          摘   要  目的  提取补骨脂的有效成分并评价其治疗白癜风的药效。方法  利用超高效液相色谱法测定补骨脂提取液中补骨脂
          素、异补骨脂素、新补骨脂异黄酮、补骨脂异黄酮、补骨脂定、补骨脂乙素和补骨脂酚的浓度。在层次分析法和Plackett-Burman实
          验设计基础上,以上述7种成分浓度为评价指标,药材粉碎度、乙醇体积分数、浸渍时间为考察因素,采用Box-Behnken响应面法优
          化补骨脂的提取工艺并验证。将斑马鱼分为空白对照组、阳性对照组(8-甲氧基补骨脂素,10.8 μg/mL)和补骨脂提取液低、中、高
          浓度组(500、1 000、2 000 μg/mL),每组6条,通过密度测定研究补骨脂提取液对斑马鱼黑色素生成的影响。结果  补骨脂提取的
          最优工艺为药物粉碎度60目,用80%乙醇浸渍72 h;3次验证实验综合评分的平均值为98.27,RSD为1.36%,与拟合方程预测值
         (97.28)的相对误差为 1.02%。与空白对照组比较,补骨脂提取液低、中、高浓度组斑马鱼的黑色素沉着均显著增加(P<0.01)。
          结论  优化所得的补骨脂提取工艺合理可行,所得补骨脂提取液能显著促进斑马鱼黑色素的生成。

          ABSTRACT    OBJECTIVE  To  extract  the  effective  components  of  Psoralea  corylifolia  and  evaluate  its  efficacy  in  the  treatment
          of  vitiligo.  METHODS  The  concentrations  of  psoralen,  isopsoralen,  neobavaisoflavone,  corylin,  psoralidin,  corylifolinin,  and
          bakuchiol  in  P.  corylifolia  extract  were  determined  by  ultra-performance  liquid  chromatography.  Based  on  the  analytic  hierarchy
          process (AHP)  and  Plackett-Burman  design,  with  the  concentrations  of  the  7  components  as  evaluation  indexes  and  the  crushing
          degree, ethanol concentration, and soaking time as factors, the extraction process of P. corylifolia was optimized by Box-Behnken
          response  surface  methodology  and  the  validation  test  was  conducted.  Zebrafish  were  divided  into  blank  control  group,  positive
          control  group (8-methoxypsoralen,  10.8  μg/mL),  and  low- ,  medium- ,  and  high-concentration  groups  of  P.  corylifolia  extract
         (500, 1 000, 2 000 μg/mL), with 6 fish in each group. The effects of P. corylifolia extract on the melanin production of zebrafish
          were  studied  by  density  analysis.  RESULTS  The  best  extraction  process  was  P.  corylifolia  powder  over  60  meshes  and  soaked  in
          80%  ethanol  for  72  hours.  The  average  comprehensive  score  of  three  validation  experiments  was  98.27,  with  an  RSD  of  1.36%,
          and  the  relative  error  was  1.02%  compared  with  the  predicted  value  of  the  fitting  equation (97.28).  Compared  with  the  blank
          control group, the melanin pigmentation of zebrafish in the low-, medium-, and high-concentration groups of P. corylifolia extract
          was  significantly  increased (P<0.01).  CONCLUSIONS  The  optimized  extraction  process  of  P.  corylifolia  is  reasonable  and
          feasible, and the obtained P. corylifolia extract can significantly promote the production of melanin in zebrafish.
