Study on Stability of Volatile Oil in Foeniculi Fructus and Screening Its Antioxidants in Accelerated Oxidation Environment
To screen the accelerated oxidation environment with the most drastic changes in the volatile oil composition of Foeniculi Fructus
and to optimize the type and concentration of antioxidants.
Method:
2
The volatile oil of Foeniculi Fructus was extracted by steam distillation. Taking thiobarbituric acid reactive substances (TBARS) value and peroxide value (POV) as evaluation indexes
response surface method was used to investigate the effects of temperature
concentrations of ferrous ion (Fe
2+
) and azoamidine initiator V50 (AAPH) on volatile oil components of Foeniculi Fructus and its oxidation products. TBARS and POV were detected by ultraviolet chromatography. The oxidative environment with the most drastic changes of volatile oil composition of Foeniculi Fructus was screened. The type and concentration of antioxidants were selected by single factor experiments. The change discipline of volatile oil in Foeniculi Fructus after added different concentrations of antioxidants were analyzed by GC-MS.
Result:
2
The worst oxidizing environment for volatile oil of Foeniculi Fructus was as follows: temperature at 42.5 ℃
AAPH concentration of 1 g·L
-1
Fe
2+
concentration of 20.85 mg·L
-1
. Ascorbyl palmitate with concentrations of 0.2 mol·L
-1
and 0.8 mol·L
-1
could effectively improve the stability of volatile oil from Foeniculi Fructus.
Conclusion:
2
Under the accelerated oxidation environment
the terpenes in volatile oil from Foeniculi Fructus are significantly changed
but its stability can be improved by ascorbyl palmitate.
