Oils are subjected to many changes. Oxidation results in changing oils characteristics and producing harmful effects in human body that affected on lipids profiles so increase the risk of cardiovascular diseases. Synthetic antioxidants are added to reduce the changes but many researchers have proved the side effects of these synthetic chemicals. So it is important to replace these artificial antioxidants with natural one to protect human health.
The biological evaluation of the cottonseed oil with the added essential oils (thyme, cinnamon and peppermint oils) in rats diets 42 days to indicate its effect on rats’ serum lipids was carried out.  Determination of major constituents in essential oils by GC-Mass spectrometry.
The results revealed that the superiority of the essential oils over the control, heated and TBHQ reduce total lipids, total cholesterol, and atherogenic factor. On the other hand it was obvious that the addition of TBHQ or using the heated oil only without any additions had inferior effects on blood lipid picture compared to the natural essential oils. The chromatographic analysis results showed that essential oils contain active major chemicals that are responsible for the effect of these essential oils. It was found that thymol and p-Cymene are the major constituents of thyme oil 52% and 31%, respectively. Also, cinnamaldehyde was 72% in cinnamon oil, while menthol was 65% in peppermint oil.
It could be concluded that adding essential oils improves the blood lipid in most cases so it can be used as natural antioxidants. Further researches are need on the effects of adding essential oils.
