摘要
Aim To analyse the constituents of the essential oils extracted from the buds of Tussilago farfara L. in the GAP Bases of Traditional Chinese Medical Materials and provide scientific basis for quality control. Methods The essential oils were extracted by water-steam distillation and separated by GC capillary column chromatography. The components were quantitatively determined by normalization, and identified by GC-MS. Results GC-MS exhibited 259 peaks and 65 compounds were identified, accounting for 84.62% of the total essential oil. Conclusion In the total essential oil contained in the buds of Tussilago farfara L., copaene (2.36%), ( + ) -Epi-bicyclosesquiphellandrene ( 3.91% ), γ- elemene (2.18%), fl-bisabolene ( 13.93% ), spathulenol ( 3.44% ) as the sesquiterpenes and its derivatives, and 1-undecene (4.83%), ( E)-cycloundecene (8.49%), bicycle [ 10. 1.0] tridec-l-ene ( 1. 45% ), 1-tridecene (3.44%), (Z)-7,11-dimethyl-3-methylene-1,6,10-dodecatriene (2.66%), 1- pentadecene (4.57%), [ 1R-( 1R^*, 4Z, 9S^* ) ]-4,11,11-trimethyl-8-methylene-bicyclo [ 7.2.0] undec-4-ene ( 1.03% ), 6,6-dimethyl-2-methylene-7-( 3-oxobutylidene )-oxepan-3-ylmethyl acetic acid ester (2.02%), 1, E-11, Z-13-heptadecatriene ( 3.72% ), ( Z, Z, Z) -9,12,15-octadecatrien-l-ol ( 1.85% ), 3,7,11-trimethyl-dodeca-2,4,6,10-tetraenal ( 1.31% ), n-hexadecanoic acid ( 3.12% ) , (Z, Z) -9,12-octadecadienoic acid (2.26%), ( Z, Z, Z) -9,12,15-octadecatrienoic acid methyl ester ( 1.12% ) , heneicosane ( 1.82% ), and pentacosane ( 1.03% ) are the main components.
