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 217 peaks and 100 compounds were identified, accounting for 78.3% of the total essential oil.

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
