Abstract
The investigation of the antimicrobial and antioxidant activities of palm kernel oils extracted from varieties Dura (oil D) and Tenera (oil T) of oil palm (Elaeis guineensis Jacq.) and the relationship to their chemical composition were carried out in this study. The results obtained show that oil D had the greatest antimicrobial activity. The analysis of gas chromatographic coupled to mass spectrometry (GC-MS) showed that this oil D contained in addition to the lauric acid, the undecylenic acid which both possess antimicrobial activity. This undecylenic acid was not identified in oil T. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and the Fe3+ reduction test (FRAP) used to evaluate the antioxidant activity of the palm kernel oils had showed that oil T had the greatest antioxidant activity with a concentration inhibiting 50% of the reaction (IC50%) of 750 mg/L. It was also noted that, this oil T had also the highest contents in polyphenols, α-tocopherol and sterols with predominance of β-sitosterol. Moreover, the β-sitosterol is known to possess a regulatory role of the immune system.The findings of this study provide thus, useful information which may help customers to make the best choice in the consumption of these oils.
Highlights
Food and food additives consumed by people are important to improve their immune system which helps them fight against illness (Pegel, 1997) mainly in periods such as this current period of COVID-19 pandemic

Among the vegetable oils used for several purposes since many years ago, there is palm kernel oil derived from the kernel of the fruit of oil palm (Elaeis guineensis Jacq.)
Summary
Food and food additives consumed by people are important to improve their immune system which helps them fight against illness (Pegel, 1997) mainly in periods such as this current period of COVID-19 pandemic. Vegetable oils are an important source of nutrients (presence of essential fatty acids, fat-soluble vitamins, polyphenols, phytosterols) which give them a special role in the diets of populations (Lecerf, 2011) They are extracted from oleaginous plants, which have most of the time, traditionally been used for seasoning and preserving the sanitary quality of foods through the oils they produce (Tchiégang, 2004). The oil extracted from the palm kernel is used in folk medicine for the treatment of skin irritations and mycosis It is used for seasoning the dishes and as a food preservative in Ivory Coast where this oil is abundant and affordable affordable (Yapi & Kouadio, 2019). Despite these characteristics and these uses, there is a lack of studies on the biological activities (antimicrobial and antioxidant activities) of palm kernel oil and on the relationship between these biological activities and the mixture major and minor components of the existing types of palm kernel oil
