[Recent advances in anti-aging study of 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucopyranoside--a main component of Polygonum multiflorum].

Aging is an inevitable process of life caused by a combination of organs and tissues events which manifests as loss of structure and function. It is accompanied with organ hypofunction, decline in defense against stress and energy metabolism, and lots of age-related diseases. Therefore, it is critical to understand the mechanism of aging, as well as to discover new drugs to slow aging. Polygonum multiflorum has long been recognized in traditional Chinese medicine as anti-aging medicine. Interestingly, its extract has been shown to prolong lifespan in drosophila and elegans. Tetrahydroxystilbene glucoside (TSG), the main ingredient of P. multiflorum, shares a strong structural similarity with resveratrol, a well-known anti-aging natural product. This review summarized up-to-date literature reports and our laboratory findings on the mechanism of TSG anti-aging efficiency and function against age-related disease. It could provide reference for searching for anti-aging tradition Chinese medicine.
