Summary: This study evaluated the antioxidant activities of extracts from different parts of traditionally used medicinal plants. The results showed that Euphrasiae stricta and Euphorbia platyphyllos L. had high levels of phenolic and flavonoid compounds and strong free radical scavenging activity. The highest antioxidant activity was observed in Euphrasiae stricta. These findings suggest that these medicinal plants can be used as important antioxidants for treating and inhibiting degenerative diseases caused by oxidative stress.

Summary: The study utilized X-band electron paramagnetic resonance spectroscopy to examine the free radical scavenging activity of various plant infusions, revealing differences in antioxidant interactions and effects of UVA irradiation on these interactions. The tested infusions showed varying abilities to quench free radicals, with UVA radiation reducing antioxidant interactions, particularly for Eupatorium cannabinum L. herb. EPR spectroscopy proved useful for evaluating antioxidant activity of plant infusions, aiding in the search for effective antioxidants for obstetrics applications.

Summary: This article analyzes the impact of anthropogenically transformed environment on the content of pharmaceutically valuable biologically active compounds in medicinal plants. The study focuses on phenolic compounds such as flavonoids, anthocyanins, tannins, and phenolic acids. The discharge of transmissible forms of heavy metals, including cadmium, lead, and mercury, from factories has led to contamination of soil. This affects the activity of enzymes involved in the biosynthesis of phenolic compounds in medicinal plants, resulting in changes in their quantity.

Summary: Exposure to pollutants from industrial development leads to oxidative stress in the human body. Consuming antioxidants through diet has a protective effect against oxidative damage caused by oxidative stress. This study measured the antioxidant activities of certain Nepali medicinal plants and found a strong correlation between the singlet oxygen scavenging capacity assay and other antioxidant assays. Additionally, the antioxidant capacities of the plant extracts, including the singlet oxygen scavenging assay, were highly correlated with their total phenolic contents. The study identified Persicaria capitata, Elaphoglossum marginatum, and Eurya acuminata as having the highest antioxidant capacities among the selected extracts.
