Dear Friends,
I am going to post in this week my collection of a list of several derivatizing agents/ visualization indicators which will prove helpful to you also.
continued from last post......................
Antimony (III) chloride
For detection of flavonoids
Spray with a 10% solution of antimony (III) chloride in chloroform
Results: Fluorescing spots in long wavelength light (360nm).
Antimony (III) chloride
For detection of vitamins A & D, carotenoids, steroids, sapogenins, steroid glycosides, terpenes
Spray with a solution of 25g antimony (III) chloride in 75ml chloroform (generally a saturated solution of antimony (III) chloride in chloroform or carbon tetrachloride is used).
Heat 10min at 100C, view under long wavelength light (360nm).
Bromine / Carbon tetrachloride
For detection of organothiophosphorous pesticides
Place chromatogram in a chamber with a 10% bromine and tetrachloride without contact with the liquid.
