• 論文の詳細を見る

• Alkaloids in Nandina domestica were analysed by means of ion-pair and ion-suppression HPLC and TLC-densitometry. In HPLC, both photodiode-array detector and LC-MS were utilized. The ion-pair I{PLC system gives separation by an isocratic elution system, and in the ion suppression HPLC system using a gradient elution system containing ammonium acetate, LC-MS is possible, which is not possible with the former system. Tertiary and quaternary bases were also separated on silica gel FTPTLC plates. TLC-densitometry was successfully used for both identification and estimation of quantities. The nantenine and protopine contents in commercial nandinae fructus were determined by ion-pair HPLC and TLC-densitometry, and both results agreed well with each other. In addition to the alkaloids already known to be contained, pseudocolumbamine was obtained from the stems: pseudoberberines have not been isolated from the plant before.
