Dormancy and germination requirements were investigated in seeds of Ferula gummosa Boiss (Apiaceae) and Teucrium polium L. (Labiatae). Seeds of both species were subjected to different treatments including various levels of GA3, HNO3, H2SO4, chilling and soaking with water at different temperatures. Germination of both species increased at higher concentrations of GA3. In the case of F. gummosa...

Ferula asafoetida Linn. is a main source of asafoetida, a strong, tenacious and sulfurous odor, and oleo-gum resin of medicinal and nutritional importance. Asafoetida has been consumed as a spice and a folk medicine for centuries. Recent studies have shown several promising activities particularly relaxant, neuroprotective, memory enhancing, digestive enzyme, antioxidant, antispasmodic, hypoten...

Seven new sesquiterpene lactone glycosides (1-7) were isolated from the H2O-soluble fraction from the MeOH extract of the roots of Ferula varia. Their structures were elucidated by extensive spectroscopic analyses. The absolute configurations of compounds 1 and 2 were determined by modified Mosher's method.

Effect of hexane extract of Ferula jaeschkeana has been studied on corpora lutea of adult cyclic guinea-pigs. Administration of extract showed duration dependent luteolytic changes in the corpora lutea. Its administration for first three days from the onset of estrus caused significant decrease in the diameter of corpora lutea in the ovary at day 10 of cycle. Ovarian wet weight, proteins and gl...

dormancy breaking and germination requirements were investigated in seeds of ferula ovina and ferula gummosa. seeds of rather species were collected from north and eastern-north rangelands of iran. seeds of each of the species were subjected to different treatments including various levels of ga3, chilling and combination of ga3 and chilling (ga-chilling). in contrast to treated seeds, non-trea...

Neuroinflammation mediated by microglia cells plays a critical role in the development of Alzheimer's disease. To identify novel natural neuroinflammation inhibitors, a bioactivity-guided phytochemical research was performed on the traditional Chinese medicine "Awei", that exhibited a significant inhibitory effect on nitric oxide production in over-activated microglia cells. The research identi...
