Special Issue Information

Dear Colleagues,

Oil plants make up an important part of the world's cultivated plants. They are a source of oil, not only for nutritional but also for cosmetic and medical applications. Vegetable oils, as an excellent source of polyunsaturated fatty acids, are an important element of a healthy diet and a factor in the prevention of such civilization diseases as diabetes, atherosclerosis or cardiovascular diseases. Despite the undeniable beneficial effect of such products (oils) on our health, the optimal use of their properties still requires a lot of research. The substances of antioxidant character present in the oil should be of particular interest—they not only affect its properties and stability but can be an additional value in biomedical applications. One should also not forget about the possibility of obtaining beneficial substances from the remains of the oil obtained (pomace, seedcake, etc.). This way of thinking fits in with the philosophy of zero waste, which is incredibly good for our planet.

This Special issue should include all research carried out on oil plants aimed at better understanding the properties of these plants, their products, and the technology of obtaining and processing health-promoting preparations based on these plants. The presented work presents biochemical analyses of plant products, modifications leading to the acquisition or production of more efficient/compositionally better/more stable/richer in antioxidants oils or other oil plant products. The technologies using byproducts considered to be waste products of oil production may be interesting. An interesting section will also be plants that produce essential oils and the use of these oils in medicine, cosmetics, and food.

Preclinical studies or studies on the effect of oil-based products on mammalian cells are also welcome. 

A separate issue is the issues related to disease prevention and the use of oils as dietary supplements or dietary supplement for various disease entities.

Rose hips are the fruits of the beach rose (Rosa rugosa). To determine the optimal harvest time and to obtain the maximum functional compounds, rose hips at various stages of ripeness (immature, early, mid, and late) were harvested, and the flesh tissue and seeds were separated. The rose hip flesh showed the highest total phenolic content at the mid-ripeness stage (8.45 ± 0.62 mg/g gallic acid equivalent concentration (dry weight)). The early-, mid-, and late-ripeness stages of rose hip flesh did not show significantly different 2,2-diphenyl-1-picrylhydrazyl antioxidant capacities. The elastase inhibitory activity of the 95% ethanol extract from the rose hip seeds was highest at the mid-ripeness stage; however, the elastase inhibitory activity of the rose hip tissue was not significantly different from that of the seeds. Pathway analysis using MetaboAnalyst showed that sucrose, fructose, and glucose gradually increased as the fruit ripened. Ursolic acid was detected in the seeds but not in the flesh. Of the fatty acids, linoleic acid concentrations were highest in rose hip seeds, followed by linolenic acid, oleic acid, and palmitic acid. Fatty acids and ursolic acid might be the active compounds responsible for elastase inhibitory activity and can be utilized as a functional cosmetic material. Full article
