coumarins are bioactive secondary metabolites and could be found in the fruits of umbelliferae. prangos asperula boiss. is an iranian native plant which is found wild in many regions of iran. osthol, a prenylated coumarin, was isolated from the hexane extract of the fruits of p. asperula and its structure was elucidated using 1 hnmr, 13 cnmr, ir and ms spectra. the essential oil of the aerial p...

Leishmaniasis has a wide spectrum of signs and symptoms due to infection to numbers of Leishmania species and makes enormous mortality and morbidity. There are clues of antileishmanial effects of prenylated coumarins. Apiaceae family is one of the most important sources of coumarins. Air-dried aerial parts of Ferulago angulata and fruits of Prangos asperula were extracted with n-hexane, using a...

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...
