摘　　要：毛蕊杜鹃(Rhododendron tubulosum Ching ex wang wei-yei)系杜鹃花科杜鹃花属植物,分布于四川、西藏、甘肃和青海,其中青海分布最广,藏民常作为单方草药用于治疗肺炎和老年慢性气管炎,具有镇咳、祛痰作用,本文用自制的同时水汽蒸馏-溶剂萃取装置,从采自青海玉树州的毛蕊杜鹃鲜叶和嫩枝提取挥发油。The volatile oil of Rhododenudron tubulosum ching ex.. Wang wei-yei was extracted by the device of simultaneous steam distillation-solvent extraction made in our laooratory. By using capillary gas chro-matography-mass spectrometry and Kovats Index, 3G compounds constituting 71. 88% of total chro-matographic peak area, were identified. Guaiacol was separated by cooling and recrystallization and i-dentified by melting point and MS, 1R, and 1H NMR spectrometry.
