Hello,
I currently have a product that has a small amount of melatonin dissolved in it (aqueous solution), and I need a sufficient amount to get a reading on an IR spec. I was thinking of doing an extraction in a sep funnel using DMSO-does anyone have any resources, links. or experiences with this? Thank you!
If you have access to LC, you can run a standard for the retention time and then collect a fraction of the eluant to catch the melatonin. I used to do that for LSD before the capillary columns could separate LSD from lampa, but the method is quick and easy. Run enough samples thru the LC to get enough to run ir with.
Please look at the following below links which may help you in your analysis:
