          摘  要  目的  建立黄芩汤(HQD)的指纹图谱,拆分相态并筛选抗皮肤癣菌活性相态,进行谱效关系研究。方法  采用高效液相
          色谱法,以黄芩苷为参照峰,采用《中药色谱指纹图谱相似度评价系统(2012版)》绘制10批HQD的指纹图谱并进行相似度评价,
          确定共有峰;采用高速离心与透析相结合的方法对HQD进行相态拆分并对其进行表征,同时测定HQD及其不同相态抗皮肤癣菌
          的最小抑菌浓度(MIC);以37个共有峰的峰面积为自变量,MIC为因变量,采用SPSS 21.0软件进行Pearson相关性分析。结果  10
          批HQD共有37个共有峰,相似度均大于0.99;共指认出10个成分,分别为芍药内酯苷、芍药苷、芹糖甘草苷、黄芩苷、千层纸素A苷、
          汉黄芩苷、黄芩素、甘草酸、汉黄芩素、千层纸素A。HQD共拆分成沉淀相态(HQD-P)、真溶液相态(HQD-S)和纳米相态(HQD-N)3
          个相态;HQD-P冻干粉呈不规则颗粒状,平均粒径为4.670~91.522 μm;HQD-S冻干粉呈均匀片状,未检测到粒径;HQD-N冻干粉
          呈球形,粒径为(129.0±12.9)nm。在同等给药剂量下,各相态抗皮肤癣菌 MIC 由低到高依次为 HQD-N(4.64 mg/mL)<HQD
         (5.85 mg/mL)<HQD-P(7.37 mg/mL)<HQD-S(12.89 mg/mL)。Pearson相关分析结果显示,37个共有峰中,有25个共有峰(含已
          指认的10个成分)峰面积与MIC呈显著负相关(相关系数绝对值>0.95且P<0.05)。结论  10批HQD的化学成分组成一致性较
          好;HQD-N为该方的活性相态,其中芍药苷、芹糖甘草苷、黄芩苷等10个成分可能是HQD抗皮肤癣菌的有效成分,且其抗皮肤癣
          菌作用强弱与这些成分含量及物理相态相关。

          ABSTRACT   OBJECTIVE  To  establish  the  fingerprint  of  Huangqin  decoction (HQD),  to  separate  the  phase  states  and  screen
          the active phase states of antidermatophytic activity so as to study the spectrum-effect relationship. METHODS HPLC method was
          adopted using baicalin as reference, the fingerprints of 10 batches of HQD were drawn and the similarity evaluation was carried out
          using the Similarity Evaluation System of Chromatographic Fingerprint of TCM (2012 edition) to determine the common peak; the
          phase states of HQD were separated and characterized by high-speed centrifugation and membrane dialysis. The minimum inhibitory
          concentrations (MIC)  of  HQD  and  its  different  phase  states  against  Trichophyton  mentagrophytes  were  determined  simultaneously.
          Using  the  peak  area  of  37  common  peaks  as  independent  variable,  MIC  as  dependent  variable,  Pearson  correlation  analysis  was
          performed by using SPSS 21.0 software. RESULTS A total of 37 common peaks were obtained in HPLC fingerprints of 10 batches
          of HQD, with the similarity higher than 0.99. Ten components were identified, such as albiflorin, paeoniflorin, liquiritin apioside,
          baicalin,  melaleuca  glycoside A,  wogonoside,  baicalein,  glycyrrhizic  acid,  wogonin  and  oroxylin A.  HQD  was  split  into  3  phase
          states, such as precipitation phase (HQD-P), solution phase (HQD-S) and nano phase (HQD-N). The morphology of HQD-P was
          irregular  granular,  and  the  average  particle  size  was  4.670-91.522  μm.  The  morphology  of  HQD-S  was  uniform  flakes,  and  no
