ABSTRACT
The aims of this study are: Firstly, to produce white popinac (L. leucochepala)
seed oil as revealed by the extraction time. Secondly, characterization of white popinac
seed oil in terms of physicochemical propeties, and thirdly, isolation and identification
of the oil chemical composition of white popinac seed oil by GC-MS (Gas
Chromatography-Mass Spectrometry). White popinac seed oil extracted by soxhlet in
different extraction time which are 5, 7, and 9 hours, respectively physicochemical
properties of the oil was tested with SNI 01-3555-1998. Isolation method using
coloumn chromatography and the identification of the oil by the GC-MS.
The results showed that the extraction time had no effect on the moisture and the
saponification value. For the longer time of peroxide value extraction resulted the lower
quality of oil, in the contrary, the longer time of time extraction produced the better
quality of oil. The main compositions of white popinac seed oil are 9-octadecenoate
acid (74,82%), pentadecanoic acid (20,51%) and heptadecanoic acid (4,67%). While the
main composition of the neutral lipid fractions are linoleic acid, ricinoleic acid, and
oleic acid. Glycolipid fractions are composed of linoleic acid, ricinoleic acid and elaidic
acid, and phospholipid fractions are palmitic acid and linoleic acid.
Keywords : Extraction, fractions, L. leucochepala, vegetable oil, white popinac
