【 摘 要 】

The main objective of the current work was to investigate the unknown compound composition contains in Leucaena Leucocephala (Petai Belalang) to prove that there were antioxidants properties presents in the leaves and seeds of the plant. High-performance liquid chromatography (HPLC) and Fourier-transform infrared spectroscopy (FTIR) were used to characterize the samples. It was found that for both leaves and seeds sample of Leucaena Leucocephala, the spectrum had shown the main existence of alcohol (O-H bond. As the O-H bond is the main element of antioxidant and phenolic compound, the FTIR analysis shows for the high possibilities for the present of antioxidant and phenolic compound in the leaves and seeds of Leucaena Leucocephala. Further analysis using HPLC, both seed and leaf sample shows for the presence of the same compounds, identified as apigenin, caffeic acid, formic acid, isorhamnetin, keampferol, luteolin and quercetin, but by comparing the peak, can be concluded that the compounds in seed are higher than the compounds in leaf.
