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.展开更多

Chang, providing scientific basis for quality control. Methods The total essential oil was extracted by water-steam distillation and separated by capillary gas chromatography (GC). The components were determined by normalization method, and identified by GC-MS. Results GC-MS exhibited 242 peaks and 83 compounds were identified, accounting for 75.77% of the total essential oil. Conclusion In the total essential oil of the rhizome and root of N. incisum, monoterpenes and sesquiterpenes accounted for 13.63% and 67.93%, respectively, in which ( 1S)-β-pinene ( 1.67% ), 3-carene ( 1.05% ), limonene ( 1.22% ), and 1S-endo-bornyl acetate ( 1.68% ) as the monoterpenes and its derivatives, and ( + ) -β-elemene (6.78%), sativene (1.54%), α-caryophyllene (2.64%), germacrene D (1.67%), eudesma-4 ( 14 ), ll-diene (2.36%), α-selinene (2.42%), δ-cadinene ( 1.55% ), 3,7,11-trimethyl-2,6,10-dodecatrien-1-ol (1.03%), ( + )-elemol (5.18%), (-)-spathulenol (1.40%), guaiol (3.81%), dehydroxy-isocalamendiol ( 1.06% ), γ-eudesmol ( 1.05% ), α-eudesmol (7.97%), bulnesol (3.09%), and carotol (2. 30% ) as the sesquiterpenes and its derivatives were main components. In addition, isopropyl transcinnamate was the maximum compound ( 11.3% ) of the total essential oil.展开更多
