Abstract: From the fresh root of Salvia sonchifolia C.Y.Wu,nine polyphenolic compounds,protocatechualdehye,protocatechuic acid,caffeic acid,R-(+)-β-D-(3,4-dihydroxyphenyl)-lactic acid,3,4-dihyroxyphenyl ethanol ketone,rosmarinic acid ,methyl rosmarinate,lithospermic acid and lithospermic acid B are isolated.Their structures were identified by spectral method. The result shows that Salvia sonchifolia coutains the phenolic constituents which are similar to that of medical Salvia.
