Abstract
L-Dopa has been shown to be an effective drug for the treatment of Parkinson’s disease. Synthetic L-Dopa is relatively expensive and some side-effects have been reported associated with artificial products. Fava beans is known as a rich natural sources of L-Dopa and clinical studies have shown that its anti-Parkinson’s characteristics has no or minimal side-effects compared with synthetic forms. Concentration of L-Dopa is often measured in seeds while other parts of plants may accumulate significant amounts of this chemical. The accumulation of L-Dopa in different plant organs of fava beans was studied in the field and controlled environment. In Field condition Windsor which is currently the common fava beans variety used in New England was planted on April 2013. Fava beans were harvested at six-leaf stage and when pods were fully grown. Plant parts were digested separately and analyzed for L-Dopa concentrationusing HPLC. The contents of L-Dopa in plant parts werein the following order; seedlings> leaves > terminal buds > seeds > roots > stems with 13.3, 10.5, 9.5, 7.2, 6.5, 3.5 mg g-1, respectively. Accumulation of L-Dopa from germination until 10-leaf stage in eight varieties of fava beans was studied in greenhouse. All varieties had their peak concentration of L-Dopa between 2-4 leaf stages followed by a declining trend. Delle Cascineand Bell bean varieties had the most and the least concentrations of L-Dopa by 10.89and 7.56 mg g-1respectively.Also, accumulation of L-Dopa after applying drought stress on Windsor variety was studied. The results indicated that drought stress did not influence L-Dopa concentration at various stages of growth. L-Dopa concentration in 6-leaf stage was higher than other stages of growth (20.1 mg/g) when affected by severdrought stress.

Abstract
The present study was designed to investigate the potential of Coleus forskohlii plant extract- ‘forskolin’ in experimental dementia in wistar rats. Dementia was induced by the administration of high fat diet (HFD) for 90 days. The effects on learning and memory were assessed using Morris Water Maze (MWM) test. A battery of biochemical tests such as brain thiobarbituric acid reactive species (TBARS), reduced glutathione (GSH), superoxide dismutase (SOD), brain acetylcholinesterase (AChE) activity, myeloperoxidase (MPO) activity and total serum cholesterol levels were measured. Administration of high fat diet significantly impaired the learning and memory and also deleteriously affected the biochemical parameters. Administration of forskolin (20 mg/kg, p.o.) for 14 days significantly attenuated high fat diet induced memory deficits and the biochemical alterations. Combined administration of forskolin and Pregnane X receptor (PXR) antagonist, Ketoconazole (25 mg/kg, p.o.) significantly reduced the beneficial effects of forskolin in HFD treated rats. This study demonstrates that improvement of memory by forskolin administration may occur as an outcome of its antioxidative, anticholinergic, anti-inflammatory, hypolipidemic and amyloid lowering potential. The study also proposes the possible involvement of Pregnane X receptors in the pathophysiology of experimental dementia.
