Content Determination of 7 Volatile Components in Nvjin Pill by GC
Objective: To develop a method for simultaneous content determination of cinnamaldehyde
bornyl acetate
paeonol
myristicin
furanodienone
ligustilide and α-cyperone in Nvjin pill. Method: The quantitative analysis was carried out on a capillary column of HP-5(250 μm×30 m
0.25 μm)
temperature programming:initial temperature 50℃
keeping 1 minute
heating up to 130℃ with a rate of 20℃·min-1
keeping 10 minutes
and then heating up to 180℃ with a rate of 2℃·min-1
keeping 1 minute
inlet port temperature 230℃
detector temperature 250℃
split sampling at a split ratio 10:1. Result: The 7 components were completely separated and can be well separated from other components. Cinnamaldehyde
bornyl acetate
paeonol
myristicin
furanodienone
ligustilide and α-cyperone showed a good linear relationship with the chromatographic peak area within the range of 0.013 4-1.342 3
0.003 4-0.343 0
0.023 0-2.302 7
0.017 3-1.728 5
0.030 1-3.008 5
0.017 2-1.724 8
0.003 1-0.308 8 μg respectively. The average recoveries (n=6) were 99.6%
99.4%
99.3%
99.1%
99.8%
99.3% and 99.0%
respectively
with relative standard deviations (RSD) of 0.4%
0.4%
0.3%
0.2%
0.1%
0.4%
0.5%
respectively (n=6). Conclusion: This method is simple
accurate
reproducible and convenient for the quality control over Nvjin pill.
