The invention relates to an online low-pressure, middle-pressure and high-pressure combined two-dimension preparation liquid chromatographic system. Two one-dimension low-pressure, middle-pressure and high-pressure preparation liquid chromatographic systems are organically combined through a six-way valve and software. Pressure used by a second dimension system is not lower than pressure used by a first dimension separation system. When the first dimension system and the second dimension system are low-pressure or middle-pressure preparation liquid chromatographic systems, through switching the six-way valve, target compound directly enters a second dimension chromatographic column for second dimension separation after first dimension separation; and when pressure used by a second dimension separation system is higher than pressure used by the first dimension separation system, a trapping column is connected on the six-way valve, the target compound is adsorbed on the head of the trapping column after the first dimension separation, and then the target compound enters the second dimension chromatographic column for second dimension separation. The invention has the advantages that the contradiction between sample injection volume and separation capacity is solved, the large sample injection volume is ensured and the separation capacity of the preparation chromatographic system is greatly improved; the system structure is simple and the establishment is easy; the operation is simple and convenient and the automation can be easily realized; and the application scope is wide.
