摘要：

From the monohydroxy steroidal sapogenin fraction of Cordyline cannifolia R. Br. leaves, 3-epf-neotigogenin (1a) and 3-epi-tigogenin (1b) were isolated and characterized from tic, ir, nmr and mass spectral data and by conversion into known spirostanes. Neither compound has been isolated previously from a plant source. In addition, yamogenin and diosgenin were found. Tic methods are described for the separation of 3α and 3β-monohydroxy spirostanes. © 1979, American Chemical Society. All rights reserved.
