Abstract

Abstract: 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, 3Gcompounds 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, IR, and ¹H NMR spectrometry.

Key words: Rhododendron tubulosum citing ex. Wang wei-yei, Volatile oil, Chemical constituents, Guaiacol
