[Chemical Constituents from Goodyera schlechtendaliana]
Objective:
To study the chemical constituents of Goodyera schlechtendaliana.
Methods:
Compounds were isolated through various chromatographic techniques and identified by spectroscopic analysis and comparison with those in literature.
Results:
Seven compounds were obtained from 95% ethanol extract. Their structures were identified as syringaldehyde (I), 5-hydroxymethylfurfural (II) , alloimperatorin (III), vanillic acid (IV), ferulic acid (V), glyceroyl monopalmitate (VI) and β-sitosterol (VII).
Conclusion:
Compounds II- VII are reported from this genus and compounds I - VII are reported from this plant for the first time.
