College of pharmacy, Electronic Zone, M.I.D.C. Hingna road, Nagpur. 440016, India. ABSTRACT In our country, more than 2000 medicinal plants have been recognized. Griffonia simplicifollia Fabaceae Family, is an important medicinal plant for antidepressant. Because L-5-Hydroxytryptophan which is de-rived from seeds of Griffonia simplicifolia is an industrial source of a serotonin precursor. Its medicinal usage has been reported in the traditional systems of medicine. Serotonin is an important in regulating brain chemistry and is especially important in problems such as depression. Therefore, supplementing with Griffonia seed can raise serotonin levels and provide relief from depression and insomnia. The present review article discuss about G. Simplicifollia, its major active constituents, and its role in depression. Key words: Griffonia Simplicifolia, Depression, Serotonin. INTRODUCTION The World Health Organization predicts and its axons project to frontal cortex where they may depression will become the second-most burdensome have important regulatory functions for mood, basal disease in the next decade, with the greatest burden in ganglia where limbic areas where they may modulate North America and the United Kingdom (WHO, 2001). emotions, particularly anxiety. (Hindmarch, 2001; Gerard Currently, major depression accounts for 33.3% of et al., 2006). Serotonergic projections also arrive in the patients in the United States, (Unutzer, 1857) and, at 160 hypothalamus where they can regulate eating,appetite, an million prescriptions annually, antidepressants are the d weight as well as drive and pleasure and regulate the sle most prescribed medication, despite the fact that recent ep‐wake cycle. (Van et al., 1972) meta-analyses show these as no better to treat mild to Hence, it was clear that supplementing with moderate depression (the major prescriptive reason) than Griffonia seed can raise serotonin levels and provide placebo. (Fournier, 2010) Serotonin is an important in relief from depression and insomnia. (Wang, 2013) regulating brain chemistry and is especially important in Because Griffonia simplicifolia is the largest source of the problems such as depression. Clinical depression compound 5-HTP. Its seeds contain up to 20% 5-HTP, by is due to impairment of central monoaminergic function, a weight. Studies that have been done on Griffonia deficiency in the neurotransmission mediated by serotonin simplicifolia suggest that when supplemented as an herb, (5‐HT), 5-hydroxytryptamin, norepinephrine (NA) and it may rival the effects of supplementing 5-HTP in dopamine (DA). The monoamine concentrations may be a isolation. The lowest effect dose for rats is 25mg/kg of ltered as a result of disrupted synthesis, storage or release bodyweight, which is about 4mg/kg of Griffonia or the concentrations may be normal but the postsyna ptic simplicifolia extract, assuming 20% 5-HTP content. This receptors and / or sub‐cellular messenger activity may be translates to following human doses; 275mg Griffonia impaired Serotonin’s cell bodies are located in brain raphe (55mg of 5-HTP) for a 150 lb person, 350mg Griffonia (70mg of 5-HTP) for a 200 lb person 450mg Griffonia Corresponding Author (90mg of 5-HTP) for a 250 lb person. It is unknown whether Griffonia simplicifolia has other bioactives other HD Mehta (Upadhye) than 5-HTP. The human dosages listed above are derived Email: [email protected] from rodent studies, and are not optimal, which is why 77 Mehta HD et al. / International Journal of Phytopharmacology. 6(2), 2015, 76-79. they are different from the optimal dose of 5-HTP. identified. Alkaloids 1, 2 and 4 showed growth inhibitory (Pathak, 2010) effects on the HepG2 cell line with IC50 values of 23.5, 9.6 and 19.3 μmol·L(-1), respectively.
