Nuttalline (Rf 0.39). Detailed analysis of the MS, used in conjunction with the data of Spiteller et al., [1] confirmed the structure as a 4-hydroxylupanine. The IR and MS were identical with those obtained by Goldberg and Balthis [2] for nuttalline. However, the mp (64-65") does not agree with that reported (108")[2]. Many members of the plant family Leguminosae have been investigated and found to contain various lupin alkaloids, but to our knowledge this is the first reported investigation of a member of the genus Lebeckia. Furthermore the alkaloid nuttalline is not of common occurrence having been only once before reported (from Lupinus nuttallii).
