Abstract
Objective: To provide the foundation for reasonable utilization by analysing the essential oils from Serissa serissoides in different seasons. Method: Essential oils were obtained by steam distillation. The chemical components were separated and identified by gas chromatography-mass spectrometer(GC-MS). The relative content of each component was determined by area nomalization. Result: Forty-three peaks were identified from autumn material, representing 78.91% of the total oil. Main constituents of the essential oil from the autumn material were found to be 1b, 5, 5, 6a-tetramethyl-octahydro-1-oxa-cyclopropa [a] inden-6-one (7.32%); methyl linolenate (4.14%); cubenol (5.97%); 2-methoxy-4-vinylphenol (10.87%); δ-9(10)-tetrahydrocostunolide-1-keto (35.51%). Seventy-two peaks were identified from spring material, representing 79.88% of the totaloil. Main constituents of the essential oil from the spring material were found to be caryophyllene(3.315%); ethylbenzene(3.523%); 3-hexen-1-ol(4.537%); 2-methoxy-4-vinylphenol(6.513%); 5-propionyl-2-chlorobenzeneacetic acid, methyl ester(8.541%), germacrene D(12.311%). Conclusion: The same compounds in both materials are as follows: 2,2-dimethyl-6-methylene-cyclohexanepropanol; 2-methoxy-4-vinylphenol; 3,7-dimethyl-1,6-octadien-3-ol;cubenol;docosane and eicosane. It seems that they are the diagnostic components in these medicinal materials. Essential substances are different in quantity and quality in different seasons.
