Novel lipid constituents identified from the leaves of Artabotrys odoratissimus (R.Br)

Abstract Novel lipids were isolated from the unsaponifiable matter extracted from leaves of Artabotrys odoratissimus (R.Br) by using n -hexane. The two known compounds, one new carboxyester and two monoesters were the new lipids identified by spectral (IR, 1 H NMR, 13 C NMR spectra, mass spectrum, elemental analysis) and chemical analysis. The carboxyester was identified as 1-carboxy-heneicosane pentadecanoate and two monoesters were identified as hexyl pentaicosanote and pentyl pentaicosanoate. Antimicrobial activities were assessed for all extracts and isolated compounds and showed variable activity. These are novel compounds and being reported first time by us.
