Objective: To study the chemical constituents of the ethyl acetate portion in the herb of Nervilia fordii from guangxi.
Methods: The constituents were separated and purified by using column chromatography with silica gel. These compounds were identified by their physical and spectral data.
Results: Five compounds were isolated and identified as norleucine (crystal I), 24 (S/beta)-dihydrocycloeucalenol-(E)-p-hydroxy cinnamate (crystal II) , rhamnocitrin (crystal III), rhamnazin (crystal IV), daucosterol (crystal V).
