Abstract
Gas chromatography-mass spectrometry combined with solid-phase microextraction (SPME-GC-MS) was used for the determination of volatile compounds of longan arillus, epicarpium and seeds.
Twenty-nine peaks in arillus were separated and completed by mass spectrometry.
The principal components were bicyclo[4.4.0]dec-2-ene-4-ol,2-methyl-9-(prop-1-en-3-ol-2-yl)-(41.69%); 1H- cycloprop[e]azulene,1a,2,3,4,4a,5,6,7b-octahydro-1,1,4,7-tetramethyl-,[1aR-1aα,4α,4aβ,7bα)]-(3.16%); Tricyclo[3.3.0.0(2,8)]octan-3-one,7-hydroxy-4-methyl-4-(propan- 2-on-1-yl)-(1.91%) and diethyl Phthalate (1.05%). Thirty compounds were measured in seeds.
The main components were 1H-cycloprop[e]azulene, 1a,2,3,4,4a,5,6,7b- octahydro-1,1,4,7-tetramethyl-,[1aR-(1aα,4α,4aβ,7bα)]-(30.38%); caryophyllene (18. 04%); azulene,1,2,3,4,5,6,7,8-octahydro-1,4-dimethyl-7-(1-methylethenyl)-,[1S-(1α, 4α,7α)]-(5.21%); 3-nonyne(5.15%),benzene,(cyclohexyloxy)(4.92%); naphthalene, 1,2,3,5,6,7,8,8a-octahydro-1,8a-dimethyl-7-(1-methylethenyl)-,[1R-(1α,7β,8aα)]-(3.79%) and 3-carene(3.13%). Twenty-five compounds were identified in epicarpium.
The main components were gitoxigenin (47.59%); Xanthumin (22.92%); columbin (7.76%); benzene,1,1′-[3-(3-cyclopentylpropyl)-1,5-pentanediyl]bis-(6.21%) and resibufogenin (3.39%).
Twenty-nine peaks in arillus were separated and completed by mass spectrometry.
The principal components were bicyclo[4.4.0]dec-2-ene-4-ol,2-methyl-9-(prop-1-en-3-ol-2-yl)-(41.69%); 1H- cycloprop[e]azulene,1a,2,3,4,4a,5,6,7b-octahydro-1,1,4,7-tetramethyl-,[1aR-1aα,4α,4aβ,7bα)]-(3.16%); Tricyclo[3.3.0.0(2,8)]octan-3-one,7-hydroxy-4-methyl-4-(propan- 2-on-1-yl)-(1.91%) and diethyl Phthalate (1.05%).
