The use of plants to treat skin ailments has strong support in the current trend of drug discovery. Propionibacterium acnes, an anaerobic pathogen, plays an important role in the occurrence of acne. The present study was conducted to evaluate the antimicrobial and antioxidant activities against P. acnes and cytotoxic effects of 48 medicinal plants grown in South Africa. The broth dilution and D...

The current study was assigned to evaluate the total phenol, total flavonoid content (TPC, TFC) and antioxidant properties of extracts from the aerial parts of Scrophularia frigida (S. frigida). Extracts were also tested by preliminary phytochemical screening as well as cytotoxic activity against Artemia salina, MCF-7 (human breast carcinoma) and SW-480 (colon carcinoma) and L-929 (normal) cell...

background: many members of the genus satureja l. (lamiaceae) have interesting pharmacological and biological properties. objective: in this research, major essential oil (eo) compositions, rosmarinic acid (ra) content, and antioxidant and antibacterial properties of the leaf extracts of nine satureja species (s. bachtiarica, s. mutica, s. sahandica, s. macrantha, s. atropatana, s. edmondi, s. ...

The roots of Salvia miltiorrhiza are widely used in traditional Chinese medicine. In our study we investigated the effects of brassinosteroid on drought resistance in S. miltiorrhiza using the method of measuring the antioxidant enzyme activity (SOD, CAT, POD) of S. miltiorrhiza seedling under drought stress after spaying different levels of brassinosteroid. The results showed that after sprayi...

The plants of the genus Salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. Eleven Salvia species including S. aegyptiaca, S. aethiopis, S. atropatana, S. eremophila, S. hypoleuca, S. limbata, S. nemorosa, S. santolinifolia, S. sclarea, S. syriaca, and S. xanthocheila ...

The purpose of this study was to examine the association of vitamin B6 status and plasma homocysteine with oxidative stress and antioxidant capacities in welders. Workers were divided into either the welding exposure group (n = 57) or the nonexposure controls (n = 42) based on whether they were employed as welders. There were no significant differences in vitamin B₆ status and plasma homocystei...

Exercise increases metabolic rate and the production of reactive oxygen species (ROS) but also elevates protein turnover. ROS cause damage to macromolecules (e.g., proteins) and thereby contribute to aging. Protein turnover removes and replaces damaged proteins. The balance between these two responses may underlie beneficial effects of physical activity on aging. Effects of lifelong exercise on...

Natural products can be a source of biomolecules with antioxidant activity which are able to prevent oxidative stress-induced diseases and show antitumor activity, making them important sources of new anticancer drug prototypes. In this context, this study aimed to analyze the chemical composition of an ethanol extract of Senna velutina leaves and to assess its antioxidant and cytotoxic activit...

Nowadays, phytochemicals and antioxidants in plants are raising interest in consumers for their roles in the maintenance of human health. Phenolics and flavonoids are known for their health-promoting properties due to protective effects against cardiovascular disease, cancers and other disease. Ginger (Zingiber officinale) is one of the traditional folk medicinal plants and it is widely used in...
