A new ultra-performance liquid chromatography (UPLC) using conventional and chemometric calibrations was improved for the simultaneous estimation of chlorogenic acid (CA) and rutin (RUT) in leaves of Ribes L. species (R. rubrum, R. biebersteinii, R. nigrum, R. uva-crispa, R. alpinum, R. orientale, R. multiflorum and R. anatolica). The UPLC separation for CA and RUT in samples were performed on a Waters UPLC BEH phenyl column (100 mm 3 1.0 mm i.d., 1.7 mu m) and mobile phase consisting of acetonitrile and 0.1 M formic acid buffer, pH 5 3.77 (15: 85, v/v) containing 1.0 mL triethylamine in 1,000 mL mobile phase. Multi-wavelength UPLC chromatograms of CA and RUT in calibration and plant samples were obtained by the photodiode array (PDA) detection at the wavelength set from 290 to 360 nm with the interval of Delta lambda = 10 nm. Conventional UPLC-single and chemometric calibrations were subjected to the analysis of the related compounds. By using UPLC data, conventional and chemometric calibrations in the linear concentration range between 2.5 and 40.0 mu g/mL for all compounds were applied for the simultaneous quantitative analysis of CA and RUT in plant samples of seven different Ribes species.
