英文摘要：

[Objective] The research aimed to optimize the extraction process of volatile oil from the pine needle of Pinus massoniana and analyze the constituents of volatile oil.[Method] The volatile oil was extracted from the pine needle of P.massoniana by water steam distillation method.The effects of the ratio of liquid to solid,and extracting time and soaking time on the extraction yield of volatile oil from the pine needle of P.massoniana were studied through orthogonal test.The chemical constituents of volatile oil were analyzed by gas chromatography-mass spectrometry （GC-MS）.[Result] The optimum technology for extracting the volatile oil from the pine needle of P.massoniana was as follows：the ratio of liquid to solid of 9：1,extraction time of 3 h,and soaking time of 7 h.Ninety six peaks were separated from the volatile oil from the pine needle of P.massoniana.Thirty five of them （93.13%） were identified and the main compounds were monoterpinenes,sesquiterpenes and some alcohol,ester compounds.[Conclusion] This study provided scientific basis for further comprehensive exploitation and utilization of the pine needle of P.massoniana.
