Abstract
4-Desmethylsterols of sterol glycoside (SG) of oil palm leaves were separated and analyzed by GLC on both OV-1 (0.5 μm) and OV-17 (0.25 μm) capillary columns of the same size (25m×0.25mm i. d) under the same conditions. The extent of separation of each 4-desmethylsterol of SG was essentially the same on both columns. Campesterol, stigmasterrol, sitosterol, 7-stigmastenol and avenasterol were found, in addition to a traces of cholesterol and brassicasterol. The compositions of these sterols by the OV-17 column were 4.8, 8. 9, 84.2, 1.1, and 1.0 %, respectively.
