“…Recently, there is an increasing interest for unconventional oilseeds, such as prunus seeds, due to their valuable functional constituents with significant biological activities 1) . Among prunus species, Prunus persica kernels are an important by-product of the fruit processing industry which contain about 32 -45％ of non conventional oil.…”

“…So, in order to improve the studies on peach oil, more attention should be paid to its minor components and their biological proprieties. Unconventional oils are of vital dietary and economic importance now and in future, therefore it seems necessary to gather more data and build up sufficient knowledge of missed information for many unconventional oilseed s sources 1) . Peach kernels are currently underexploited and different studies are being conducted to recover possible bioactive compounds from them in order to prevent economic losses and environmental pollution 3) .…”

for edible and other industrial applications 5) . In fact, growing population of the world leads to the higher demand for edible oils which required introduction of alternative unconventional sources of vegetables oils 1) . Currently, the focus of the food industry is to recover and exploited the valuable by-products from agricultural waste biomass 6) .Triacylglycerols are the major components of vegetable oils (95-98％) , while phospholipids, phenolic compounds and unsaponifiable lipids such as sterols, tocochromanols and n-alkanes are the minor components. Other than health benefits, the minor constituents of vegetable oils determine the quality of the oil and provide a valuable marker for oil authentication 7,8) . The n-alkane profile could be used to distinguish between different vegetable oils and recent method has been developed for the determination of these minor compounds 9) . Therefore, the n-alkane com-Abstract: Although peach kernels are rich in oil, there is a lack of information about its chemical and biological properties. Therefore, the purpose of this study was to determine the lipid profile, antioxidant capacity, and trypsin inhibitory propriety of peach oil extracted from two varieties (sweet cap and O'Henry) cultivated in Tunisia. The investigated peach kernel oil contains significant amount of unsaponifiable (2.1±0.5-2.8±0.2% of oil) and phenolic compounds (45.8±0.92-74.6±1.3 mg GAE/g of oil). Its n-alkane profile was characterized by the predominance of tetracosane n-C24 (47.24%) followed by tricosane n-C23 (34.43%). An important total tocopherol content (1192.83±3.1 mg/kg oil) has been found in sweet cap cultivar. Although rich in polyphenols and tocopherols, the tested oil did not display an inhibitory effect on trypsin. However, all peach oil samples showed effective antioxidant capacity and the highest values (86.34±1.3% and 603.50±2.6 μmol TE/g oil for DPPH test and ORAC assay, respectively) were observed for sweet cap oil. Peach oil has an excellent potential for application in the food and pharmaceutical industries as source of naturally-occurring bioactive substances.
