          摘   要  目的  建立一种测定化橘红药材中展青霉素含量的方法。方法  采用高效液相色谱-串联三重四极杆质谱联用(HPLC-
          MS/MS)法。化橘红样品粉末加水溶散后经果胶酶酶解,用乙腈高速匀浆提取,提取液依次经无水硫酸镁-无水醋酸钠(4∶1,m/m)
          混合粉末分散固相萃取和SHIMSEN 228型固相净化柱净化后,采用岛津Shim-pack XR-ODS色谱柱、水-乙腈流动相、电喷雾离子
          源、负离子扫描、多反应监测模式测定,以基质标准曲线校正、外标法定量。结果  展青霉素的检测质量浓度在5~200 ng/mL范围
          内与峰面积成良好的线性关系(r=0.999 6);精密度、重复性、稳定性(12 h)试验的RSD均小于6%;低、中、高3种浓度加样量的平
          均加样回收率分别为83.90%、92.08%、92.21%(RSD分别为11.09%、5.53%、1.75%);定量限为6 μg/kg,检出限为3 μg/kg。20批样
          品均未检出展青霉素。结论  所建方法可实现对化橘红中展青霉素的快速筛查和准确定量,可为化橘红的安全性研究和质量控制
          提供实验依据和方法。

          ABSTRACT    OBJECTIVE  To  establish  a  method  for  the  content  determination  of  patulin  in  Citri  Grandis  Exocarpium.
          METHODS  High-performance  liquid  chromatography-triple  quadrupole  mass  spectrometer(HPLC-MS/MS)was  used  for  the
          analysis.  After  water-soluble  dispersion  and  pectinase  enzymolysis,  the  Citri  Grandis  Exocarpium  sample  was  extracted  by
          acetonitrile with high-speed homogenated. The extracted solution was conducted dispersive solid phase extraction by mixing powder
          of  MgSO4  and  NaAC (4∶1,m/m),then  purified  on  SHIMSEN  228  solid  phase  purification  column. Water  acetonitrile  was  used  as
          mobile phase, and the Shim-pack XR-ODS column was used to separate the target compound. And it was detected by electrospray
          ionization  in  the  negative  mode  under  multiple  reaction  monitoring,  and  quantified  by  the  external  standard  method  with  matrix-
          matched  standard  correction  curves.  RESULTS  Patulin  showed  good  linear  correlation  in  the  concentration  from  5  to  200  ng/mL
         (r=0.999 6). RSDs of precision, reproducibility and stability tests (12 h) were all lower than 6%. The average recoveries at low,
          medium, high concentrations were 83.9%, 92.08%, 92.21%, respectively (RSDs were 11.09%, 5.53%, 1.75%, respectively). The
          limit  of  quantitation  was  6  μg/kg  and  limit  of  detection  was  3  μg/kg.  Patulin  was  not  detected  in  20  batches  of  samples.
          CONCLUSIONS  Established  method  can  be  used  for  the  rapid  detection  and  accurate  quantification  of  patulin  in  Citri  Grandis
          Exocarpium, which can provide experimental basis and method for safety study and quality control of Citri Grandis Exocarpium.
