[Analysis the chemical constituents of volatile oils in Medinilla arboricola by SPME-GC-MS].
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.


CONCLUSIONS
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.
