目的 对刺五加Acanthopanax senticosus叶进行血清药物化学初步研究。方法 大鼠ig给予刺五加叶提取液,采集含药血清。采用超高效液相色谱-四级杆-飞行时间串联质谱(UPLC-Q-TOF-MS/MS)技术,通过比较相同色谱、质谱条件下刺五加叶提取物、空白血清及给药血清图谱,并利用Peakview和MetabolitePilot数据处理软件,根据质谱所提供的保留时间、精确相对分子质量及二级质谱裂解碎片来鉴定和推测其血中移行成分。结果 刺五加叶提取液ig给药后从血清中检测出19个入血成分,其中9个为原型成分,10个为代谢产物。结论 初步确定了刺五加叶的入血成分,为阐明其药效物质基础提供依据。

Objective To study the serum pharmacochemistry of leaves of Acanthopanax senticosus. Methods Rats were ig administered A. senticosus extracts and then the serum was colleted. Rapid identification of transitional constituents absorbed into blood was carried out by UPLC-Q-TOF-MS/MS. The transitional constituents were identified and speculated by Peakview and MetabolitePilot data processing software using retention time, exact relative molecular mass, and cleavage fragments of MS/MS as indexes. Results After administration of the leaves of A. Senticosus, 19 transitional constituents absorbed into blood were detected in serum, nine of them were prototype constituents and the other 10 were metabolites. Conclusion Transitional constituents of the leaves of A. senticosus absorbed into blood are preliminarily identified, which could clarify its pharmacodynamic material basis.
