Prangos ferulacea is a plant found in the Mediterranean and Middle-east regions used as carminative, anti-flatulent, emollient and antibacterial herb. It is believed that the coumarins are responsible for some of known effects of Prangos. In this research the relaxant effects of P. ferulacea coumrin rich extract as well as osthole as its main prenylated coumarins were investigated on rat ileum ...

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...

dendrobium genus was reported to contain alkaloid, bibenzyl, fluorenone, phenanthrene, sesquiterpenoid, and phenolic acid, which have biological properties. our aim was to investigate the protective effect of an aqueous extract of dendrobium nobile lindl (dne) against cisplatin-induced acute kidney injury (aki). quantification of four phenolic acids (4-hydroxybenzoic, vanillic, syringic, and fe...

The Influence of Competition on some Structural Features Persian Oak (Quercus brantii Lindl var.persica) Trees in Zagros Forest (Case study:Hashtad- Pahlu,Lorestan)

In vitro asymbiotic seed germination of Dendrobium chrysotoxum varied with fruit harvesting time and culture medium used for germinating seeds. Seeds at different developmental stages were harvested and cultured on five asymbiotic orchid seed germination media i.e. defined and undefined media, namely 1⁄2 MS, KC, M, MS and PDA. Seeds harvested 220 days after pollination showed maximum germinatio...

Inhibition of the cell growth or induction of cell death is the most promising area in cancer therapy. The induction of apoptosis by dichloromethane extract of Prangos uloptera was evaluated on the McCoy cell line. This plant's roots, aerial parts and fruit have medicinal value. Cell growth inhibitory and cell cytotoxicity effects of the extract were assayed by MTT and Trypan-blue tests, respec...
