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

ABSTRACT

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.
