3-Pentadecylphenol (PDP) is an amphiphilic compound and belongs to a large group of phenolic lipids which is composed of an aromatic headgroup related to phenol or dihydroxybenzene connected to a hydrophobic hydrocarbon chain. PDP is derived from the shell of the cashew nut (Anacardium occidentale L.) which contains oil internationally named “cashew nut shell liquid” (CNSL). PDP can effectively function as an antiobesity agent by inhibiting the activity of α-glucosidase enzyme and finally can regulate body weight in the animal. PDP has also quite promising antioxidant activity. Researchers believe that this compound as an amphiphilic compound should be inserted into the biomembranes and be the antioxidant agent[1]. In particular, phenolic lipids comprise a large group of compounds of natural abundance, which are found in plants, fungi, and bacteria and have different biological functions, like antibacterial, fungicides, and cytotoxic activity[2].
