ENHANCEMENT OF TOTAL PHENOLIC, L-DOPA AND PROLINE CONTENTS IN GERMINATING FAVA BEAN (VICIA FABA) IN RESPONSE TO BACTERIAL ELICITORS

Effects of seed hydropriming in presence of exogenous proline on chilling injury limitation in Vigna radiata L. seedlings

“…Vertical bars represent standard errors (n = 9-12). Different letters in the particular series indicate a significant difference at P < 0.05 according to Duncan's multiple range test It was shown that Pro was involved in production of phenolics which, similarly as proline, scavenge free radicals (Shetty et al 2001;Janas et al 2000). We noted similar effect-the amount of soluble phenols in Vigna radiata seedlings was higher in H than control ones (data not shown).…”

“…Pro accumulation is a widespread phenomenon among plants under stress conditions connected with water deficiency and has been associated with osmoregulation (Hyun et al 2003;Hare and Crees 1997;Shetty et al 2001). In addition to act as an osmoprotectant, several possible physiological roles have also been attributed to the supraoptimal level of Pro such as stabilization of proteins, prevention of heat denaturation of enzymes and as a scavenger free radicals including hydroxyl radical (Hsu et al 2003;Hare and Crees 1997), a buffer in cellular redox potential, a major constituent of cell wall structural proteins, which may provide mechanical support for cells (Matysik et al 2002).…”

Biological sources of L-DOPA: An alternative approach

“…Among the various species of Mucuna, M. holtonii, M. pruriens and M. monosperma were having promising L-DOPA content in their seeds. Fava bean (Vicia faba), seed sprouts, pods, and broad beans are one of nature's best plant sources of L-DOPA widely cultivated legume, commonly consumed and have anti-Parkinson's effect [52]. Shoot and callus cultures of banana showed accumulation of L-DOPA when the culture supplemented with tyrosine and phenylalanine.…”

Simultaneous Determination of Levodopa and Carbidopa from Fava Bean, Green Peas and Green Beans by High Performance Liquid Gas Chromatography

“…This procedure was dependent on an effective removal of the many interfering matrix components that vitiate the HPLC analysis. Several unknown endogenous electroactive compounds which are present in Baghala, were eliminated by the purification step, or they were suppressed by the pre-treatment or the detection conditions L-dopa, combined with C-dopa, constitutes one of the most frequent medications in the treatment of Parkinson's disease [15][16][17].…”

“…Parkinson's disease is a progressive neurodegenerative disease which is caused by an imbalance of dopamine and acetylcholine in the brain L-dopa is the standard therapy for Parkinson's disease and its supplementation by fava bean ingestion is being explored. Fava bean consumption has been shown to increase the levels of L-dopa in the blood, with a marked improvement in the motor performance of the patients ('ON' period), without any side effects [8][9][10]. This might be due to the other products which are derived from fava beans, which probably complement the anti-Parkinsonian effect, and, therefore, L-dopa, in the natural fava bean background, was observed to show positive clinical benefits.…”
