Analysis of the Essential Olis from Amomun kravak Pierre ex Gagnep by GC-MS
Objective: To establish the fingerprint chromatogram of Amomun kravak Pierre ex Gagnep. Methods: The composition of the essential oil was isolated by PR solvent and determined by GC-MS. Forty-two species of compounds were identified, of which the relative contents were calculated using square peaks to normalization, among which the character components were 1,8-cineole, β-pi-nene, α-pinene, p-cymene, etc. EMIC software was used and EMIC fingerprint chromatogram was established by selecting the character ion of those 10 compounds. Different extraction methods were also compared. Results: The GC-MS fingerprint chromatogram can provide qualitative information confirming compounds of the corresponding chromatographic peaks. EMIC was first used to reason the quality control of the medicine quality and it can establish the foundation for safe and effective quality control of the medicine and its product. PR solvent can easily extract the essential oil from the medicine. Conclusion: This method has the advantage of high efficiency and low cost, and the GC-MS fingerprint chromatogram provided the ascription and quality of the medicine and will play an important role in promoting the modernization of Chinese traditional medicine.
