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.
