Objective:The present study was designed to evaluate the antioxidant, analgesic, and anti-inflammatory activities ofthe methanolic extract of Piper betle leaves (MPBL). Materials and Methods: MPBL was evaluated for anti-inflammatory activity using carrageenan-induced hind paw edema model. Analgesic activity of MPBL was evaluated by hot plate, writhing, and formalin tests. Total phenolic and fla...

Objective: Determination and comparison of the effect of infusion time on the antioxidant activity and total polyphenol contents of bagged and loosely packed black teas. Materials and Methods: For twenty loosely packed and eleven bagged tea samples, the antioxidant activity and total polyphenol content were analyzed using FRAP and Folin-Ciocalteau methods, respectively. The ANOVA with Tukey pos...

with considering importance of post harvest operation on quality criteria of pot marigold (calendula offıcinalis l.), the effect of flower nutrient source (organic inputs such as cattle manure (25 t ha-1), municipal waste compost (20 t ha-1), spent mushroom compost (15 t ha-1), vermicompost (15 t ha-1) and control) as well as different drying methods including microwave (300, 600 and 900 w), ov...

three native turkish medicinal and aromatic plants (artemisia absinthum, artemisia santonicum and saponaria officinalis) were investigated to analyze their antioxidant activity, total phenolic content and antimicrobial activity. their total antioxidant activity was determined by using a β-carotene bleaching assay and their antimicrobial activity was determined by utilizing an agar disc diffusio...

objective: there has been a growing interest in finding plants with biological active ingredients for medicinal application. materials and methods: three colors of petals of althaea officinalis (a. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. results: the reddish pink flowers of a. officinalis have more antioxidant...

The study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of Urtica dioica L. (UD), Malva neglecta Wallr. (MN) plants and their mixture. In this study, flower (UDF), root (UDR), seed (UDS) and leaf (UDL) parts of UD and flower (MNF) and leaf (MNL) parts of MN were used. The antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...
