Study on the Fungicidal Activity of Salvia sclarea Extracted from Its Flowers

The flowers of Salvia sclarea were extracted with systematic solvents and the fungicidal activities were tested in vitro and in vivo. The bioassay results indicated that the optimal solvent extracting active components was petroleum ether. It also showed that the petroleum ether extract could markedly inhibit the various mycelial growth, its EC50 value against Botrytis cinerea was 77.20 μg/mL. In addition, protective effect and therapeutic effect of the petroleum ether extract against the Erysiphe graminis were 94.94% and 84.21%,respectively.
