Chenchen Zhu

Abstract

Objective To study on chemical constituents of Isodon lophanthoides var.gerardianus.Methods The chemical constituents were isolated by chromatographic methods and structurally elucidated by spectral analysis.Results Five compounds were obtained and identified as 2β,3α,24-trihydroxy ursolic acid (1),rosmarinic acid (2),methyl rosmarinate (3),caffeic acid (4) and ferulic acid (5).Conclusion Compound 1 is isolated from Isodon lophanthoides var.gerardianus for the first time.
