Abstract:
OBJECTIVE:To establish a method for the content determination of menthanol in Qinagli pipa syrup. METHODS:Headspace GC was performed on the column of HP-INNOWax capillary column,column temperature was 80 ℃,temperature inlet sample was 150 ℃,the detector was hydrogen flame ionization detector with temperature of 250 ℃,the flow rate of nitrogen was 0.8 ml/min with constant flow and no split,the volume injection was 1 ml,the equilibrium temperature of headspace bottle was 80 ℃,and the equilibrium time was 20 min. RESULTS:The linear range of menthanol was 2.486-24.86 μg/ml(r=0.9999),RS-Ds of precision,stability and reproducibility tests were lower than 2%,recovery was 95.4%-99.8%(RSD=1.5%,n=9). CON-CLUSIONS:The method is simple and accurate,and can be used for the content determination of menthanol in Qinagli pipa syrup.
