AIM: To study the chemical constituents of the stem part of Ichnocarpus frutescens. METHODS: The ethanolic extract of Ichnocarpus frutescens was used for the isolation of chemical constituents with the help of silica gel G and Sephadex column chromatography and their structures were elucidated on the basis of spectral data and chemical methods. RESULTS: Five compounds were isolated and identified as n-butyl oleate (1), n-octyl tetracontane (2), tetratriacontadiene (3), n-nonadecanyl benzoate (4), and benzocosanyl arachidate (5). CONCLUSION: Compound 5 is new; and compounds 1-4 are isolated from genus Ichnocarpus frutescens for the first time.
