%X An alkaloid of Crotalaria leschenaultii DC., previously reported as crispatine and now named crotaleschenine, has been re-investigated and shown to be (7&#946;,8&#945;-H,12&#945;,13&#945;,14&#945;)-12&#946;-hydroxy-1,2-didehydrocrotalane-11,15-dione.1 Spectroscopic data are presented and the stereochemistry determined by X-ray crystallography. The esterifying acid of crotaleschenine is identical with that of retusine , which is thereby determined as (1a,7&#946;,8&#945;-H,12&#945;,13&#945;,14&#945;)-12&#946;- hydroxycrotalane-11,15-dione.
