Studies have demonstrated that phenolic compounds andcarotenoids are essential for prevention of diseases. On the other hand, endogenous ethylene enhances the ripening of fruits and stimulatesthe biosynthesis of carotenoids as well as chlorophylls destruction. The aim of this study was to evaluate the effect of rootstocks on phenolic compounds andcarotenoids. The contents of individual phenolic...

Sunflower (Helianthus annuus L.) is largely consumed in Iran as an oleaginous and confectionery product. In this study, the total phenolic and flavonoid contents, antioxidant activity and phenolic composition in different parts of the seeds from six sunflower genotypes were investigated. The antioxidant activity of extract was evaluated by different assays. The total phenolic and flavonoid cont...

This study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (Prunus dulcis)kernel. Raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (pH 5.0) and 0.02 mol dm-3 phosphate buffer solution (pH 7.0) at 25 and 40ºC, respectivel...

objective: the present study was conducted to detect possible chemicals (phytoconstituents), prove ethno-medicinal value of the plant, and investigate antimicrobial, anthelmintic, and total phenolic content of crude methanolic extract of the solanum violaceum plant.  materials and methods: phytochemical screening was carried out using different chemical group test methods. in anthelmintic activ...

Ruta species are known as a potential source of natural products with biological activities. They are used in several fields such as in therapeutic and traditional medicine. In order to contribute to the valorization of these plants, this work investigated the chemical composition and antibacterial activity of the essential oils of Ruta montana and Ruta gravelons growing in tunisia (north o...

In the current study, we investigated 2 species of the genus Rhodiola for the inhibition of alpha-amylase,alpha-glucosidase and angiotensin converting enzyme (ACE) inhibitory activity. Water extracts of Rhodiola crenulata had the highest alpha-amylase inhibitory activity (IC50,98.1 microg total phenolic /ml) followed by ethanol extract of R.crenulata (IC50, 120.9 microg total phenolic/ml) and e...

Woodland sage (Salvia nemorosa) is an important native medicinal plant in Iran and is considered as a rich source of phenolic and flavonoids compounds. The present research was conducted with respect to the optimization of medium for biomass accumulation and secondary metabolite production in cell suspension culture of S. nemorosa. In this research the effects of total nitrogen content (0, 15, ...
