AIM: To investigate the chemical composition of the root of Salvia przewalskii Maxim.
2.Algicidal activity of Salvia miltiorrhiza Bung on Microcystis aeruginosa--towards identification of algicidal substance and determination of inhibition mechanism.
Zhang C1, Yi YL, Hao K, Liu GL, Wang GX. Chemosphere. 2013 Oct;93(6):997-1004. doi: 10.1016/j.chemosphere.2013.05.068. Epub 2013 Jun 28.
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.
