Assessment of antioxidant and antimicrobial activities of Crambe spp. during vegetation.

Background: The search for new plant raw material as a potential source of antioxidants is still ongoing. This study aimed to evaluate the antioxidant and antimicrobial capacity of the plant raw material of Crambe spp. during vegetation.

Biological properties of sea buckthorn (Hippophae rhamnoides L.) derived products.

Background: Sea buckthorn is a good and possible source of a wide range of bioactive compounds with     a positive effect on the human body, especially polyphenols and carotenoids.

Methods: The present study aimed to evaluate the antioxidant and antimicrobial activities of Hippophae rhamnoides L. products - 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs).

Evaluation of the antioxidant activity and phenolic content of Chinese quince (Pseudocydonia sinensisSchneid.) fruit.

Background: Neglected and underutilized plant species could serve as a valuable source of natural bioactive compounds. The objective of this study was to evaluate the biological activity of Chinese quince (Pseudocydonia sinensis Schneid) genotypes of Ukrainian and Slovak origin.

Methods: The content of the total antioxidant activity (DPPH method and molybdenum reducing antioxidant power), total polyphenol, flavonoid and phenolic acid compounds in the pulp and peel of Chinese quince were compared across five genotypes from Slovakia and three from Ukraine.

Antioxidant activities and phenolic compounds in fruits of various genotypes of American persimmon (Diospyros virginiana L.).

Background: American persimmons (Diospyros virginiana L.) are known as a widespread cultivar which were traditionally used by Native Americans as a food source, and since ancient times have been used in folk medicine. The objective of this study was to evaluate the antioxidant activity and phenolic content of Diospyros virginiana genotypes.
