ABSTRACT.-From the fruits of Cord>line australis, the new steroidal sapogenin australigenin [5a-spirost-25(27)-ene-lp,3P-diol] has been isolated and characterized from ir, pmr, and mass spectral data. Thirteen other steroidal sapogenins have been identified, including polygenin, lp-hydroxycrabbogenin, and sceprrumgenin.
The steroidal sapogenins yielded by the leaves of many Cordyfinespecies (Agavaceae) have been recorded (1-8),but no work has been published on these compounds from the fruits and seeds of species within the genus. In this paper, we report the steroidal sapogenins found in extracts of fruits of Cordyfineaustralis Hook. f. ; one of these compounds, australigenin, is a new dihydroxyspirostane. MATERIALS AND METHODS EXTRACTIONOF SAPOGENINS.
