Codonopsis lanceolata GC-MS Optimization of extraction Qualitative analysis SFE-CO2

摘要

Objective: To extract and analyze the chemical components of volatile oil from Codonopsis lanceolata. Methods: Supercritical CO2 fluid extraction procedure was used as the extraction method and its process was optimized. The volatile oil was separated by GC-MS and determined by normalization method. Results: The best conditions were temperature 40℃, pressure 20 MPa, and extraction time 3 h. The yield of volatile oil was 1.21%. Forty-six volatile compounds were identified from the volatile oil o...更多

Objective: To extract and analyze the chemical components of volatile oil from Codonopsis lanceolata. Methods: Supercritical CO2 fluid extraction procedure was used as the extraction method and its process was optimized. The volatile oil was separated by GC-MS and determined by normalization method. Results: The best conditions were temperature 40℃, pressure 20 MPa, and extraction time 3 h. The yield of volatile oil was 1.21%. Forty-six volatile compounds were identified from the volatile oil of Codonopsis lanceolata. The main compounds of volatile oil were stigmasta, [7, 22-dien-3-ol, ] accounting for 15.71%, 1, 4-dimethyl-8-isopropylidenetricyclo [5.3.0.0 ] decane for 13.64%, trans-squalene for 12.12%, 9, 12-octadecadienoic acid methyl ester for 11.45%, and stigmast-7-en-3-ol, for 10.52%. These components accounted for 63.44% of the total volatile oil from Codonopsis lanceolata. Conclusion: The optimized SFE-CO2 method coupled with GC/MS is efficient. This may be a good method for further comprehensive development and utilization of Codonopsis lanceolata.收起
