Basic Information
Name: Tanshinone ⅡA
CAS No.: 568-72-9
CAS Name: Phenanthro [1, 2-b] furan-10, 11-dione, 6, 7, 8, 9-tetrahydro-1, 6, 6-trimethyl
Molecular formula: C19H18O3

Molecular weight: 294.3

Plant source: root of Salvia miltiorrhlza

Physical Property
Tanshinone ⅡA is in the state of brownish red powder or cherry red acicular crystal; it is insoluble or sparingly soluble in water, and soluble in such organic solvents as dimethyl sulfoxide, ethanol, acetone, ether and benzene; the structure of tanshinone compound is stable in the solid state, but unstable in the liquid state; for example, the structure of liquid tanshinone will change according to external environments, such as light, heat, pH, etc.; after light irradiation and oxidation, the liquid tanshinone will turn into the hydroxy tanshinone IIA.

Source
Tanshinone ⅡA is from the dried root and rhizome of Salvia miltiorrhiza Bge. and the root of Salvia sclarea L.
