The results showed that the maximum specific growth rate of M. aeruginosa inhibited by water extract from R. japonica was-0. 083 d-1,and the inhibition effects on the electrical conductivity and pH of M. aeruginosa solution were significant with long duration. When the concentration of water extract from R. japonica was low,the maximum inhibition rate of M. aeruginosa was lower than 20%. When the concentration was 500 or 1 000 mg/L,the inhibition rate was higher than 50% after 144 h. It was proved that the inhibition effect of high concentrations of R. japonica on M. aeruginosa was significant and stable,which can provide reference for the control of water bloom in aquaculture water.展开更多

[Methods]With Salvia miltiorrhiza cultivated in Jizhou District as test material,HPLC was used to study the content of its pharmacological constituents( tanshinone II A,tanshinone I and danshinolic acid B). [Results] For Salvia miltiorrhiza cultivated in Jizhou District,tanshinone II A content was 0. 014%,tanshinone I content was 0. 4212%,and danshinolic acid B content was 3. 018%,higher than the standard specified in Pharmacopoeia( 2015).[Conclusions]The quality of Salvia miltiorrhiza met the requirements of medication.展开更多
