sea buckthorn berry ; lipophilic and hydrophilic bioactive molecules

Sažetak
Sea buckthorn or sea berry (Hippophae rhamnoides L. ; Elaeagnus rhamnoides L.) (SB) berries contain a wide spectrum of lipophilic and hydrophilic bioactive molecules which possess nutritional and health-promoting properties. Therefore, the aim of this study was to evaluate the content of carotenoids, fatty acids, phenolics, α-tocopherol and L-ascorbic acid in SB berries grown in Croatia. Lipophilic and hydrophilic extracts were obtained by ultrasound-assisted extraction with n-hexane (lipophilic) or 70% ethanol (v/v) (hydrophilic), and analyzed using liquid and gas chromatography. Results showed that analyzed SB extracts were characterized with high content of ascorbic acid (123.89 mg/100 g dw), carotenoids (53.93 mg/100 g dw), flavonoids (50.87 mg/100 g dw) and α-tocopherol (29.85 mg/100 g dw). Moreover, high amounts of unsaturated fatty acids, such as omega-7 palmitoleic fatty acid (34.54%) and omega-6 γ-linolenic acid (10.78%) were also determined. Carotenoids were mainly represented by lutein and zeaxanthin fatty acid esters (35.02 and 15.13 mg/100 g dw), respectively. Among the flavonoids, the most abundant were flavanol glycosides (25.06 mg/100 g dw) such as isorhamnetin-3-hexoside, rutin and isorhamnetin-3-rutinoside. SB berries certainly showed to be a rich source of various antioxidants and they could be used in the production of functional and value added products.
