Hernández, Rosendo Suárez, Ernesto Fundación Juan March Ministerio de Educación y Ciencia (España) 7 pages, 1 table, 1 scheme.-- For Part XVII see A.G. González, R. Freire Barreira, C. García Francisco, J.A. Salazar Rocío and E. Suárez López, An. Quím. 68, 1063 (1972). From the stems and leaves of Semele androgyna L. four new steroid sapogenins have been isolated: isoandrogenin A (Ia) and B (Id), their structures being determined as the 25S- and 25R-isomers of spirost-5-en-1 β, 3β, 25-triol, and androgenin A (IIa) and B (IIc) corresponding to the 25S- and 25R-isomers of (20S, 22S, 25)-furost-5-en-22, 25-epoxy-1 β, 3β, 26-triol. One of us (R.H.) thanks the Ministerio de Educación y Ciencia for a "Formación de Personal Investigador" fellowship. This work was realized within the Programme 1971 conceded by the Foundation Juan March. 2009-09-09T07:15:41Z 2009-09-09T07:15:41Z 1973 artículo http://purl.org/coar/resource_type/c_6501 Revista Latinoamericana de Química 4: 45-51 (1973) 0370-5943 (Print) http://hdl.handle.net/10261/16747 http://dx.doi.org/10.13039/501100009154 en http://www.relaquim.com/ open 2373 bytes 840339 bytes text/plain application/pdf Universidad Nacional Autónoma de México |
