| 中文摘要： | 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（0.63g/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。 |
| 英文摘要： | 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，demethylation， and sulfation. |
