Sea buckthorn (Hippophae rhamnoides L., Elaeagnaceae.) is a thorny shrub that has small, yellow to dark orange, soft, juicy berries. Due to hydrophilic and lipophilic ingredients, berries have been used as food and medicine. Sea buckthorn (SB) oil derived from berries is a source of valuable ingredients for cosmeceuticals. The unique combination of SB oil ingredients, in qualitative and quantitative aspects, provides multiple benefits of SB oil for internal and external use. Externally, SB oil can be applied in both healthy and damaged skin (burns or skin damage of different etiology), as it has good wound healing properties. Due to the well-balanced content of fatty acids, carotenoids, and vitamins, SB oil may be incorporated in cosmeceuticals for dry, flaky, burned, irritated, or rapidly ageing skin. There have been more than 100 ingredients identified in SB oil, some of which are rare in the plant kingdom (e.g., the ratio of palmitoleic to γ-linolenic acid). This review discusses facts related to the origin and properties of SB oil that make it suitable for cosmeceutical formulation.

In the present study, a coffee-like beverage was prepared from Quercus cerris seeds.

The aim of this study was to investigate in vitro antioxidant and antimicrobial potential of methanol and chloroform extracts of Sanguisorba minor L. subsp. muricata Briq. herba. Total phenolic and flavonoid content of the investigated extracts were characterized. Antioxidant activity was estimated by five different in vitro assays. Antioxidant potency composite index was calculated also. Antimicrobial activity was tested against nine bacterial and one fungus strains by the micro-well dilution assay. The methanol extract of S. minor contains more phenols and shows the stronger antioxidant and antibacterial activity in comparison to the chloroform extract. However, the chloroform extract was superior to the methanol extract in content of flavonoids. Gram-positive bacteria were more sensitive than Gram-negative, to both extracts, Staphylococcus aureus being the most sensitive. Sanguisorba minor extracts were not considerably active against Candida albi-cans. The previous research data about Sanguisorba minor are scarce, so this data represent the first report on antimicrobial activity of S. minor. These results indicate that extracts of S. minor subsp. muricata have evidence-based potential for more comprehensive studies.
