摘要

目的：分析比较不同固相萃取纤维头（PA，PDMS，PDMS-DVB）对白花蛇舌草挥发性成分的吸附性，并与传统的水蒸气蒸馏联用GS-MS（SD-GS-MS）方法进行比较。方法：采用PA，PDMS-DVB，PDMS 3种不同类型的固相微萃取纤维头以及水蒸气蒸馏法提取，联用GS-MS进行挥发性成分测定。结果：其中PA检测出50个成分，PDMS-DVB检测出51个，PDMS检测出18个。水蒸气蒸馏法检测出41个成分，与SPME法对比结果显示，相似度最高的为PA，共有成分为21个，其次为PDMS-DVB 15个，PDMS 6个；有16个成分未在SPME法中检出。结论：HS-SPME-GS-MS方法可简便、高效地检测白花蛇舌草挥发性成分，但不能完全替代传统的水蒸气蒸馏联用GS-MS方法。

Abstract

Objective: To analyze and compare the headspace solid-phase microextraction methods (PA

PDMS

and PDMS-DVB) on adsorption property of volatile compounds in the dried whole plants of Hedyotis diffusa

and then compare them with traditional steam and distillation coupling with gas chromatography-mass spectrometry (SD-GC-MS). Method: Three types of SPME fibers including PDMS

PDMS-DVB and PA as well as steam distillation method were used for extraction

and GS-MS was combined for determination of the contents of volatile compounds. Result: The 50 compounds were identified by using PA method; 51 compounds were identified by using PDMS-DVB; 18 compounds were identified by using PDMS; and 41 components were identified by using SD-GC-MS. As compared with SPME method

PA method had the highest similarity

with 21 common components; followed by PDMS-DVB (15 common components) and PDMS (6 common components); 16 components were not identified by SPME method. Conclusion: HP-SPME-GC-MS is a simple

rapid and effective method for detecting the volatile components in H. diffusa

but cannot completely take the place of SD-GC-MS method.
