Normal- and bonded-phase liquid chromatography with photodiode array detection of maytansinoids
Autor: Eike Reich, Albert T. Sneden
Publikováno v: Journal of Chromatography A. 763:213-219
Maytansinoids obtained from Maytenus species are known as potential anti-cancer drugs. Investigation of new plant species for the presence of unknown maytansinoids as well as synthetic work requires a reliable analytical and semipreparative normal-ph

Negative-ion fast atom bombardment and tandem mass spectrometric investigation of phenylpropanoid glycosides isolated fromPolygonum pensylvanicum L
Autor: M. L. Zimmermann, T. L. Sumpter, A. T. Sneden
Publikováno v: Journal of Mass Spectrometry. 30:1628-1632
Investigation of the novel phenylpropanoid sucrose esters vanicoside A, vanicoside B and hydropiperoside, derived from Polygonum pensylvanicum L., by negative-ion fast atom bombardment and tandem mass spectrometry has elucidated collision-induced dec

Two New Maytansinoids from Maytenus buchananii
Autor: Gretchen M. Larson, Albert T. Sneden, Brian T. Schaneberg
Publikováno v: Journal of Natural Products. 62:361-363
Reinvestigation of fractions derived from large-scale fractionation of Maytenus buchananii led to the isolation of two new maytansinoids. The structures of these principles were determined using electrospray MS, 1H NMR, 13C NMR, and 2D NMR techniques
