Lipids and triterpenes from Maerua crassifolia growing in Egypt

The hexane fraction obtained from the total alcohol extract of the aerial parts of Maerua crassifolia Forssk grown in Egypt upon repeated column chromatography afforded one new compound identified as 1, 23 dimethoxy tricosa-6-one [1], along with six known compounds identified as long chain hydrocarbon [triacontane] [2], ceryl alcohol [3], lupeol palmitate [4], beta-sitosterol palmitate [5], lupeol acetate [6], and alpha-amyrin [7]. The identification of the isolated compounds was carried out using different physical, chemical and spectral methods and co-chromatography with authentic samples
