Abstract
Samrong (Sterculia foetida Linn.) is a wild plant. It is used in traditional medicine. The kernels of samrong seeds have been reported to contain a high amount of oil. The changes in fatty acid profile, volatile compounds, and fourier transform infrared (FTIR) spectra of oil from samrong seed kernel during storage (48 days) were investigated. With increasing storage time, the content of saturated fatty acid (SFA) and polyunsaturated fatty acid (PUFA) decreased. There was little change in fatty acid profile at the end of storage. As to FTIR spectra, a slight change in wave number from 3600 cm-1 to 3200 cm-1 and wave number 1711 cm-1 was observed with increasing storage time. After storage, the results observed 12 volatile lipid oxidation compounds. However, slight changes in abundance of volatile compounds were found. Therefore, samrong seed kernel oil had good oxidative stability.
