Abstract

A simple sensitive and rapid method is herein described for the qualitative and quantitative chemical assessment of the fractional composition of carbonyl functionalities in natural products. Several extracts, essential oils, fixed oils, oleoresins and pure natural isolates were directly analyzed by applying a simple colorimetric procedure, by LC or DE-TLC using o-dianisidine as a chromogenic reagent. The reagent is found to be very useful and could also be used in the microscopic examination of powdered herbal products.
