      (Topological models of the retention index for chiral organic acids) (Chinese)
      M. LI (Li Mingjian), Y. WANG (Wang Yuxiao), H. FENG (Feng Hui), CH. FENG (Feng Changjun)* (*Sch. Of Chem. & Chem. Eng., Xuzhou Inst. of Technol., Jiangsu, Xuzhou 221111, China)

      Chinese J. Chromatogr. 32 (3), 242-247 (2014). Definition of novel molecular connectivity indices and calculation of the indices for 18 chiral hydroxyl acids and amino acids, based on Kier’s molecular connectivity indices and conjugated matrix. Study of the quantitative structure-retention index relationship (QSRR) between the retention index of the chiral organic acids and the chiral connectivity indices by multivariate statistical regression. The best four-parameter QSRR model was set up through leaps-and-bounds regression analysis. The traditional correlation coefficient and the cross-validation correlation coefficient of leave-one-out were given, respectively. The results demonstrated that the model was highly reliable and had good predictive ability from the statistical point of view. From the parameters of the model, it is known that the dominant influence factors on the retention index were the two-dimensional molecular structure characteristics and the space factors such as the chiral characteristics, the flexibility and the puckered degree of the molecules of the chiral organic acids. The results also indicated that the introduced chiral connectivity indices had good rationality and validity for the characterization of the retention indices for the chiral organic acids, thus, provided an effective method for predicting the retention indices of chiral organic acids.

      J. Planar Chromatogr. 29, 22-29 (2016). HPTLC of 1-fluoro-2,4-dinitrophenyl-5-l-valine amide diastereomeric derivatives of aspartic acid, cysteine, and histidine on RP-18W with 40–80 % of acetonitrile in water, in 10 % steps. The retention analysis showed that retention of solutes diminished when the mobile phase became less polar.
