This paper reports on the effect of captopril on the stability of unsaturated fatty acids in the evening primrose oil. The experiment was performed for captopril at concentrations of 0.05%, 0.1% and 0.2% in the samples of evening primrose oil at temperatures of 20 degrees, 40 degrees and 60 degrees C. The determination was performed on the 10th day of incubation. The results were compared to those obtained for analogous samples with octyl gallate, an antioxidant commonly used in oil systems, taken at the same concentrations and at the same temperatures. The changes in concentrations of the substances studied with time were monitored by gas chromatography. The results have shown captopril to be a stronger antioxidant than octyl gallate at all concentrations and temperatures used.

There is a growing need for safer alternatives to synthetic additives commonly used in lipophilic carriers for products such as foods, pharmaceuticals, personal care items, and cosmetics. Natural antioxidants, which prevent lipid peroxidation while providing additional health benefits, offer a promising solution. Evening primrose oil, a rich source of antioxidant compounds with numerous biological benefits, emerges as a potential natural preservative for oil-based products.

This study aimed to evaluate the oxidative stability and surface properties of cold-pressed vegetable oils using the Langmuir monolayer technique. Six oils-milk thistle, evening primrose, flaxseed, camelina sativa, black cumin, and pumpkin seed-were analyzed to investigate their molecular organization and behavior at the air/water interface, particularly after undergoing oxidation. The results showed that oils rich in polyunsaturated fatty acids (PUFAs), such as flaxseed and evening primrose oils, formed monolayers with larger molecular areas and lower stability, which led to faster oxidative degradation, especially under thermal conditions.

The pathogenesis of atopic dermatitis (AD) points to skin barrier dysfunction as a critical piece of the puzzle. Deficiencies in fatty acids and ceramides-key elements of the skin barrier-have been linked to AD. Fatty acids can be separated into omega-3 and omega-6, which can be found in a variety of foods such as fish, nuts, seeds, and even plants.

Chronic pruritus, or persistent itching, is a debilitating condition that severely impacts quality of life, especially in palliative care settings. Traditional treatments often fail to provide adequate relief or are associated with significant side effects, prompting interest in alternative therapies. This review investigates the antipruritic potential of eight medicinal plants: chamomile (), aloe vera (), calendula (), curcumin (), lavender (), licorice (), peppermint (), and evening primrose ().
