Gas Chromatographic-Mass Spectrometric Analysis of Essential Oil of Jasminum officinale L var Grandiflorum Flower

Purpose : To analyze the essential oil composition of the flower of Jasminum officinale L. var. grandifloroum L. ( Jasminum grandiflorum ) by gas chromatography-mass spectrometry (GC-MS). Methods : The optimum GC-MS conditions used for the analysis were 250 o C inlet temperature, 150 o C MSD detector temperature, and GC oven temperature program as follows: 100 o C initial temperature, increased to 270 o C at 4 o C/min, final temperature 270 o C and held for 7.5 min. Results : Thirty compounds were identified, representing 99.28 % of the oil content. The major volatile components of the flower were 3,7,11,15- tetramethyl-2-hexadecen-1-ol（phytol） (25.77 %), 3,7,11- trimethyldodeca -1,6,10-trien-3-ol (12.54 %) and 3,7,11,15- tetramethyl -1-Hexadecen-3-ol (12.42 %). Conclusion : The results show that phytol is the major volatile component of Jasminum grandiflorum . Keywords : Jasminum grandiflorum , Essential oil, Gas chromatography-mass spectrometry
