This study was aimed to extract and to isolate some bioactive compounds present in the stems of Pergularia tomentosa L. The Phytochemical analysis of the stems extracts showed that this plant is rich of various secondary metabolites such as alkaloids, flavonoids, saponins, steroids, tannins etc. Five extracts were obtained using different solvents...

In this study we used spectrophotometrical techniques to estimate antioxidant efficacy by using 2,2-diphenyl-1-picrylhydrazyl free radical scavenging capacity and reducing power capacity. We have used also electrochemical techniques performed by cyclic voltammetry. The present study examined the antioxidant activities of the methanolic extract (ME)...

ABSTRACT Phytochemical compounds are known to be components of many plants and herbs; they have received great interest from the public and scientists due to their health benefits as antioxidants. The aim of the present study was to reveal the bioactive compounds and evaluation of antioxidant activity of the ethyl acetate, n-butanol extracts of Ast...

A new megastigman sulfate (1) was isolated from the aerial part of Zygophyllum gaetulum. The structure of 1 was elucidated as (E)-3-sulfooxymegastigm-7-en-9-one by analysis of spectroscopic data. In addition, 22 known compounds were isolated. Triterpenoid saponins 3, 4, 5, 7, 9, 12, and 13, and compounds 17–23 were isolated from Z. gaetulum for the...
