We report the isolation and structural determination of fourteen iminosugars, containing five pyrrolizidines and five indolizidines, from Castanospermum australe. The structure of a new alkaloid was elucidated by spectroscopic methods as 6,8-diepi-castanospermine (13). Our side-by-side comparison

Australine [(1R,2R,3R,7S,7aR)-3-(hydroxymethyl)-1,2,7-trihydroxypyrrolizid ine] is a polyhydroxylated pyrrolizidine alkaloid that was isolated from the seeds of the Australian tree Castanospermum australe and characterized by NMR and X-ray diffraction analysis [Molyneux et al. (1988) J. Nat. Prod.

Crude sample solution prepared from the seeds of Castanosperum australe was fractionated by preparative liquid chromatography. The fractions thus obtained were subsequently analyzed by means of thermospray liquid chromatography-mass spectrometry (tsp lc-ms). Under the conditions employed,

A new indolizidine alkaloid has been isolated from the seeds of Castanospermum [1] australe and identified as 7-deoxy-6-epi-castanospermine by ms and 1H- and 13C-nmr spectroscopy. The alkaloid is the first trihydroxylated indolizidine to be isolated from this plant and may represent an intermediate

During times of pre-European Australia, indigenous people utilized methods of food procurement that resulted in toxic phytochemicals from plants entering their waterholes. This paper focuses on three of these plants, namely the leaves of Acacia colei and Duboisia hopwoodii, which were used by
