ABSTRACT
AIM:
To establish a quantitative method of determining thymol and carvacrol in Shushi Ganmao Ling(dripping pill)(Herba Moslae,Herba Artemisiae Annuae,Radix Scutellariae,etc.).METHODS:
The GC method was used with HP-17 quartz capillary column(HP 50% PhMe Silicone,10 m?0.25 mm?0.25 ?m).The initial temperature of chromatographic column was at 130 ℃ for 14 min,then elevated to 220 ℃ with the rate of 20 ℃/min,and retention for 36 min.RESULTS:
The linearities of thymol and carvacrol were respective in the range of 12.51 ?g/mL-125.1 ?g/mL(r=0.999 8) and 21.52 ?g/mL~215.2 ?g/mL(r=0.999 7).The average recoveries were 97.9%(RSD was 1.69%) and 100.6%(RSD was 2.27%).RSD of repeatability were 1.88% and 1.60%,respectively.CONCLUSION:
The method is reliable,accurate and specific.It can be used for quality control of Shushi Ganmao Ling(dripping Pill).
