A preparative liquid chromatographic apparatus comprising a column for separating components in a sample; a dispensing unit for dispensing an eluate from the column; a detector for the eluate; an analysis unit for the eluate; a display unit for displaying an analysis result a data storage unit; and an arithmetic control unit for controlling the display unit and the data storage unit. The analysis unit has at least one qualitative analysis unit for continuously and qualitatively analyzing the eluate. The display unit simultaneously displays a chromatogram acquired by the detector and the acquisition position of the dispensing unit and displays a correspondence relationship between each fraction and the chromatogram, and wherein by using the correspondence relationship between each fraction and the chromatogram shown in the display unit, the qualitative analysis data selected from the data storage unit is displayed on the display unit using the arithmetic control unit.
