HYDRODISTILLATION AND VOLATILE COMPOUNDS IDENTIFIED FROM DRIED POWDER JASMINE (JasminumsambacL.) BY GC-MS

Jasmine (JasminumsambacL.) is one of scented Thai flower have been used for Thai traditional medicine. It has therapeutic properties and can be used as a cardiotonic agent, antidizziness, antidepressant, anti-inflammatory and antiseptic. In the present study, hydrodistillation, the most common method was exploited to extract volatile oil from jasmine dried powder. Theyield of the extracts was 0.05% v/w. Chemical composition of the volatile oil were analysed by GC-MS, a process that integrated the features of gas chromatography and mass spectrometry to improve efficacy of volatile oil analysis. Volatile oil is complex mixture, constituted by terpenoid hydrocarbons, oxygenated terpenes. It was found that the main constituents of the volatile oil was (E,E)-7,11,15-Trimethyl-3-methylene-hexadeca-1,6,10,14-tetraene.Low yield of the jasmine volatile oils can be improved in future study by considered sample preparation and extraction process. GC-MS is selective, rapid and efficient for both the identification volatile oil components and composition variations.
