A new alkaloid (1) containing an indolizidine ring, named tashiromine, was isolated from the stems of Maackia tashiroi (Leguminosae) together with seven lupin alkaloids and ammodendrine.The structure of 1 was determined as IiS.6Rl-5hydroxymethyl-trans-indolizidine or its enantiomer by comparison of the spectral data with those of the synthetic diastereamers of 5-hydoxymethyl-trans-indolizidine.
