HPLC analysis of various alkaloids

A number of papers have been published on the HPLC analysis of alkaloids in order to study the possibilities for such analyses in general. The papers comprise a wide variety of alkaloids and HPLC systems for their separation. The data published in these papers may be useful in connection with many separation and other HPLC problems in the analysis of alkaloids. Therefore some of the data of general interest are summarized in the present chapter. However, in other chapters of this book, HPLC systems that may be useful for alkaloid analysis in general, have also been dealt with (see Table 2.1). [Pg.235]

Walton and co-workers reported the analysis of various alkaloids by means of ligand--exchange chromatography. As stationary phases, ion-exchange materials loaded with metal-ions that are capable of giving ammonia complexes (Cu++,N1++,Zn++ and Ag+) were used. [Pg.235]

A cation-exchange stationary phase for the separation of various drugs, including several 7 8 [Pg.235]

Twitchett and Moffat tested a microparticulate octadecyl stationary phase for the analysis of some drugs, including several alkaloids. For the systems tested (methanol - aqueous ammonium phosphate buffers, pH varying from 3 to 9) severe tailing was observed for basic drugs, making these systems less suitable for the analysis of such compounds.

The analysis of a series of basic drugs by means of reversed-phase HPLC was reported in [Pg.235]
