Spermidine, also known as spermidine trihydrochloride, is a polyamine. It is widely distributed in organisms and is biosynthesized (butanediamine) and adenosylmethionine. Spermidine can inhibit neuronal synthases, bind and precipitate DNA; it can also be used to purify DNA-binding proteins and stimulate T4 polynucleotide kinase activity. On September 1, 2013, a collaborative study by scientists from Germany and Austria showed that spermidine may prevent the onset of Alzheimer's disease.

| Conclusion: Conform with specification. | ||
Spermidine has different effects on proteins of different molecular weights. Some high molecular weight bands are significantly enhanced with the extension of spermidine treatment time, indicating that there may be protein synthesis, but this part of protein accounts for a small percentage of the total protein. The effect on medium molecular weight and low molecular weight proteins is not obvious. The main proteins remain basically unchanged during the 72-hour treatment process. From these results, it can be inferred that the role of proteins of different molecular weights in the aging process may be different. Some high molecular weight proteins may play a key role in controlling the aging process of leaves. Once these proteins begin to degrade, aging is inevitable, and controlling the degradation of these proteins can delay the aging process. The reason why spermidine can delay its aging may be that it promotes the synthesis of these proteins or prevents their degradation.
