Objective: Choose Bupluerum chinense collected from songxian
henan province as the object
to study the chemical compositions and the dynamic change law of B. chinense extracts. Method: The extracts were extracted by supercritical fluid extraction (SFE)
and the composition of chemical constituents of SFE was determined by chromatography-mass spectrometry (GC-MS). Result: Fifty-nine peaks have been separated and 36 peaks of them have been identified
which accounting for 74.32%-90.45% of total extracts. The relative content of the fatty acids which extracted by SFE-CO2 was 45.10%-80.95%
the aldehydes was 1.61%-5.65%
the ketones was 0.65%-1.28%. Conclusion: The fatty acids
the ketones and the esters in B. chinense are obviously different in different harvest period. The fatty acids reached the highest relative content on December
the others reached the highest content on May. This analysis can provide a certain scientific basis for the growth and collection of B. chinense.
