ABSTRACT

Astragali Radix is a traditional Chinese herbal medicine with a long history, which has the functions of tonifying Qi and promoting urination and granulation. Astragalosides are the main effective components of Astragali Radix, and more than 40 triterpenoid saponins have been obtained from Astragalus membranaceus and its related plants, mainly including astragalosides Ⅰ-Ⅷ, isoastragalosides Ⅰ, Ⅱ, and Ⅳ, acetylastragalosides, and soyasaponins. Astragalosides have a wide range of biological activities, such as immunomodulation, antioxidation, and neuroprotection. Nervous system diseases seriously affect people's quality of life, threaten human physical and mental health, and impose a burden on families and society. As natural drugs, astragalosides have good preventive and therapeutic effects on central nervous system diseases. This paper reviews the main pharmacological effects and mechanisms of astragalosides in the treatment of multiple sclerosis, Parkinson's disease, Alzheimer's disease, and cerebral ischemic stroke and proposes the research prospects and potential problems, aiming to provide reference for the clinical application and basic research of astragalosides.
