Analysis of Chemical Composition of Volatile Oil from Rape Flowers by GC-MS

doi:10.7506/spkx1002-6630-201120032

Abstract

Abstract: Objective: To determine the chemical components in the volatile oil from rape flowers. Methods: The volatile oil in rape flowers was extracted by steam distillation method, and its chemical components were qualified and quantified by gas chromatography-mass spectrometry (GC-MS). Results: Totally 30 components were found, including 21 identified ones, accounting for 97.40% of total peak area. The major compounds were n-tetracontane (38.14%), n-tetratetracontane (30.24%), allyl isothiocyanate (10.94%), 3-butenyl isothiocyanate (9.56%), β-caryophyllene (1.02%), limonene (1.01%), and allyl thiocyanate (0.75%).

Key words: rape flower, volatile oil, steam distillation, gas chromatography-mass spectrometry (GC-MS)
