Abstract:
AIM: To Study the chemical constituents of volatile oil in Herminium bulleyi(Rolfe) Tang et Wang,ethnic drug from Miao Nationality. METHODS: The volatile oil of Herminium bulleyi was extracted by CO_2-supercritical fluid extraction method and steam distillation method,and their chemical constituents were analyzed and identified by GC-MS. RESULTS: SFE-CO_2 extraction gained 32 known constituents and steam distillation 33 ones.Volatile oil yield by SFE-CO_2 was three times that by steam distillation. CONCLUSION: The effect of SFE-CO_2 extraction on yield of volatile oil has obvious benefits both easy and quick.Cetylic acid content in volatile oil by SFE-CO_2 extraction is as high as 52%.
