Title: GC-MS Analysis of Volatile Oil from Hedyotis lancea
Abstract: Objective:To study the chemical constituents of volatile oil from Hedyotis lancea.Method: Two kinds of volatile oil were separately prepared by steam distillation(SD) and supercritical CO2 extraction(SFE).The constituents were separated and analyzed by gas chromatography-mass spectrometry with the area normalization method to determine the relative percentage content of each component.Result: Sixty-seven compounds were isolated and 32 compounds were identified by SD that composed about 73.76% of the total essential oil;and 82 compounds were isolated and 45 compounds were identified by SFE that composed about 61.62% of the total essential oil.Conclusion: The principal chemical constituents of the volatile oil from H.lancea are aliphatic derivatives,aromatic derivatives and terpene derivatives.There are some differences in the principal chemical constituents and content of the volatile oil extracted by SD and SFE.
