Quercetin is a plant-derived flavonoid widely known by its anti-oxidant and anti-inflammatory properties, but oral bioavailability very poor this becomes difficult to assess therapeutic potential. Here we have compared the effect of quercetin-loaded microemulsion (QU-ME) quercetin suspension (QU-SP) in an experimental model airways allergic inflammation. Mice received daily doses QU-ME (3 or 10mg/kg; oil-in-water content 0.02:0.2:1 lecithin:castor oil:Solutol HS15((R))), QU-SP [10mg/kg,...

A quantitative study was undertaken to assess the plasma and tissue levels, distribution skin (ear) absorption of sesquiterpene α-humulene, main active constituent isolated from plant Cordia verbenacea (Boraginaceae), after oral, intravenous topical administration in mice. The α-humulene levels were quantified by GC-MS analysis. peak concentration achieved 15 min following its oral (150 mg/kg). Then, gradually decreased it almost undetectable at 2 hours 12 administration. When oil C. given...

Tanacetum parthenium (feverfew) is an herb that commercialized worldwide as a therapeutic treatment for migraine. Its pharmacological effect mainly due to the presence of sesquiterpene lactone parthenolide well flavonoids. So far, there are no studies on standardization pre-formulations or phytomedicines containing this herb. The present study aimed at developing pre-formulation using standardized spray-dried extract feverfew and further designing standardizing enteric coated tablets. In...
