当归芍药散含药血浆UPLC-UV指纹图谱研究

目的建立当归芍药散含药血浆指纹图谱并分析给药后血中移行成分。方法大鼠ig给予当归芍药散提取液,制备11组含药血浆,采用超高效液相色谱-紫外(UPLC-UV)法构建11组当归芍药散含药血浆的指纹图谱,运用指纹图谱参数共有峰、相似度进行分析。超高效液相色谱-四级杆-飞行时间串联质谱(UPLC-Q/TOF-MS)法分析大鼠ig当归芍药散后血中移行成分。结果建立了当归芍药散含药血浆指纹图谱,通过对含药血浆、空白血浆图谱进行比对,指定了15个共有峰,相似度在0.933以上。初步鉴定了当归芍药散入血的15个成分,其中原型成分10个和代谢产物5个。结论当归芍药散含药血浆指纹图谱研究为进一步血中移行成分的研究提供了基础。

Studies on plasma fingerprint of Danggui Shaoyao Powder by UPLC-UV

Objective To establish the plasma fingerprint of Danggui Shaoyao Powder (DSP) for the analysis of the transitional components in rat plasma after administration of DSP extracts Methods Eleven batches of rat plasma were prepared after oral administration and the plasma fingerprint was established by UPLC-UV. The transitional components in rat plasma after administration of DSP extracts was analyzed by UPLC-Q/TOF-MS. Results The plasma fingerprints of common peaks for 11 batches of DSP were established to ascertain the optimized blood collection time, and the method was used to process the plasma. Fifteen common peaks were detected in plasma fingerprint, and the similarity were both higher than 0.933. The methodology of plasma pharmacochemistry was adopted to analyze the common peaks, and 15 transitional components, including 10 prototype components and five metabolites were identified. Conclusion The established plasma fingerprint of DSP provide the basis for the further study of transitional components.
