采用超高效液相色谱(UPLC),建立不同产地生/制何首乌二苯乙烯苷(TSG)的含量测定方法和指纹图谱。大孔树脂柱处理各样品,UPLC分析,Waters ACQUITY UPLC@BEH C_(18)色谱柱(2.1 mm×50 mm,1.7 μm),乙腈-0.5%甲酸溶液梯度洗脱,流速0.3 mL·min~(-1),波长254 nm,柱温(25±5)℃。结果发现大孔树脂分离后药材二苯乙烯苷含量均在25.0%以上;成功建立不同产地生/制何首乌药材UPLC指纹图谱;标定了17个色谱峰,聚类分析不能完全将生/制首乌分开,而主成分分析可明显地将其分为两类;二苯乙烯苷是两类何首乌自变量投影重要性指标(VIP)差异最大的组分。前处理方法可获得高含量的二苯乙烯苷,测定方法简单,灵敏,可...

To establish a content determination method for 2,3,5,4'-tetrahydroxy stilbene-2-O-β-D-glucoside (TSG) of the crude/processed root of Polygonum multiflorum from different habitats in China and set up the fingerprint by using UPLC. Various samples were pretreated by macro-porous resin. Then UPLC analysis was performed on Waters ACQUITY [email protected] C18 chromatographic column (2.1 mm×50 mm, 1.7 μm) at (25±5) ℃. A binary gradient elution system was composed of acetonitrile (phase A) and 0.5% acetic acid solution (phase B). Detection was ...
