Methyl tanshinonate is a tanshinone, that can be isolated from Salvia miltiorrhiza (S. miltiorrhiza) Bunge (Lamiaceae). Methyl tanshinonate is a potent inhibitor of Mpro enzyme in SARS-CoV (IC50 = 21.1 μM). Methyl tanshinonate can be used for diabetes and SARS-CoV research[1][2][3].

(1) extraction: divided into two steps, the solvent used can be water or any kind of alcohols, ketones and esters solvents, or a mixture of these solvents in a certain proportion, or from these solvents with acids, alkalis, salts formulated as acidic or a
