[0002] Bitter melon ribosome inactivating proteins are a class of proteins extracted from bitter melon. They have N-glycosidase activity and can specifically act on the 28SrRNA of eukaryotic cell ribosomes, hydrolyzing one of the highly conserved adenine residues, thereby inactivating the ribosome and inhibiting protein synthesis. From the perspective of chemical structure, bitter melon ribosome inactivating proteins are generally single-chain or double-chain polypeptides with a relative molecular mass of about 25-30kDa.

[0043] A method for using a device for extracting and purifying ribosome-inactivating protein from bitter melon, the method comprising the device for extracting and purifying ribosome-inactivating protein from bitter melon, and the method further comprising the following steps:
[0044] Step 1: The filling pipe 3 is connected to the external pipeline, and the cut bitter melon pieces are added into the tank body 2 through the feed port 4. During the adding process, due to the presence of the conveying inclined plate 16, the bitter melon pieces will fall to the middle of the tank body 2 to prevent the bitter melon pieces from accumulating at the edge of the tank body 2. In the subsequent mixing process of the bitter melon pieces with the buffer solution, due to the shielding of the conveying inclined plate 16, the splashed liquid will not splash from the feed port 4 to the external environment. After the bitter melon pieces are added, the external buffer solution is injected into the tank body 2 through the filling pipe 3. After the liquid level reaches the set height through the tempered glass liquid level column 1, the injection of the external buffer solution is stopped. The buffer solution includes Tris-HCl, NaCl and EDTA.
[0045] Step 2: Use the external control end of the extraction and purification device to control the variable frequency drive motor 7 to operate normally, drive the drive shaft 19 and the stirring and breaking rod 18 to rotate, and use the shielding frame 146 to drive the lifting and lowering ring 143 to rotate. During the rotation of the stirring and breaking rod 18, the bitter melon pieces and the buffer solution are mixed and stirred. During the mixing process, two of the electric valves 2 are opened, and PMSF and β-mercaptoethanol in two of the tanks 2 are added to the mixture of the bitter melon pieces and the buffer solution. At the same time, the stirring and breaking rod 18 is used to fully break the bitter melon tissue and release the protein in the cells.
[0046] Step 3: After the release of the protein in the cell is completed, the variable frequency drive motor 7 is controlled to run slowly until the gap corresponds to the stirring and breaking rod 18. The linear motor 149 is controlled to move outside the arc track 144, driving the connecting plate 1410 to rotate around the support shaft 1411 as the center of the circle to unfold the internal shielding net 142. The telescopic end of the electric telescopic rod 145 extends to drive the lifting ring 143 to move downward. At this time, the stirring and breaking rod 18 will pass through the gap, and the descending shielding net 142 will press down the bitter melon pieces, so that a large amount of liquid will submerge the shielding net 142, and finally the gap will be stuck outside one of the groups of stirring and breaking rods 18, and the stirring and breaking rods 18 will be used to complete the shielding of the gap.
[0047] Step 4: Open one of the electric valves 2, add the ammonium sulfate in the corresponding feed tank 8 into the liquid, and turn on the variable frequency drive motor 7 again to drive the stirring and breaking rod 18 and the lifting ring 143 to rotate, so that the liquid is mixed with the solid ammonium sulfate and other proteins are precipitated. In the process of further extending the electric telescopic rod 145, the liquid suction head 1415 moves down and passes through the cleaning sleeve 1413, driving the telescopic tube 1416 to be stretched, and the liquid suction head 1415 enters the liquid, and the refrigerator 9, the centrifuge 11 and the liquid pump are turned on to pump the liquid into the centrifuge 11 for centrifugation to obtain high-purity bitter melon ribosome inactivation protein.
[0048] Step 5: If the liquid suction head 1415 is blocked during the liquid suction process, the electric telescopic rod 145 is controlled to continuously retract and extend, and the cleaning sleeve 1413 is used to clean the outside of the liquid suction head 1415 so that it can be used for a long time. After the liquid suction is completed, the electric telescopic rod 145 is retracted, driving the corresponding components to reset, and then the variable frequency drive motor 7 runs at high speed, and the bitter melon fragments remaining on the top of the shielding net 142 are thrown out and dropped to the bottom of the inner wall of the tank body 2. At the same time, clean water is injected into the tank body 2 through the filling pipe 3 to clean the inside of the tank body 2, and the electric valve 13 is opened to discharge the bitter melon fragments and the cleaned water.
[0049] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The telescopic end of the electric telescopic rod (145) extends to drive the lifting ring (143) to move downward. At this time, the stirring and crushing rod (18) will pass through the gap, and at the same time, the descending shielding net (142) will press down the bitter melon fragments, so that a large amount of liquid submerges the shielding net (142), and finally the gap is stuck outside one of the groups of stirring and crushing rods (18), and the stirring and crushing rods (18) are used to complete the shielding of the gap; Step 4: Open one of the electric valves 2, add the ammonium sulfate in the corresponding feed tank (8) into the liquid, and turn on the variable frequency drive motor (7) again to drive the stirring and breaking rod (18) and the lifting ring (143) to rotate, so that the liquid and the solid ammonium sulfate are mixed and other proteins are precipitated. Further, when the electric telescopic rod (145) is extended, the liquid suction head (1415) moves down and passes through the cleaning sleeve (1413), driving the telescopic tube (1416) to be stretched, and the liquid suction head (1415) enters the liquid, and the refrigerator (9), the centrifuge (11) and the liquid pump are turned on to pump the liquid into the centrifuge (11) for centrifugation to obtain high-purity bitter melon ribosome inactivation protein.
