摘要：

Five phytoecdysteroids not previously reported in Polypodium vulgare have been isolated from methanol extracts of in vitro cultures of prothalli of this species. Among them, inokosterone, pterosterone and abutasterone had already been identified in other plants, whereas 24-hydroxyecdysone and 5-hydroxyabutasterone are described for the first time. The structure of these compounds was inferred from the corresponding H-1 and C-13 NMR and thermospray-HPLC-MS spectral data. The complete description of the structures includes the stereochemical assignment at C-24, which was 24S for all compounds. This assignation was carried out by C-13 NMR spectroscopic studies of 22,24-benzylidene acetal derivatives.
