Study on the Chemical Constituents of Volatile Oil from Different Parts of Embelia parviflora Wall. ex A. DC by GC-MS

[Objective]To study the chemical constituents of volatile oil from different parts of Embelia parviflora Wall. ex A. DC. [Method]The volatile oil was respectively extracted from the root,stem and leaf of E. parviflora by steam distillation and then analyzed by gas chromatography-mass spectrometry ( GC-MS) . The relative content of all isolated compounds was determined by area normalization. [Result]Eleven chemical constituents were identified from the root of E. parviflora,accounting for 77.67% of total volatile oil. Thirty six chemical constituents were identified from the stem,accounting for 92.88%of total volatile oil. Seventy four chemical constituents were identified from the leaves,accounting for 85.11% of total volatile oil. [Conclusion]The study result was accurate and reliable,which could provide scientific basis for the establishment of quality standard, further development and utilization of E. parviflora.
