| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Algicidal activity of Salvia miltiorrhiza Bung on Microcystis aeruginosa--towards identification of algicidal substance and determination of inhibition mechanism.[Pubmed:23810520]
Chemosphere. 2013 Oct;93(6):997-1004.
The present study was to isolate and identify a potent algicidal compound from extract of Salvia miltiorrhiza and study the potential inhibition mechanism on Microcystis aeruginosa. Column chromatography and bioassay-guided fractionation methods were carried out to yield neo-Przewaquinone A, which was identified by spectral analysis. The EC50 of neo-Przewaquinone A on M. aeruginosa were 4.68 mg L(-1). In addition, neo-Przewaquinone A showed relatively higher security on Chlorella pyrenoidosa and Scenedesmus obliquus, with the EC50 values of 14.78 and 10.37 mg L(-1), respectively. For the potential inhibition mechanisms, neo-Przewaquinone A caused M. aeruginosa cells morphologic damage or lysis, increased malondialdehyde content and decreased the soluble protein content, total antioxidant and superoxide dismutase activity, and significantly inhibited three photosynthesis-related genes (psaB, psbD, and rbcL). The results demonstrated the algicidal effect of neo-Przewaquinone A on M. aeruginosa and provided the possible inhibition mechanisms.
