Rhodiola sachalinensis is a very precious medicinal plant. Rhodiola sachalinensis sachalinensis in China is also very rich in varieties, known as "God grass". Rhodiola sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis sachalinensis. It has been successfully cultivated in China. The Soviet Union has put Rhodiola on the market as a high-grade tonic to improve human intelligence and physical strength. It can be seen that Rhodiola is a kind of health medicine beneficial to human body.

    Alzheimer's disease is a common and frequently occurring disease that endangers the physical and mental health of the elderly. Alzheimer's disease has become a global research topic. At present, there are still no good prevention and treatment measures for Alzheimer's disease. The degree of intelligence deficiency in senile dementia patients is related to cholinergic activity in cerebral cortex and hippocampus. In the early 1970s, Deutsch et al. Found that the cholinergic system is related to memory formation and storage. At present, they believe that the central nervous cholinergic dysfunction is likely to be the pathogenesis of various types of dementia. Chat is an enzyme that catalyzes the synthesis of ACh. The decrease of ChAT activity is related to the formation of lipofuscin. Chat is an enzyme located in the membrane, which indicates the state and function of cells. Salidroside can increase the content of ACh and the activity of chat, so that it can protect the central cholinergic system and improve the learning and memory behavior and dementia state of aging and senile dementia model rats.

        At present, it is generally accepted that the aging process of Alzheimer's disease and the body is related to the degenerative changes of body tissues and cells, which is mainly caused by the toxic and side effects of free radicals. Free radicals can cause abnormal lipid metabolism and produce excessive LPO and lipofuscin, thus damaging the functions of cell membranes, organelles and enzymes, and causing structural and functional changes such as DNA mutation, cross-linking, single strand breaks, etc. Further, it leads to the disorder of cell protein synthesis and metabolism, resulting in cell degeneration, degeneration and apoptosis. Rhodiola can scavenge free radicals, promote cell metabolism and protein synthesis; Prevent lipofuscin accumulation and nerve fiber tangle formation. As an antioxidant, Rhodiola can enhance the functional activities of the central cholinergic system, eliminate free radicals, promote cell metabolism, enhance cell vitality, delay cell aging, self cell degradation, degeneration and apoptosis, so as to improve the structure and function of the body and enhance the vitality of the body.RhodiolaIt has the functions of brain health, intelligence, memory enhancement and anti-aging, and has certain preventive and protective effects on experimental dementia. The experiment found that salidroside has anti-aging effects on older mice.
