目的:基于核磁共振(nuclear magnetic resonance,NMR)的代谢组学方法,对气虚质健康人干预前后的血浆内源性代谢物的变化进行了比较研究,寻找气虚质的可能特征代谢物。方法:招募健康气虚质20人随机分为干预组和对照组,应用补中益气丸进行1个月的干预,并对他们的血浆样品进行代谢组学检测,采用多元统计分析方法寻找补中益气丸干预气虚质血浆内源性差异代谢产物。结果:对补中益气丸干预前后血浆样本应用Simca-P软件分析提取变量重要性预测值(variable importance predictive,VIP),筛选出VIP>1,P<0.05的有差异的化学位移值45个,通过代谢产物数据库发掘对分类贡献较大的特异性代谢物30个。结论:这些差异代谢产物主要与三羧酸循环相关,说明补中益气丸调节了气虚质的能量代谢异常。而补中益气丸干预后疲劳与记忆力下降等症状的改善则可能与其能调节伽马氨基丁酸、磷脂酰胆碱、血氨的浓度有关。

Fufang Zhenzhu Tiaozhi capsules （FTZc）, which is consisted of eight traditional Chinese herbal medicines and contains multiple bioactive ingredients, is a patented and clinically approved herbal formulation for the treatment of dyslipidemia. A feasible HPLC-DAD-ELSD method was developed to simultaneously determine 15 bioactive compounds （salidroside, specneuzhenide, magnoflorine, rosmarinic acid, salvianolic acid B, columbamine, jatrorrhizine, epiberberine, coptisine, palmatine, berberine, 5,7-dimethoxycoumarin, ginsenoside Rgl, ginsenoside Rbl and oleanic acid ） in FTZc for its quality control. The multiple wavelength detection mode of DAD was used. The chromatographic separation was performed on an Ultimate XB Cls column with gradient elution. The mobile phase A （acetonitrile） and B （0.25% glacial acetic acid and 0.13% triethylamine in water, v/v） were run at a flow rate of 0.8 mL/min. The developed method showed good precision and accuracy with overall intra- and inter-day variations of 0.7%-1.9% and 0.6%-3.0%, respectively. The recoveries measured at three concentration levels, varied from 95.5% to 103.8%. The validated method was successfully applied for the simultaneous determination of 15 bioactive compounds in three batches of FTZc. The results suggested that the developed method was convenient and reliable, particularly suitable for the routine quality control of FTZc.
