This study was aimed to establish the method for fraction-splitting of seeds of Descurainia sophia, in order to study the stability and unoverlapping property of fractions of seeds of D. sophia. The fraction-splitting of seeds of D. sophia were obtained through the combination of various methods including decoction, distillation, extraction, ethanol precipitation and gradient elution of macroporous adsorption resin. HPLC and chemometrics software were used to analyze the stability and unoverlapping property of the fractions of D. sophia. The results showed that the chemical components from seeds of D. sophia was divided into six fractions. HPLC data and chemometrics analysis showed good stability of technology. The fraction-splitting of seeds of D. sophia was unoverlapping. It complied with the research model of chemical constituents of seeds of D. sophia which can be split and combinatorial. It was concluded that the established method for splitting fractions of seeds of D. sophia had good stability and repeatability. Each splitting fraction uncrossed others.
