The methanol extract of the dried aerial parts of Prangos tschimganica gave three new coumarin derivatives and 30 known coumarin derivatives. Their structures were established on the basis of chemical and spectroscopic evidence. Absolute configuration of the isolated compounds were determined by using a modified Mosher's method. Some of the isolated compounds showed anti-HIV activity.

BACKGROUND AND OBJECTIVE: The genus Prangos is among plants with numerous species. The positive medicinal effects of this herb have been demonstrated in multiple studies. The aim of this study was to evaluate the effects of methanolic extracts from Prangos uloptera and crossoptera on the growth and proliferation of human lymphocytes and determine their mutagenic potentials. METHODS: In this exp...

Several species of Prangos are traditionally used as emollient, carminative, tonic, anti-flatulent, anthelmintic and anti-thrombotic agents. Osthole, a coumarin isolated from Prangos, are believed to be responsible for some of its effects. In this research, relaxant effects of Prangos ferulacea extract and osthole on rat uterus contraction induced by KCl, acetylcholine (ACh), oxytocin and elect...

Background The present study was conducted on the effect of prangos ferulacea vaginal cream on accelerating the recovery of bacterial vaginosis. Methods This randomized controlled clinical trial was conducted on 100 non-pregnant women referring to health centers affiliated to Lorestan University of Medical Sciences in 2016 with the diagnosis of bacterial vaginosis based on the patient's compl...

The dichloromethane extract of the roots of Prangos hulusii, a recently described endemic species from Turkey, has yielded nine known and one new prenylated coumarins. The structures were elucidated by spectroscopic methods and direct comparison with the reference compounds where available. The root extract and its prenylated coumarins exhibit antimicrobial activity against nine standard and si...

Phytochemical analysis of the dichloromethane:methanol (1:1) extract of root parts of Prangos pabularia led to the isolation of twelve cytotoxic constituents, viz., 6-hydroxycoumarin (1), 7-hydroxycoumarin (2), heraclenol-glycoside (3), xanthotoxol (4), heraclenol (5), oxypeucedanin hydrate (6), 8-((3,3-dimethyloxiran-2-yl)methyl)-7-methoxy-2H-chromen-2-one (7), oxypeucedanin hydrate monoacetat...
