Salvianolic Acid B Prevents Bone Loss in Prednisone-Treated Rats through Stimulation of Osteogenesis and Bone Marrow Angiogenesis
Figure 1
Structure of Salvianolic acid B and Tanshinol.
Salvianolic acid B consists of three molecules of Tanshinol (D (+) β-3,4-dihydroxyphenyl lactic acid, danshensu) and a molecule of caffeic acid. Sal B can be converted in vivo to Tanshinol, another water-soluble bioactive ingredient of Salvia miltiorrhiza Bunge, with similar function to Sal B.
