Purpose In order to investigate the constituents from the roots of Hedychium yunnan-ense.
Method Compounds were isolated from EtOH extract of H. yunnanense by chromatography methods. Their structures were identified by spectral analysis.
Conclusion Six compounds were isolated from EtOH extract of the roots of H. yunnanense and their structures were identified as 5-hydroxy-3,7,4′-trimethoxyflavone (1), 3,5,7,4′-tetramethoxyflavone (2), 6,7,8,4′-tetramethoxyflavone (3), 4-hydroxy-3-methoxybenzaldehyde (4), 3,4-dimethoxyphenol (5), methyl ferulate (6), respectively.
Conclusion Compounds 1-6 were isolated from this plant for the first time.
