          摘   要  目的  分析鸡骨草水提物灌胃大鼠后的入血和入肝成分,并推测其可能的代谢途径,为鸡骨草的药效物质基础分析提供
          参考。方法  将雄性SD大鼠随机分为鸡骨草给药组(0.63 g/kg,以生药量计)、空白组,分别单次灌胃相应药液/超纯水,收集各组大
          鼠的血浆和肝脏样品。采用超高效液相色谱-四极杆-飞行时间质谱(UPLC-Q-TOF/MS)技术对鸡骨草水提物化学成分及入血、入
          肝成分进行鉴定。结果  从鸡骨草水提物中共鉴定了30个化学成分,主要为生物碱类、黄酮类、有机酸类和环烯醚萜类(如相思子
          碱、夏佛塔苷和异夏佛塔苷等)等。从血浆样品中鉴定了10个原型成分和9个代谢产物(如原儿茶酸脱羧化硫酸化代谢产物、对羟
          基苯甲酸还原化硫酸化代谢产物等),从肝脏样品中鉴定了6个原型成分和5个代谢产物(如对羟基苯甲酸硫酸化代谢产物、对羟
          基苯甲酸脱羧化硫酸化代谢产物等)。代谢途径主要包括羟基化、去甲基化、甲基化、硫酸化、葡萄糖醛酸化等。结论  生物碱类、
          黄酮类、有机酸类是鸡骨草水提物入血和入肝的主要成分,主要涉及羟基化、去甲基化、硫酸化等代谢途径。

          ABSTRACT    OBJECTIVE  To  analyze  the  chemical  components  that  were  the  absorbed  in  blood  and  liver  tissue  of  rats  after
          intragastric administration of aqueous extract from Abrus cantoniensis, and to speculate its possible metabolic pathways, providing
          reference for basic analysis of pharmacological substance in A. cantoniensis. METHODS Male SD rats were randomly divided into
          A.  cantoniensis  group (0.63  g/kg,  calculated  by  crude  drug)  and  blank  group;  they  were  given  relevant  drug  solution/ultrapure
          water  intragastrically.  After  a  single  dose,  plasma  and  liver  samples  of  rats  in  each  group  were  collected.  UPLC-Q-TOF/MS
          technology  was  used  to  identify  chemical  components  that  were  absorbed  in  the  blood  and  liver  tissue  of  rats.  RESULTS  Totally,
          30 chemical constituents were identified from the water extracts of A. cantoniensis, including alkaloids, flavonoids, organic acids,
          iridoids (such  as  L-abrine,  schaftoside,  isoshaftoside).  Ten  prototype  components  and  nine  metabolites (such  as  decarboxylation
          and  sulfation  metabolites  of  protocatechuic  acid,  reduced  sulfated  metabolites  of  p-hydroxybenzoic  acid)  were  identified  from
          plasma  samples;  six  prototype  components  and  five  metabolites (such  as  sulfated  metabolites  of  p-hydroxybenzoic  acid,
          decarboxylation  and  sulfation  metabolites  of  p-hydroxybenzoic  acid)  were  identified  from  liver  samples.  The  main  metabolic
          pathways  included  hydroxylation,  demethylation,  methylation,  sulfation,  glucuronidation,  etc.  CONCLUSIONS  Alkaloids,
          flavonoids and organic acids are the main components of the aqueous extract from A. cantoniensis that are absorbed into the blood
                                                              and  liver,  their  metabolism  mainly  involves  hydroxylation,
