Effect of Jiangxi Characteristic Processing Technology on Volatile Components of Cimicifugae Rhizoma
To analyze the effect of honey bran stir-frying method in Zhang faction and honey chaff stir-frying method in Jianchang faction on the composition and relative content of volatile components in Cimicifugae Rhizoma.
Method:
2
The volatile oil in different processed products of Cimicifugae Rhizoma was extracted by steam distillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The inlet temperature was 260 ℃
the transmission line temperature was 250 ℃
the carrier gas was helium
the flow rate was 1.0 mL·min
-1
the split ratio was 10∶1
the injection volume was 1 μL. The column temperature was set at 70 ℃ by programmed heating
rising to 150 ℃ by 2 ℃·min
-1
and keeping it there for 2 min
rising to 240 ℃ by 6 ℃·min
-1
and keeping it there for 3 min
rising to 300 ℃ by 25 ℃·min
-1
and keeping it there for 2 min. The relative content of each component in volatile oil was calculated by peak area normalization method.
Result:
2
A total of 73 components were identified from raw products of Cimicifugae Rhizoma
37 components were identified from honey bran stir-frying products
93 components were identified from honey chaff stir-frying products
and 71 components were identified from honey stir-frying products. The relative content of
n
-hexadecanoic acid was the highest among all components in different processed products
accounting for 30.38%-46.47%of the total volatile components. In addition to fatty acids
volatile oils also contained alkanes
esters
alcohols
etc. There were 8 common components with relative content ≥1.0% in raw and processed products of Cimicifugae Rhizoma
after stir-frying with honey bran
the relative contents of these 8 components showed an upward trend
but showed a decreasing trend after stir-frying with honey chaff.
Conclusion:
2
After processing with Zhang faction method or Jianchang faction method
the composition and relative content of volatile components in Cimicifugae Rhizoma were significantly changed. This study can provide a scientific basis for explaining the processing mechanism of Jiangxi characteristic Cimicifugae Rhizoma decoction pieces.
