Objective: To analyze the chemical constituents of the volatile oils in Medinilla arboricala.
Methods: The chemical constituents was extracted from Medinilla arboricola by SPME. The components of chemical constituents of volatile oil separated and identified by GC-MS. The relative content of each component was determined by area normalization.
Results: 60 kinds of components were separated and identified, accounting about 100% of the total chemical constituents.
Conclusion: The main chemical constituents of Medinilla arboricola are D-Limonene (9.47%), [3R-(3à, 3aá,7á, 8aà]-octahydro-3,8, 8-trimethyl-6-methylene-1H-3a, 7-Metha noazulene (9.10%),3,4,5,6,7,8-hexahydro-4a, 8a-dimethyl-1 H-Naphthalen-2-one (6.15%), 1,4-Methano-1H-indene, octahydro-4-methyl-8-methylene-7-(1-methylethyl)-,[ 1S-(1à,3aá,4à,7à,7aá)] (5.58%), 1H-3a,7-Methanoazulene,2,3,4,7,8,8a-hexahydro-3,6,8,8-tetramethyl-[3R, (3à,3aá,7à,8aà)] (5.30%), 1H-3a,7-Methanoazulene,octahydro-3,8,8-trimethyl-6-methylene-[3R-(3à, 3aá,7á,8à)] (5.33%), Cyclohexene, 1-methyl-4-(5-methyl-1-methylene-4-hexenyl)-,(S)-(5.19%), Acetone (5.08%) etc.
