Abstract:
AIM: To find the optimum extraction of volatile oil. METHOD: To extract the volatile oil by steam distillation or supercritical fluid extraction (SFE). RESULT: (1) The optimum extraction of volatile oil extracting by steam distillation is: Ligustricum Chuanxiong Hort.:Soak time 12 hrs, thin powder, extract time 3hrs, and to add water with 1∶10; Alpinia Officinarum Hance: Soak time 0 hr, thick powder, extract time 3 hrs, and to add water with 1∶10; Curcuma Wenyujin Y.H. chen C. Ling: Soak time 24hrs, mild powder, extract time 1.5hrs, and to add water with 1∶5; Notopterygium incisum Ting: Soak time 0 hr, thick powder, extract time 3 hrs, and to add water with 1∶10. (2) The best condition of volatile oil extracting by SFE is: Ligustricum Chuanxiong Hort.: 60℃, thin powder, press 25MPa, extract time 1.5hrs; Alpinia Officinarum Hance: 60℃, mild powder, press 25MPa, extract time 0.5hr; Curcuma Wenyujin Y.H. chen C. Ling: 60℃, thin powder, press 20MPa, extract time 1 hr; Notopterygium incisum Ting: 60℃, thin powder, press 25MPa, extract time 1hr. CONCLUSION: Supercritical fluid extraction (SFE) is superior to steam distillation.
