In generally, bioactive compounds are named functional compounds. There is trend to investigate of isolation, identification and biological activities of functional compounds from natural sourcs in recent years. The aim of this work is to investigate functional compounds analysis and their antioxidant capacity of cherry laurel seed. In this work some functional compounds were isolated by chromatographic techniques and identification of their structure by spectroscopic (NMR, IR, UV, etc.) methods. Amygdalin, prunasin, and β-sitosterol compounds were isolated. These compounds firstly were isolated from cherry laurel seed. The antioxidant capacities of these compounds have been investigated with some different antioxidant methods. In this study, it has been shown that reduction power activities of these compounds were higher than BHA and lower than BHT and α-tocopherol.
