摘要: 目的 利用植物代谢组学技术对比分析何首乌(PMR)和制何首乌(PMRP)化学成分的差异,以阐明何首乌炮制前后化学成分的变化规律及炮制减毒的物质基础。方法 采用超高效液相色谱-四级杆飞行时间质谱(UPLC-Q-TOF-MS/MS)技术对何首乌和制何首乌中成分进行检测;采用主成分分析(PCA)法观察样本的整体分布趋势;采用统计学等分析技术对火山图中差异性化合物进行筛选;并将所得差异性成分与Agilent PCDL自建数据库进行比对,对其化学成分进行初步鉴定。结果 何首乌和制何首乌中的化学成分差异较大,从何首乌炮制后含量大幅减低的化合物中,初步鉴别45个化合物。结论 何首乌炮制前后化学成分存在较大的差异,尤其蒽醌(单核和双核蒽醌)和二苯乙烯苷类成分存在明显的差异,这些差异性化合物可能是何首乌炮制减毒的主要物质基础。

Abstract: Objective To explore the chemical differences between Polygoni Multiflori Radix (PMR) and Polygoni Multiflori Radix Preparata (PMRP) with the help of plant metabonomics in order to clarify the regularity of chemical composition change before and after processing and the toxicity-attenuating material basis. Methods An ultra-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) based metabolomics method was selected to analysis the composition of PMR and PMRP. Principal component analysis (PCA) method was used to observe the overall distribution trend of samples. Statistical analysis techniques were used to screen the differential compounds in the volcano plot. By comparing Agilent Natural Product Personal Compound Database and Library (PCDL), the chemical compositions were preliminarily identified. Results There were significant differences between PMR and PMRP. 45 differential compounds were tentatively identified and their contents were significantly decreased after processing. Conclusion There were significantly difference compounds between PMR and PMRP, especially for anthraquinone (mono and binuclear anthraquinone) and stilbene glycosides, which might be the main material basis for attenuating toxicity of Polygoni multiflorum Thunb.
