Sodium tanshinone IIA sulfonate hydrate and preparation method and use thereof

摘要

The present invention relates to sodium tanshinone IIA sulfonate hydrates as well as preparation methods and uses thereof. The sodium tanshinone IIA sulfonate hydrates have molecular formla of C₁₉H₁₇NaO₆S.nH₂O, wherein n=0.5-4.0. The sodium tanshinone IIA sulfonate hydrates of the present invention have better storage stability than anhydrous sodium tanshinone IIA sulfonate.
