Introduction
• Griffonia simplicifolia is a tall bushy vine found in Ghana, Nigeria, Liberia, Ivory Coast, Cameroon and Congo
• The vine produces pods containing 3 large legumes• The legumes are a rich source of 5-hydroxytryptophan
(5HTP) • 5-hydroxytryptophan produced by the human body from
the essential amino acid L-hydroxytryptophan (LT)• 5-HTP has been clinically used to increase serotonin
production to combat many mental illnesses like depression and schizophrenia among others

37
Purity Check
• Fraction between 3 and 3.5 min in the preparative chromatogram was collected resulting in a fraction volume of 10.1 mL
• Reinjection of the collected fraction onto the Analytical column results in a single peak chromatogram. Overlayed with the PDA peak purity trace, the flat top of the purity trace indicates a pure compound
38
Discussion
• A good estimate of the amount of the % of HTP in dry
Griffonia seeds can be made
• The entire 10 mL fraction contains 17.2 mg
• 1gm of seeds contains 215mg of 5HTP
• Approx. 20% dry weight
• G. Simplicifolia seeds are a very rich source of 5HTP
