【摘要】 采用高效液相色谱法,以春梢一芽二叶为研究对象,定量分析4个古茶树优系矢车菊素的含量。结果表明,高效液相色谱仪测定古茶树矢车菊素含量最合适的流动相A为超纯水,流动相B为乙腈,体积比为1∶9。古茶4号的矢车菊素含量最高,而古茶2号矢车菊素含量较低,且均显著高于或低于对照福鼎大白茶。更多还原

【Abstract】 The content of cyanidin of the ancient tea tree superior lines was analyzed by high performance liquid chromatography( HPLC). The results showed that the optimal mobile phase of HPLC analysis on the content of cyanidin of the ancient tea superior lines consisted of acetonitrile and ultrapure water( 9∶ 1,V/V). Compared with the control Fuding Dabaicha,line 4 of ancient tea tree had the highest content of cyanidin and line 2 had the lowest content of cyanidin,which both showed the significant difference from the control.更多还原
