GC/MS-TOF ANALYSIS OF ESSENTIAL OIL COMPOSITION OF THE Allium schoenoprasum L. BULBS CULTIVATED FROM QUANG TRI - VIETNAM

Abstract

The research content of the study was an investigation of the chemical compositions from the essential oils of Allium schoenprasum L. bulbs collected from Quang Tri-Vietnam. The essential oils extracted by hydrodistillation method. The chemical components of essential oils were analyzed using of gas chromatography-time-of-flight mass spectrometry (GC/MS-TOF). The results show that the main ingredient of the oil is organic sulfur compounds, especially, allyl polysulfides, which account for more than 76% of substances identified. The results also show that solvents used to dissolve the essential oil affect the results of the analysis. Organic sulfur compounds are best soluble in n-hexane. Comparative analysis indicated that GC/MS-TOF could analyze more compound than GC/MS-Quadrupole.
