In Iranian traditional medicine, there are some report regarding the anticonvulsant effect of Ferula gummosa Boiss. In this study, anticonvulsant activity, neurological deficits and lethality of the root acetone extract of this plant were evaluated in mice. The extract exhibited dose-dependent prevention of tonic seizures induced by pentylenetetrazole (ED50 = 154.4 mg/kg). However, the extract ...

From the dichloromethane extract of aerial parts of Ferula vesceritensis (Apiaceae), 11 sesquiterpene derivatives were isolated. Among them five were compounds designated as 10-hydroxylancerodiol-6-anisate, 2,10-diacetyl-8-hydroxyferutriol-6-anisate, 10-hydroxylancerodiol-6-benzoate, vesceritenone and epoxy-vesceritenol. The six known compounds were identified as feselol, farnesiferol A, lapido...

Dormancy and germination response of Galbanum seeds (Ferula gummosa) under different hormonal pre-treatments cold stratification

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...
