Many researchers have shown that plant-derived polyphenolic compounds are helpful nutraceuticals in restraining various disorders such as neoplastic diseases. In this study two linear furanocoumarins, aviprin and aviprin-3″-O-D-glucopyranoside (A3G), were isolated from methanol extract of Prangos
We examined the effects of 48 compounds isolated from Ferula pallida, F. penninervis, Inula macrophylla, Prangos pabularia, P. tschimganica and Rheum maximowiczii collected in Uzbekistan on ADP/Fe2+-induced lipid peroxidation of egg yolk phosphatidylcholine liposomes. Of those compounds, 23
Antioxidant and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities, reducing powers and the amount of total phenolic compounds of aqueous and/or methanolic extracts of some medicinal plants used in Eastern Turkey were studied. These plants are Prangos ferulacea (CASIR), Sedum
Vanillic acid (VA) is a phenolic acid, and acts as a natural antioxidant in fruits, vegetables and plants. The extraction and determination of trace levels of VA in plants is important, because stimulation of protein synthesis and activation of antioxidant enzymes occur in the presence of phenolic
Prangos uloptera DC. (Apiaceae) is indigenous to Iran. It has been used from ancient times for treatment of leukoplakia, digestive disorders and healing scars. In this article, we focus on the various biological screening techniques currently being used to evaluate the biological effects of the
A known furanocoumarin, 8-geranyloxy psoralen, was isolated from n-hexane extract of Prangos uloptera roots by the TLC method. Its structure was determined by comparison of the spectral data with the literature. Cytotoxic effects of the isolated compound were determined by MTT and Tripan blue
Prangos ferulacea (L.) Lindl. (Fam. Apiaceae), is an orophilous species of eastern Mediterranean and western Asia which possesses several biological properties, which are worthy of exploitation in different fields. With the aim to provide new insights into the phytochemistry and pharmacology of this
Purification of extracts from Prangos haussknechtii Bioss afforded prenylated coumarins 1 and 2, monoterpenoid 3, amino acid derivative 4, and seven known compounds. Spectroscopic methods permitted establishment of the structures and relative configuration of these compounds. The pure isolates were
