Abstract
The orthogonal test and the supercritical carbon dioxide fluid extraction were used for optimizing the extraction of the essential oil from Plumeria rubra var. actifolia for the first time. Compared with the steam distillation,the optimal operation parameter of extraction was as follows:extraction pressure 25 MPa,extraction temperature 45 ℃ ;separator Ⅰ pressure 12 MPa,separator Ⅰ temperature 55 ℃; separator Ⅱ pressure 6 MPa, separator Ⅱ temperature 30 ℃. Under this condition the yield of the essential oil was 5. 8927％.The components were separated and identified by GC-MS. 53 components of Plumeria rubra var. actifolia measured by SFE method were identified and determined by normalization method. The main components were 1,6,10-dodecatrien-3-ol,3,7,11-trimethyl, benzoic acid, 2 -hydroxy-, phenylmethyl ester, 1,2 -benzenediearboxylic acid, bis ( 2-methylpropyl ) ester, etc.. 1,2-Benzenedicarboxylic acid,bis (2-methylpropyl)este. took up 66. 11％ of the total amount, and there was much difference of the results from SD method.关键词
