                           densitograms obtained for four subsequent developments of the extract from a
                           medicinal plant (Radix rhei), obtained according to the reversed PMD (MGD)
                           method (71). The technique has been successfully applied to the separation of com-
                           pounds from complex plant extracts (71,72), as well as from food and beverages
                           products (73).
