Antioxidant Activity of Plantago Species in Vegetative and Flowering Stages
Plantago L. genus (Plantaginaceae) includes a large number of species differing in salt tolerance; many of them are adapted to live in saline environments, thus making the genus Plantago a good model for comparative studies about responses to salinity stress (1). Plantago genus includes species well-known as medicinal plants and others can be used for food and animal feeding (P. coronopus, P. l...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Multigenerational Effects of Flowering and Fruiting Phenology in Plantago Lanceolata
Phenological patterns of flowering and fruiting can be influenced by the effects of reproductive time on seed production. We propose here that these patterns are also influenced by phenological effects on offspring quality. Furthermore, we hypothesize that there are cross-generational trade-offs between parental and offspring components of parental fitness influencing the evolution of reproduct...
متن کاملTotal phenols, flavonoids, anthocyanins, ascorbic acid contents and antioxidant activity of Rhamnus kurdica Boiss for flower and leaves in flowering and pre- flowering stages
The antioxidant capability, total phenol, total flavonoid, anthocyanins, ascorbic acid contents, and reducing power contents of polar and non-polar extracts for flower and leaves in two stages of growth for Rhamnus kurdica Boiss in flowering were evaluated in this work. The polar extraction of flower of R. kurdica Boiss had a higher total phenolic content as well as antioxidant activity compare...
متن کاملEffect of growth stages on total phenolics content and antioxidant activity of Fumaria vaillantii L.
Background and objectives: Plant extracts and their constituents are known to exert biological effects, especially antioxidant activity. Fumaria vaillantii (Fumariaceae) has several therapeutic effects in traditional medicine. Antioxidants are able to protect the human body from oxidative damage connected to the reaction of free radicals. Synthetic antioxidants have to...
