The stationary phase may be a solid or liquid on a solid support. The mechanisms responsible for distribution between phases include surface absorption, ion exchange, relative solubilities and steric affects . High performance liquid chromatography is a useful method for quinolizidine alkaloid analysis, especially when pure standards are available". This method was recently used for alkaloid metabolite extraction and analysis . A simple reversed-phase liquid chromatographic method has been developed for the simultaneous quantitation of four anticancerous alkaloids vincristine, vinblastine, and their precursors catharanthine and vindoline using a specific HPLC column .

Methanol and acetonitrile are the most frequently used water-miscible organic solvents for protein denaturation. The main advantage of using methanol for protein precipitation is that a clear supernatant is obtained and a flocculent precipitate is formed. Acetonitrile, on tire other hand, gives a hazy supernatant with a fine precipitate. The compatibility of tliese solvents with the reversed-phase liquid chromatographic eluents commonly used for separation purposes is an added advantage.
