Quality Study of Volatile Oils from Rhizoma Acori Tatarinowii

Objective To analyze the constituents of volatile oils from Rhizoma Acori Tatarinowii by gas chromatography-mass spectrometry(GC-MS) for evaluating its quality.Methods The volatile oils from 35 batches of Rhizoma Acori Tatarinowii were extracted by steam distillation.The volatile constituents were separated and identified by GC-MS,and their relative percentages were determined by area normalization.With the amount of their common components as the observation index,hierarchical clustering analysis was carried out with software SPSS 16.0.Results Thirty-eight compounds from the volatile oil had been identified,and the common constituents were borneol,alpha-terpineol,beta-caryophyllen,cis-methyl isoeugenol,trans-methyl isoeugenol,beta-asarone,and alpha-asarone.The volatile oils from 35 batches of Rhizoma Acori Tatarinowii were clustered into 6 categories.Conclusion The quality of volatile oils varies greatly in different batches of Rhizoma Acori Tatarinowii,and it is needed to further study the quality standard of Rhizoma Acori Tatarinowii.
