ABSTRACT
Objective:
To establish a GC method for the imultaneous determination of cinnamaldehyde, bornyl acetate, costunol-ide,dehydrocostus lactone,magnolol and honokiol in Dutong pills.Methods:
The determination was performed on an HP-5 column (30 m ×0.32 mm,0.25 μm) with programmed temperature. The carrier gas was nitrogen with the flow rate of 2.0 ml·min-1. The injection volumn was 1 μl and the sample split ratio was 51. The inlet temperature was 280 ℃. The detector was a flame ionization detector with temperature at 300 ℃.Results:
The linear ranges were 32.28-516.40 μg·ml-1for cinnamaldehyde(r=0.999 3), 27.06-433.00 μg·ml-1for bornyl acetate(r=0.999 2),25.65-410.40 μg·ml-1for costunolide(r=0.999 3),26.10-417.60 μg ·ml-1for dehydrocostus lactone(r=0.999 3),24.01-384.20 μg·ml-1for magnolol(r=0.999 0) and 18.32-293.10 μg·ml-1 for honokiol(r=0.999 4). The average recovery was 99.71%(RSD=0.67%),99.34%(RSD=1.18%),100.16%(RSD=0. 34%),100.40%(RSD=0.39%),99.32%(RSD=1.22%) and 99.58%(RSD=0.58%)(n=6),respectively.Conclusion:
The method is simple,sensitive and accurate,can be used to supplement the insufficient quality control of Dutong pills.
