摘要:

为了阐明黄连解毒汤神经保护作用与化学成分的相关性, 本实验将黄连解毒汤水提取物分为四个不同极性段, 运用HPLC-DAD-ESI-MS/MS 鉴定了四个极性段的17个主要化学成分, 并运用HPLC-DAD对其中11个化合物进行了定量研究。方法学考察显示线性良好(r2, 0.9994-0.9999), 重复性和稳定性的RSD值分别为1.66%-3.67%, 1.26%-4.77%, 回收率(95.24%-105.41%, RSD, 0.29%-2.69%)。在化学研究的基础上, 运用PC12细胞核元代神经元细胞对黄连解毒汤及四个不同极性段神经保护作用进行了考察。结果表明水提取物和正丁醇部分比其他极性段的神经保护作用更强。根据化学成分的定性和定量分析, 可以推断在水提物和正丁醇部位含量明显较高的环烯醚萜和生物碱与神经保护作用相关。

Abstract: Huang-Lian-Jie-Du-Decoction (HLJDD) has been widely used for the treatment of Alzheimer’s disease (AD) in clinic. However, the relationship between its chemical profile and neuroprotective bioactivity was not clearly clarified yet. In present study, the water extract of HLJDD and subsequent three polarity fractions divided by different reagents were investigated. A total of 17 chromatographic peaks were confirmed by comparison with standards and their UV, MS spectra. Among them, 11 major compounds were determined by HPLC-DAD method with good linear regression relationship (r2, 0.9994-0.9999), precisions (inter-day precision RSD, 0.79%-1.07%; intra-day precision RSD, 1.59%-2.10%), repeatability (RSD, 1.66%-3.67%), stability (RSD, 1.26%-4.77%) and recovery (95.24%-105.41%, RSD, 0.29%-2.69%). Furthermore, PC12 cells and primary neurons cells were used for the neuroprotective effective assessment of aforementioned four samples from HLJDD. The total aqueous extract and n-butanol extract of HLJDD presented more significant effects than the other two parts. According to their quality and quantity determination results, iridoids and alkaloids have a positive correlation with the neuroprotective effectiveness of HLJDD.
