(black elder) as a traditional medicine have been associated with the phytoconstituents including polyphenols, terpenes and lectins. Various antioxidant rich natural products have also been implicated with improvement of reproductive health and fertility, however, the effect of Sambucus nigra on the ovarian cell functions has not been investigated yet.

- - The study evaluated the antioxidant properties of various cultivars of Capsicum, specifically Capsicum annuum, C. baccatum, and C. chinense, measuring factors like free radical scavenging activity and total polyphenol content.
- - Results showed significant variations in antioxidant activity among the different cultivars, with C. baccatum cultivar 07 exhibiting the highest molybdenum reducing power and total polyphenol content.
- - Strong correlations were found between total polyphenols and other antioxidant measures, suggesting that higher polyphenol content likely enhances the antioxidant capacity of these pepper cultivars.
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.
Quercetin is a dietary bioflavonoid used widely as a food supplement and is generally recognized as safe. The aim of this study was to examine the steroid hormone (progesterone and 17- β estradiol) release, proliferation (PCNA and cyclin B1) and apoptosis (caspase 3 and p53) of porcine ovarian granulosa cells after the addition of quercetin at concentrations 0.01, 0.
