Objective: Optimization and to establish the heat better oral liquid from best autumn lee alcohol
ketone of patchouli
thymol
sweet fineleaf schizonepeta herb phenol of capillary gas chromatography determination conditions. Method: The chromatographic column:HP-5 (0.25 μm×0.32 mm×30 m)elastic quartz capillary column;injection port temperature 220℃
FID detector temperature 220℃
temperature programmed
starting temperature 110℃
keep for 10 min
at 25℃ to 230℃
temperature programmed to keep 9.2 min
diversion ratio 10:1
including 1 L sample quantity. Result: The autumn lee alcohol
ketone of patchouli
thymol
sweet fineleaf schizonepeta herb phenol concentration in sample quantity is 1.109-0.110 9
0.504-0.050 4
0.987-0.098 7
0.605-0.060 5 g·L-1 and good linear relationship between peak area
linear relationship is Y=1 653.05X-1.46(r=0.999 8)
Y=1 207.45X-16.10(r=0.999 7)
Y=1 691.68X-18.06(r=0.999 5)
Y=1 547.18X+5.55(r=0.999 6)
sample recovery rate was 99.9%-103.7%(n=9)
98.4%-104.4%
104.4%-101.4% and 101.4%-97.2%
RSD was 1.9%
2.3%
2.5% and 1.9% respectively. Conclusion: The optimized method has good separating degree
