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

To study the chemical constituents of the petroleum ether portion of Nervilia fordii. The constituents were separated and purified by using column chromatography with silica gel. These compounds were identified by their physical and spectral data. 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). Compounds I-VI are isolated from this plant for the first time.
