Effects of 60Co Irradiation with Different Doses on the Volatile Components in Huodan Pill / 中国药房

ABSTRACT

OBJECTIVE:To establish a method for the contents determination of volatile components in Huodan pill and study the effects of 60Co irradiation with different doses on the volatile components in Huodan pill. METHODS:GC-MS was used to de-termine the contents of patchouli alcohol and the ralative contents of β-patchouliene,α-guaiacene,seychellesene,α-patchouliene,α-bulnesene,5,11-diene guaiacyl,and unidentified objects in Huodan pill after 60Co irradiation with different doses. Column was HP-5MS by programmed temperature,volume temperature was 250℃,split ratio was 50:1,detector was triple quadrupole mass spectrometer detector,MS1 quadrupole temperature was 150℃,MS2 was 150℃,carrier gas was helium,flow rate of column was 1.2 ml/min,and the volume injection was 1 μl;ion source was EI,bombarding energy was 70 eV,temperature of ion source was 230℃,temperature of transmission line was 280℃ and scan range was 50-500 amu. RESULTS:The linear range of patchouli alcohol was 0.103 1-2.062 0μg(r=0.999 4);RSDs of precision,reproducibility and stability tests were lower than 1.0%;recovery was 98.05%-102.32%(RSD=1.8%,n=9). 60Co irradiation with different doses had little effects on the 8 volatile components in Huodan pill. CONCLUSIONS:60Co irradiation can be used for sterilization on Huodan pill,but irradiation dose should be controlled. The method is simple,good reproducibility,and can be used for the contents determination of volatile components in Huodan pill.
