Problems solved by technology

However, since tanshinone IIA is a highly oxidized polyphenyl ring structure, tanshinone IIA sodium sulfonate injection needs to be stored in an airtight, cool and dark place, which is difficult to store
Oxidation and polymerization are easy to occur in the solution state, thereby reduc
