XIA Qing-song, LU Jin-qing, LI Qiang. HS-SPME-GC-MS Analysis on Changes in Volatile Components in Raphani Semen Before and After Stir-frying[J]. Chinese journal of experimental traditional medical formulae, 2017, 23(2): 57-61. DOI: 10.13422/j.cnki.syfjx.2017020057.
Objective: To investigate the changes in chemical compositions of volatile components and their relative contents in Raphani Semen crude and stir-fried products. Method: Headspace solid phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS) analysis technique was used to analyze the volatile components in Raphani Semen crude and stir-fried products; peak area normalization method was used to calculate the relative contents of each components. Result: The 26 and 27 compounds were separated and identified from Raphani Semen crude and stir-fried products respectively
involving a total of 11 common components
respectively accounting for 80.3%and 54.90%of total volatile components. The components with higher contents in crude Raphani Semen included dimethyl disulfide (23.26%)
dimethyl trisulfide (13.74%)
erucic acid (3.45%)
and oleic acid (2.98%). The components with higher contents of stir-fried products included linolenic acid (9.43%)
oleic acid (8.80%)
palmitic acid (5.64%)
dimethyl disulfide (5.21%)
and dimethyl trisulfide (4.18%)
etc. Conclusion: HS-SPME-GC-MS technology could be used to analyze the changes in chemical compositions of volatile components and their relative contents in Raphani Semen crude and stir-fried products
lay certain theoretical foundation for explaining the material basis of efficacy differences between Raphani Semen crude and stir-fried products
and provide scientific basis for further research and comprehensive utilization.
