    Algicidal activity of Salvia miltiorrhiza Bung on Microcystis aeruginosa--towards identification of algicidal substance and determination of inhibition mechanism.[Pubmed: 23810520]
    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.
    METHODS AND RESULTS:
    Column chromatography and bioassay-guided fractionation methods were carried out to yield neo-przewaquinone A, which was identified by spectral analysis. The EC50 of Neoprzewaquinone 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, Neoprzewaquinone 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).
    CONCLUSIONS:
    The results demonstrated the algicidal effect of Neoprzewaquinone A on M. aeruginosa and provided the possible inhibition mechanisms.

    Chemical constituents in the roots of Salvia przewalskii Maxim.[Pubmed: 12958839]
    To investigate the chemical composition of the root of Salvia przewalskii Maxim.
    METHODS AND RESULTS:
    Compounds were isolated by silica gel column chromatography. Structures of these compounds were elucidated by spectral analysis (EI-MS, FAB-MS, 1HNMR, 13CNMR, 1H-1H COSY, 1H-13C COSY, HMBC, NOESY) and phytochemical properties. Eight compounds were isolated and identified as: tanshinone II-A (I), crypotanshinone (II), przewaquinone A (III), sugiol (IV), ursolic acid (V), 2 alpha, 3 alpha-dihydroxy urs-12-ene-28-acid (VI), oleanolic acid (VII), and Neoprzewaquinone A (VIII).
    CONCLUSIONS:
    Compound VIII is a new compound, and compound II, IV, V, VI and VII are isolated from this plant for the first time.
