摘要：

A new diosgenin derivative designated denfigenin has been isolated from the petrol extract of the whole plant Dendrobium fimbriatum, along with diosgenin and defuscin (n-triacontyl p-coumarate). Denfigenin was shown to be (25R)-22-alpha-O-spirost-5-ene-3-beta,16-alpha,17-alpha-triol mainly based on H-1 and C-13 NMR spectral studies. Its molecular conformation has also been discussed.
