Abstract

BRANCO, Alexsandro  and  PIZZOLATTI, Moacir G.. HRGC and HRGC-MS in the analysis of the chemical constituents isolated from hexanic extract of Sebastiania argutidens (Euphorbiaceae). Quím. Nova [online]. 2002, vol.25, n.1, pp.15-19. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422002000100004.

The fractionation column with SiO2 of the hexane extract of Sebastiania argutidens (Euphorbiaceae) yielded fractions containing hydrocarbons, carboxylic acids, sterols and pentacyclic triterpenes. Besides, one fraction showed the presence of several methyl esters, including four uncommon long chain palmitate esthers as minor components. The characterization of these chemical constituents have been done by High Resolution Gas Chromatography (HRGC) and HRGC coupled to Mass Spectrometry (GC/MS). Campesterol, stigmasterol, b-sitosterol, glutin-5-en-3-ol were identified by HRGC co-injection with standards.

Keywords : Sebastiania argutidens; triterpenes; HRGC-MS.
