摘    要:目的:采用高效液相色谱-质谱联用法测定牡丹皮中没食子酸的含量,研究通过多种机制发挥药物的抗肿瘤作用。方法:采用高效液相色谱-质谱联用法在Diamonsil C18色谱柱(5μm,4.6 mm×250 mm),流动相为甲醇-0.05%磷酸水溶液梯度洗脱;流速为0.8 ml/min;检测波长为270 nm;柱温为25℃;分离测定牡丹皮中没食子酸的含量。结果:牡丹皮中没食子酸含量为1.8 mg/g,RSD=1.7%。结论:牡丹皮中没食子酸含量较高,其主要成分没食子酸与其对脂肪酸合成酶(FAS)的抑制作用有一定的相关性。

关 键 词:牡丹皮  高效液相色谱-质谱  没食子酸  脂肪酸合成酶

Abstract:Objective: To detect gallic acid in Paeonia suffruticosa Andr. by high performance liquid chromatography-mass spectrometry. Methods: A method for determining gallic acid in Paeonia suffruticosa Andr. by HPLC-MS is described. The operating conditions were Diamonsil C18 column (5μm, 4.6×250 mm) at room temperature, methanol-0.05% phosphoric acid solution as mobile phase by step gradients elution at a flow of 0.8 ml/min and UV detection at 270 nm. Results:The content of gallic acid is 1.8 mg/g. The relative standard deviation of gallic acid is 1.7%. Conclusion:The content of gallic acid in Paeonia suffruticosa Andr. is high, which may be related to the inhibition of FAS.
Keywords:Paeonia suffruticosa Andr  HPLC-MS  Gallic acid  Fatty acid synthase
