Objective: To investigate the chemical constituents of Spiranthes sinensis. Method: The constituents of the EtOAc-soluble portion of 95% ethanol extract were isolated and purified by means of chromatography. Compounds were identified by their physical characteristics and spectral features. Result: Five compounds were isolated and identified as 3(-hydroxy-urs-12-en-28-oicacid (1)
5-hydroxyl-7
3
4'-timethoxy-flavone (2)
sinetirucallol (3)
daucosterol (4)
and β-sitosterol (5). Conclusion: Compound 1 was first seperated from orchidaceae and compounds 2 was isolated from this plant for the first time.
