Polyphenolic Constituents of Salvia sonchifolia

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-dihydroxyphenyl 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.
