Abstract
Purpose: To extract and analyze the volatile components of Chrysanthemum morifolium Ramat. 'huaiju' by headspace solid-phase microextraction (HS-SPME) and gas chromatography–mass spectrometry (GC–MS). Methods: Volatile components were extracted by HS-SPME and identified by GC–MS. The relative contents of the components were determined by area normalization. Results: The enhanced SPME conditions of C. morifolium involved sample extraction using a 65 μm polydimethylsiloxane/divinylbenzene extraction fiber after balancing for 40 min at 80 °C. A total of 48 components of the essential oil were identified. The major constituents are 2,6,6-trimethylbicyclo[3.1.1]hept-2-en-4-ol, acetate (15.90 %), 4,6,6-trimethyl-bicyclo[3.1.1]hept-3-en-2-one (14.86 %), 2,7,7-trimethyl-bicyclo[3.1.1]hept-2-en-6-one (13.08 %), and cyclohexene,3-(1,5-dimethyl-4-hexenyl)-6- methylene (5.97 %). Conclusion: HS-SPME and GC–MS are convenient, rapid, and reliable approaches for analyzing the volatile components of C. morifolium. Keywords: Chrysanthemum morifolium Ramat., Headspace Solid-phase Microextraction, Gas Chromatography–Mass Spectrometry, Volatile component
Highlights
Chrysanthemum morifolium Ramat. is a traditional Chinese medicinal herb that belongs to the Compositae family
The present study aims to analyze volatile components from C. morifolium (Huaiju) by headspace solid-phase microextraction (HS-SPME) and gas chromatography–mass spectrometry (GC–mass spectrometry (MS))
A previous study compared SPME/gas chromatography (GC)– MS with the conventional steam distillation extraction (SDE) method followed by GC/MS to identify volatile compounds in C. morifolium
Summary
Chrysanthemum morifolium Ramat. is a traditional Chinese medicinal herb that belongs to the Compositae family. The present study aims to analyze volatile components from C. morifolium (Huaiju) by HS-SPME and GC–MS. By Associate Professor Mingxing Zhi (Henan Institute of Science and Technology, China). Following HS extraction, SPME fibers were injected into the GC apparatus and maintained in the GC inlet for 3 min.
