Embodiment 1
[0039] An insect-specific polyamine small molecule toxin, the relative molecular weight of the insect-specific polyamine small molecule toxin is 622.3971; its molecular formula is C 28 h 50 N 10 o 6 , its structural formula is as follows:
[0040]
[0041] The method for purifying the above-mentioned insect-specific polyamine small molecule toxins specifically comprises the following steps:
[0042] The first step is the ultrafiltration of venom, specifically: the venom collected by electrical stimulation is separated by ultrafiltration tubes, repeated several times, and the filtrates are combined to obtain a non-protein small molecule toxin mixture containing insect-specific polyamine small molecule toxins . Here, the venom is the venom of the Eurasia grandis; the ultrafiltration membrane in the ultrafiltration tube is a semi-permeable membrane that allows molecules below 3KDa to pass through; the separation is specifically centrifuged at a speed of 8000-12000rpm for 8-1...
