          摘  要  目的  优化石胡荽醇提物制备工艺,并考察其不同萃取部位的抗炎活性。方法  采用单因素实验和响应面法,以石胡荽总
          三萜提取率为评价指标,考察乙醇体积分数、提取时间、料液比、提取次数4个因素对总三萜醇提物加热回流提取工艺的影响,优
          化最佳工艺,并进行验证实验。以地塞米松为阳性对照药物,比较石胡荽不同萃取部位(石油醚部位、乙酸乙酯部位、正丁醇部位、
          水部位)对脂多糖诱导小鼠单核巨噬细胞RAW 264.7一氧化氮(NO)生成的影响并计算其半数抑制浓度(IC50)。结果  石胡荽总
          三萜醇提物的最优提取工艺为乙醇体积分数 70%、料液比 1∶40(g/mL)、提取时间2.0 h、提取次数3次。3次验证实验表明,石胡
          荽总三萜的平均提取率为1.134%,与预测值的相对误差为0.02%。石胡荽的石油醚部位、乙酸乙酯部位可不同程度地降低由脂多
          糖诱导的RAW 264.7细胞的NO生成,其对NO生成的IC50分别为2.44、2.22 μg/mL,均低于阳性对照药物地塞米松(7.65 μg/mL)。
          结论  优化后的石胡荽醇提物的制备工艺稳定可行,其石油醚部位、乙酸乙酯部位具有较好的抗炎活性。

          ABSTRACT   OBJECTIVE  To  optimize  the  preparation  technology  of  ethanol  extracts  from  Centipeda  minima,  and  investigate
          the  anti-inflammatory  activities  of  different  extraction  sites.  METHODS  Single  factor  test  and  response  surface  methodology  were
          adopted to investigate the effects of ethanol volume fraction, extraction time, solid-liquid ratio and extraction times on the heating
          reflux  extraction  technology  of  total  triterpenoids  ethanol  extract  using  the  extraction  rate  of  total  triterpenoids  of  C.  minima  as
          indexes,  optimize  the  extraction  technology  and  carry  out  validation.  Using  dexamethasone  as  positive  control  drug,  the  effects  of
          different  extraction  sites  of  C.  minima (petroleum  ether  part,  ethyl  acetate  part,  n-butanol  part,  water  part)  on  nitric  oxide (NO)
          production  in  mononuclear  macrophage  RAW  264.7  cells  of  mice  induced  by  lipopolysaccharide (LPS)  were  compared;  the  half
          inhibitory  concentration (IC50 )  was  calculated.  RESULTS  The  optimal  extraction  technology  of  total  triterpenoids  ethanol  extracts
          of  C.  minima  was  as  follows:  ethanol  volume  fraction  of  70%,  solid-liquid  ratio  of  1∶40 (g/mL),  extraction  time  of  2.0  h  and
          extraction  times  of  3  times.  The  3  times  of  validation  tests  showed  that  average  extraction  rate  of  total  triterpenoids  of  C.  minima
          was  1.134%,  relative  error  of  which  with  the  predicted  value  was  0.02%.  The  petroleum  ether  part  and  ethyl  acetate  part  of  C.
          minima could inhibit the generation of NO in RAW 264.7 cells induced by lipopolysaccharide to different degrees. IC50 values of NO
          production  were  2.44  μg/mL  and  2.22  μg/mL,  respectively,  and  both  of  them  were  lower  than  those  of  positive  control  drug
          dexamethasone (7.65  μg/mL).  CONCLUSIONS  The  optimized  preparation  process  of  ethanol  extracts  from  C.  minima  is  stability
          and feasibility. The petroleum ether part and ethyl acetate part have obvious anti-inflammatory effects.
