natural sources for perfume and health products, and are considered as natural antimicrobial agents. This study used chromatographic fingerprint analysis and quantitative ecological methods to research essential oil composition diversity and the antibacterial activity and key soil factors affecting the synthesis of essential oils in J. rigida, which were from the different elevations in Helan Mountain (the arid hinterland) and Changbai Mountain (the humid region). Statistical results showed that the essential oil compounds of J. rigida in Helan Mountain were classified into 3 groups: germacrene D (2063 m, 2280 m, and 2340 m), β-caryophyllene (1568 m, 1883 m, and 2112 m), and α-pinene chemotype (1741 m, 1801 m, and 2182 m). While in Changbai Mountain, they can be classified into 2 major groups, the α-pinene chemotype (838 m and 1203 m) and the sylvestrene/β-myrcene chemotype (885 m, 1073 m, and 1170 m). The essential oils in middle-high elevations (2112−2280 m) in Helan Mountain were of higher yields, composition, chemical composition diversity, and antibacterial activity than low elevations. The essential oils of J. rigida needles in middle-high elevations (1073−1203 m) in Changbai Mountain had lower diversity chemical compositions but better antibacterial activity. The antibacterial activity was closely related to terpenoids in essential oils of J. rigida. Middle-high elevations in Helan and Changbai Mountains provided an excellent source of cosmetics, perfume, and industrial product development from J. rigida. Phosphorus and potassium fertilizers and water conditions should be considered first in the management of cultivation J. rigida. This study researched suitable elevations and cultivation management of J. rigida for the improvement of quality and biological activity of essential oil especially in the arid hinterland and gave insights into resource utilization, perfume and fragrance product development.

从僵尸杜鹃中获得的香精油。et Zucc。是香水和保健品的潜在天然来源，被认为是天然抗菌剂。本研究中使用指纹图谱分析和定量生态学方法继续查询精油组合物的多样性和抗菌活性，影响精油在合成关键土壤因子J.杜松，这是从在贺兰山（干旱腹地）的不同的高度和长白山（湿润地区）。统计结果表明，僵硬的香精油化合物贺兰山的三大类分为三类：germ骨D（2063 m，2280 m和2340 m），β-石竹烯（1568 m，1883 m和2112 m）和α-pine烯化学型（1741 m，1801 m，和2182 m）。在长白山中，它们可分为2大类，α-pine烯化学型（838 m和1203 m）和西维烯/β-月桂烯化学型（885 m，1073 m和1170 m）。与低海拔相比，贺兰山中高海拔（2112-2280 m）的精油具有更高的产量，组成，化学成分多样性和抗菌活性。僵硬J.的精油长白山中高海拔地区（1073−1203 m）的针叶具有较低的化学组成，但具有较好的抗菌活性。抗菌活性密切相关的精油萜类化合物J.蒿。贺兰山和长白山的中高海拔为僵硬刺槐提供了极好的化妆品，香水和工业产品开发资源。在栽培硬J的管理中应首先考虑磷和钾肥及水的条件。本研究研究了僵硬刺槐的适宜海拔和栽培管理 为提高精油的质量和生物活性，特别是在干旱的腹地，并提供了对资源利用，香水和香水产品开发的见解。
