Abstract:
Objective:To analyze and compare the volatile oil in the leaves of Juniperus formosana Hayata from Yuzhong and Lu-qu. Methods:The volatile oil from Juniperus formosana Hayata was extracted by steam distillation, and then identified by gas chroma-tography-mass spectrometry ( GC-MS) . Results:The average yield of the volatile oil from the leaves of Juniperus formosana Hayata from Yuzhong and Lugu was 0. 21% and 1. 45%(w/w), respectively. Between the two areas of the volatile oil from the leaves of Juniperas formsana, totally 40 peaks were separated from the volatile oil from Gansu with 38 ones (95%) were identified. Totally 51 peaks were separated from the volatile oil from Xizang with 47 ones (92%) were identified. The maln constituents in the former volatile oil wereα-pinene(44.92%),l-caryophyllene(9.23%),( -)-isoledene(6. 50%),a-caryophyllene(5.60%),myrcene(4.54%) and d-cadinene(3. 37%), and those in the latter were di-epi-cedrene(31. 87%),cyclohexene(15. 28%),γ-elemene(10. 05%), lanceol (5. 80%) and α-pinene(5. 79%). Conclusion:The constituents in the volatile oil in the leaves of Juniperus formosana Hayata from the two different regions are various, and the differences in the yield and compounds are notable. The method provides reference for the establishment of quality standard for Juniperus. formosana Hayata.
