[Studies on the chemical constituents of the petroleum ether portion of Nervilia fordii].

Objective: To study the chemical constituents of the petroleum ether portion of Nervilia fordii.

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: Six compounds were isolated and identified as Cyclohomonervilol (I), Octacosanoicacid (II), Stigmasterol (III), Cyclohomonervilol-(E)-p-hydroxy cinnamate (IV), 24(R/alpha)-dihydrocycloeucalenol-(E)-p-hydroxy cinnamate (V), Docosanoic acid (VI).

Conclusion: Compounds I-VI are isolated from this plant for the first time.
