          摘  要  目的  分析木姜叶柯叶的入血、入脑成分,为明确其防治中枢神经系统疾病的药效物质基础提供参考。方法  制备木姜叶
          柯叶醇提物以及灌胃液、灌流液。以大鼠为研究对象,通过在体肠灌流法和封闭肠环法制备肠壁代谢、肠道菌代谢、肝代谢全血样
          本,通过灌胃给药方法制备综合代谢全血样本和脑组织、脑脊液样本。采用超高效液相色谱-高分辨质谱技术,分析鉴定木姜叶柯
          叶的化学成分及其在大鼠体内的入血及入脑成分。结果  从木姜叶柯叶中共鉴定出66个化学成分,主要为黄酮类、有机酸等。从
          肠壁代谢、肠道菌代谢、肝代谢与综合代谢全血样本中分别鉴定出16、13、11、5个原型成分,从脑组织样本中鉴定出4个原型成分,
          从脑脊液样本中鉴定出9个原型成分,其中根皮苷、三叶苷、根皮素-2-O-丙二酰己糖苷、根皮素为各样本的共有成分。结论  木姜
          叶柯叶入血、入脑原型成分中的根皮苷、三叶苷、根皮素等可能是其治疗中枢神经系统疾病的药效物质基础。

          ABSTRACT   OBJECTIVE To analyze the prototype components absorbed into blood and brain of Lithocarpus litseifolius leaves,
          so  as  to  provide  a  reference  for  clarifying  the  pharmacological  material  basis  of  its  prevention  and  treatment  of  central  nervous
          system diseases. METHODS The ethanol extract of L. litseifolius leaves, as well as the gastric lavage fluid and perfusion solution
          were  prepared.  Using  rats  as  subjects,  plasma  samples  of  intestinal  wall  metabolism,  intestinal  flora  metabolism  and  hepatic
          metabolism were prepared via in situ intestinal perfusion and closed intestinal loop method; while comprehensive metabolic plasma
          samples,  brain  tissue  samples,  and  cerebrospinal  fluid  samples  were  collected  after  intragastric  administration.  UPLC-HRMS
          technology was utilized to analyze and identify chemical components and prototype components absorbed into blood and brain of L.
          litseifolius  leaves.  RESULTS  A  total  of  66  chemical  constituents  were  identified  in  L.  litseifolius  leaves,  primarily  consisting  of
          flavonoids,  organic  acids,  and  others.  A  total  of  16,  13,  11,  and  5  prototype  components  were  identified  in  intestinal  wall
          metabolism,  intestinal  flora  metabolism,  hepatic  metabolism,  and  comprehensive  metabolic  plasma  samples,  respectively.
          Additionally, 4 prototype components were detected in brain tissue and 9 in cerebrospinal fluid. Phloridzin, trilobatin, phloretin-2-
          O-malonyl  hexoside,  and  phloretin  were  identified  as  common  components  across  all  sample  types.  CONCLUSIONS  Prototype
          components absorbed into blood and brain of L. litseifolius leaves, such as phloridzin, trilobatin, phloretin, and other components
          may serve as the pharmacological material basis for their therapeutic effects on central nervous system diseases.
