Dietary Supplementation with Raspberry Seed Oil Modulates Liver Functions, Inflammatory State, and Lipid Metabolism in Rats

Abstract

Dietary RO improves plasma lipid profile and liver functions and reduces low-grade systemic inflammation in rats; however, the extent of these beneficial effects is partly dependent on the diet type.

Oils from fruit seeds and their dietetic and cosmetic significance

“…The Latin name of this plant refers to the red colour (Rubus) and the Ida mountain in Crete, where raspberries come from and where they grow nowadays too [21]. Raspberry seeds contain about 23% oil, which is a source of saturated (palmitic (2.1%), stearic (0.9%)) and unsaturated (alpha-linolenic (23.9%), linoleic (57.5%), oleic (13.3%), eicosenic (0.4%)) fatty acids [1,9,24]. Among the mentioned bioactive components, there are polyphenol compounds (2.65 mg·100 g -1 ), phytosterols (5.38 mg·g -1 ) including campesterol, stigmasterol, sitosterol, avenasterol, cytrostadienol, and carotenoids including zeaxanthin, β-carotene, lutein and cryptoxanthin [9,22].…”

“…Raspberry seed oil also contains large amounts of vitamin E (301.9 mg·100g -1 ); tocopherols (295.19 mg·100 g -1 ), including α-tocopherol (71 mg·100 g -1 ), γ-tocopherol (272 mg·100g -1 ), Δ-tocopherol (17.4 mg·100 g -1 ); and tocotrienols (6.73 mg·100 g -1 ) [9,23]. Consumption of raspberry fruit has been associated with a decrease in the risk of developing many chronic diseases, such as obesity and cardiovascular diseases [24]. Due to the content of active substances and specific biological properties, raspberry seed oil can be used as a nutraceutical.…”

“…Due to the content of active substances and specific biological properties, raspberry seed oil can be used as a nutraceutical. This oil is appreciated as a component of the diet, being a source of essential fatty acids and preventing the development of diseases of civilisation [9,24]. It has been shown that raspberry seed oil can affect the improvement of liver function [24].…”

“…This oil is appreciated as a component of the diet, being a source of essential fatty acids and preventing the development of diseases of civilisation [9,24]. It has been shown that raspberry seed oil can affect the improvement of liver function [24]. Pieszka et al [9] prove that raspberry seed oil used as a food supplement has strong antioxidant properties.…”

“…It was confirmed that raspberry seed oil can be a well-tolerated base for cosmetics and dermocosmetics, not causing skin irritation. Research by Pereira et al [25] shows that the nano-emulsion based in plant oils (raspberry, passion fruit and peach oil) positively influences the condition of the skin, improves hydration and lubrication, without changing the pH value of the skin [24]. Oomah et al [23] report that raspberry seed oil has the ability to absorb UV radiation, thus it can be used and consequently a deficiency in the body of these acids (ω-3).…”
