TL;DR: The isolation from Alexa leiopetala and identification by X-ray crystal structure analysis of (1R,2R,3R,4R,5S,6S)-2-hydroxymethyl-1-azabicyclo[3.3.0]octan-3,4,6-triol], a unique pyrrolizidine alkaloid, is described in this paper.

TL;DR: Castanospermine, a physiologically active polyhydroxylated indolizidine alkaloid first isolated from seeds of Castanospermum australe, has been isolated from the dried pod of Alexa leiopetala and tentatively identified in seven other species of the same genus.
Journal ArticleDOI
Two alexines [3-hydroxymethyl-1,2,7-trihydroxypyrrolizidines] from Castanospermum australe

TL;DR: Two new alexines have been isolated from Castanospermum australe and the structure of 1 7a-diepialexine was firmly established by X-ray crystallographic analysis of the corresponding 1,7-isopropylidene derivative as discussed by the authors.
