Studies on volatile constituents in White Tea by two ex traction methods |
| |
| Abstract: | The volatile oils of white tea were extracted by the solid phase microextraction method and the distil-lation extraction method.The components were separated by gas chromatography and identified by mass-spec-trometry respectively.35 chemical components were identified by the solid phase microextraction method and gas chromatography-massspectrometry(GC-MS)method,of them the main constituents are benzaldehyde(5.91%), phenylethyl alcohol(5.46%)and 1,6-Octadien-3-ol,3,7-dimethyl(9.02%).39 chemical components were i-dentified by the distillation extraction method and gas chromatography-massspectrometry(GC-MS)method,of them the main constituents are benzyl alcohol(5.56%),phenylethyl alcohol(8.22%)and 1,6-Octadien-3-ol, 3,7-dimethyl(5.69%) . |
