英文摘要the linear relationship between logk(w) and s derived from molecular interactions and statistical thermodynamics was investigated by four series of different polar probe solutes. for each series of similar polar solutes, structurally related compounds with similar dipolarity/polarizability and hydrogen bonding energy, a linear relationship between logk(w) and s was obtained. the more similar the solutes, the greater were the regression coefficients obtained. for two series of solutes with different strong polar groups resulting in different dipolarity/polarizability and hydrogen bonding energy, two parallel lines were observed in the logk(w)-s plots. each line represented one series of compounds and the distance between them indicated the difference in the dipolarity/polarizability and hydrogen bonding energy. based on the parallel lines implying information on structurally related compounds in the logk(w)-s plot, a method of classification of structurally related compounds was put forward and the linear logk(w)-s correlation for unknown components in nonaqueous rp-hplc analysis of astragalus extract with isopropanol-methanol mobile phase was studied. two nearly parallel lines were obtained in the logk(w)-s plot and two series of structurally related compounds were classified in this way.
