          摘   要  目的  制备芎芷石膏汤可溶性微针,并进行表征及体外透皮性能考察。方法  采用两步离心法制备芎芷石膏汤可溶性微
          针,并从基质溶液流动性、微针成形性、针尖硬度等方面评价其成形性和机械性能。以该可溶性微针的活性成分(绿原酸、阿魏酸、
          羌活醇、欧前胡素、藁本内酯、异欧前胡素)为考察指标,从外观形态、机械强度、溶解性能、皮肤屏障恢复性能、载药量进行表征,并
          采用Franz扩散池法考察其体外透皮性能。结果  本研究所制备的芎芷石膏汤可溶性微针针尖呈圆锥形,分布均匀且粗细相同,机
          械性能良好;针尖部分可在刺入大鼠皮肤2 h后几乎全部溶解,且皮肤屏障恢复性能良好;微针中绿原酸、阿魏酸、羌活醇、欧前胡
          素、藁本内酯、异欧前胡素的载药量分别为每片(87.04±1.12)、(67.69±1.23)、(20.65±0.17)、(35.00±0.11)、(153.83±0.21)、
         (23.52±0.50) μg。体外透皮实验结果显示,该微针中 6 种活性成分 72 h 的累积释放率分别为 36.94%、56.72%、19.36%、57.98%、
          11.06%、35.19%。结论  本研究成功制备了芎芷石膏汤可溶性微针,其成形性、机械性好,背衬柔韧,可促进药物透皮吸收。

          ABSTRACT    OBJECTIVE  To  prepare  Xiongzhi  shigao  decoction  soluble  microneedles,  characterize  it  and  investigate  its
          transdermal  properties  in  vitro.  METHODS  Two-step  centrifugal  method  was  used  to  prepare  Xiongzhi  shigao  decoction  soluble
          microneedles.  The  formability  and  mechanical  property  of  the  microneedles  were  evaluated  from  aspects  of  stroma  fluidity,
          microneedle  formability,  needle  hardness,  etc.  The  appearance,  mechanical  strength,  dissolution  performance,  skin  barrier
          recovery performance and  drug  loading of  the  prepared microneedles  were  characterized  by  using  active components of  the  soluble
          microneedle (chlorogenic  acid,  ferulic  acid,  notopterol,  imperatorin,  ligustilide,  isoimperatorin)  as  indicators.  The  in  vitro
          transdermal  performance  was  investigated  by  Franz  diffusion  cell.  RESULTS  The  soluble  microneedle  tips  of  Xiongzhi  shigao
          decoction  prepared  in  this  study  were  conical,  evenly  distributed  and  of  the  same  thickness,  with  good  mechanical  properties;  the
          tip of the needle could be almost completely dissolved after being penetrated into the skin of rats for 2 hours, and the skin barrier
          recovery  performance  was  good;  the  drug  loading  of  chlorogenic  acid,  ferulic  acid,  notopterol,  imperatorin,  ligustilide  and
          isoimperatorin  were (87.04±1.12), (67.69±1.23), (20.65±0.17), (35.00±0.11), (153.83±0.21)  and (23.52±0.50)  μg  per
          patch  respectively.  The  results  of  in  vitro  transdermal  study  showed  that  cumulative  release  rates  of  6  active  components  in  this
          microneedle  after  72  hours  were  36.94%,  56.72%,  19.36%,  57.98%,  11.06%  and  35.19%,  respectively.  CONCLUSIONS
          Xiongzhi  shigao  decoction  soluble  microneedles  are  prepared  successfully  in  this  study  and  have  good  formability,  mechanical
          properties and pliable backing, which can significantly promote the transdermal drug delivery.
