摘要
目的:研究黑骨藤在正常及佐剂性关节炎(AA)大鼠体内的代谢产物,探究类风湿性关节炎(RA)对黑骨藤有效成分在大鼠体内代谢的影响。方法:采用弗氏完全佐剂制备AA大鼠模型;运用UPLC-Q TOF MSE方法,采用ACQUITY UPLC BEH C_(18)(100 mm×2.1 mm,1.7μm)色谱柱,以0.01%甲酸水-0.01%甲酸乙腈为流动相梯度洗脱,流速0.25 mL·min^(-1),采用电喷雾离子源,在负离子模式下,对正常和AA模型大鼠灌服黑骨藤提取物后的血浆、尿液和粪便进行分析。结果:在正常大鼠体内和AA模型大鼠体内分别检测到2、3个原型成分,32、35个代谢产物,代谢途径主要包括单咖啡酰基奎宁酸还原、甲基化、开环裂解、葡萄糖醛酸化,二咖啡酰基奎宁酸还原、甲基化、乙酰化、异构化、硫酸酯化、葡萄糖醛酸化等。结论:AA模型大鼠血浆和尿液中的代谢产物比正常大鼠更具多样性,RA疾病状态可能会影响黑骨藤有效成分在体内的代谢途径。
Objective:To investigate the metabolites of Periploca forrestii in plasma,urine,and feces of normal and adjuvant arthritis(AA)rats,and explore the effect of rheumatoid arthritis(RA)on the metabolism of active components of P.forrestii.Methods:AA rat model was made by means of Freund’s complete adjuvant.Plasma,urine and feces of normal and AA rats were analyzed by UPLC-Q-TOF-MS E method using ACQUITY UPLC BEH C_(18)(100 mm×2.1 mm,1.7μm)column with 0.01%formic acid water-0.01%formic acid acetonitrile as mobile phase gradient elution at a flow rate of 0.25 mL·min^(-1),and electrospray ion source under negative ion mode.Results:Two and three prototype components,32 and 35 metabolites were detected in normal rats and AA model rats.The metabolic pathways mainly include monocaffeoylquinic acid reduction,methylation,ring-open⁃ing cleavage,glucuronidation,dicaffeoylquinic acid reduction,methylation,acetylation,isomerization,sulfation glucuronidation,etc.Conclusion:The metabolites in plasma and urine of AA model rats are more diverse than those in normal rats,and the disease state of RA may affect the metabolic pathway of effective components of P.forrestii in the body.
