高效液相色谱法测定茶叶中儿茶素含量OA北大核心CSTPCD
Simultaneous Determination of Catechin in Different Species of Tea by RP-HPLC
目的 建立茶叶中3种儿茶素检测方法,比较目前市场不同品种茶叶中儿茶素含量差异性.方法 采用改进的高效液相色谱(HPLC)法测定了不同茶叶中3种儿茶素的含量,对5个不同品种茶叶进行了儿茶素含量差异性检查.色谱柱为Hypersil BDS C18(250 mm×4.6 mm,5 μm)柱;流动相为乙腈:0.1%柠檬酸溶液＝10:90;柱温30 ℃,波长280 nm.结果 改进的HPLC方法测定3种儿茶素在2～400 mg·L-1范围内线性关系良好…查看全部>>
Objective To establish a method for determination of three kinds catechin in tea and compare content of which from different species of tea in current market. Methods The content of three kinds of catechin was measured by modified HPLC method and difference of which was tested. The determination was performed on Hypersil BDS C18( 250 mmx 4. 6 mm,5 |xm )column with acetonitrile-0. 1% citric acid ( 10 '. 90 )as mobile phase at detection wavelength of 280 nm. A…查看全部>>
