Studies on the chemical constituens of essential oil from the roots of Glycyrrhiza pallidiflora

OBJECTIVE To analyse the chemical constituents from the roots of Glycyrrhiza pallidiflora Max.METHODS The chemical components were obtained by steam distillation,separated and identified by GC MS and elucidated based on the standard mass spectral data respectively.The relative content of each component was calculated by area normalization.RESULTS 25 peaks were separated and all of them were identified.The main chemical components were linoleic acid ethyl ester (32.77%),hexadecanoic acid ethyl ester (10.02%),decane,2,3,7 trimethyl (6.49%),5 methyl heneicosane (5.74%),tricosane (3.80%),1 cyclohexylnonene (3.70%),eicosane (3.63%),octadecanoic acid and ethyl ester (3.59%) respectively.CONCLUSION The study was reported for the first time.The results here provided solid and scientific proof for the further development of Glycyrrhiza pallidiflora Max
