The main objective of this research is to identify qualitatively the different classes of organic compounds in local peanuts. Three varieties of peanuts; Bandau Triplets, Kacang Raja and MGNT VI which obtained from Tuaran Agriculture Research Centre are as the sample in this analysis. Since the main components of peanuts are lipids, therefore lipids determination on peanuts is interested in this research. Total lipids in peanuts are determined quantitatively by using Soxhlet method while sterols in peanuts are identified qualitatively by using thin layer chromatography silica gel 60 HF254. Phytochemical tests is carried out to test the present of alkaloids, flavonoids, saponin, tannins, anthraquinone and phenolic compounds in the peanuts sample. Alkaloids, flavonoids, saponins and phenolic compounds are present in three of the peanut samples while tannins and anthraquinone are absent in the sample. The highest total lipids yield is Kacang Raja follow by Bandau Triplets and MGNT VI. In the TLC sheets, the compound is in Rf 0.11 and qualitatively identified as sterol compounds. The developing solvent system in the TLC that manages to well separate the compounds is hexane: diethyl ether: methanol with the ratio 25:25:50.
