ABSTRACT
Shorea sumatrana is one of Indonesian endemic plants easily found in
Jambi Province. Other name of this plant are Meranti Kuning and
Tengkawang. This species can be used as source of Tengkawang oil by
using hot pressure method. Nonpolar fraction of the fruit seed of
Shorea sumatrana has antioxidant activity. Tengkawang still has better
future to be develop. The aim of this research to study fat seed oil of
Tengkawang a endemic plant from Indonesia. The research method
consisted of qualitative test using Gass Chromatography – Mass
Spectroscopy (GC-MS) and grain seed quality. GC-MS test results
from tengkawang seeds oil showed that it contains Boric Acid 32,48%,
Cyclotrisiloxane 1,96%, Hexadecanoic acid 18,51%, 9,12-
Octadecadienoic acid (Z, Z) - 16,19%, 9-Octadecenoic acid (Z) -
19,73%, - Octadecenoic acid 3.77%, and Octadecanoic acid 7.35%.
Fatty acid test results showed acid number as much as 13,7925 mg KOH/g, saponification
number 168,4779 mg KOH/g, and peroxide number 20,4775 mg KOH/g
Keywords: Shorea sumatrana, GC-MS, Tengkawang, Endemic Plant.
