摘要: 首次利用不同固相萃取纤维(SPME)结合GS-MS分析水线草挥发油成分。利用SPME共检测出化合物83个,其中PA检测出45个,PDMS-DVB检测出51个,100 μm PDMS检测出20个,三者同时检测到邻苯二甲酸二丁脂、2,6,10,14-四甲基-十七烷、十七烷、十六烷,6,10,14-三甲基-2-十五烷酮五种成分;PA和PDMS-DVB共同检测化合物21个,PDMS与PDMS/DVB、PA共同检测的化合物分别为7个和9个。研究结果为利用SPME-GS/MS检测水线草挥发油成分提供了试验依据。

Abstract: The analysis of volatile components extracted from Hedyotis corymbosa (L.) Lam. using different solid phase microextraction fibers (SPME-fibers) coupled with GC-MS was reported for the first time. All 83 compounds identied by SPME-GC/MS includes 45 compounds for fiber PA, 51 compounds for fiber PDMS-DVB, 20 compounds for fiber PDMS. In term of chemicals, Pentadecane, 2,6,10,14-tetramethyl, Heptadecane, Dibutyl phthalate, Hexadecane, 2-Pentadecanone 6,10,14trimethyl could be tested by the three fibers, the numbers of common compounds of PA/PDMS-DVB, PDMS-DVB/PDMS and PA/PDMS were 21, 9 and 7 separately. The results show SPME-GS/MS can be applied to analysis of aromatic compounds in Hedyotis corymbosa.
