The utility model provides a tobacco leaf extraction centrifuge tube, belongs to the technical field of centrifuge tubes, and aims to solve the problems that the existing tobacco leaf extraction centrifuge tube is relatively single in structure and function, a virus solution in the centrifuge tube is relatively slow in flow rate, so that the purification efficiency of virions is relatively low, and the virions need to be sealed after being purified; the centrifugal tube comprises a centrifugal tube main body, and a fixing ring is arranged in a tube cavity of the centrifugal tube main body; a limiting round rod is arranged on the fixing ring; and a sliding sleeve is arranged above the fixing ring. When the centrifugal tube main body is put into a centrifugal machine to swing, the sliding sleeve and the piston plate can slide downwards along the limiting round rod, and a virus solution in the centrifugal tube main body can be pressurized through the mutual matching of the sealing plug and the piston plate and t
