Instrument Scale up Chromatograms 50 μL analytical injection of legume extract 4 mL preparative injection of legume extract, full scale. Note the extended range absorbance maximum of 8.5 abs
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
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
