摘要：

The novel iridal 10 has been isolated from rhizome extracts of Iris foetidissima. Its structure was established by spectroscopic methods and oxidative degradation. Final proof of the spirobicyclic nature of the compound – a new feature in the triterpenoid field – was afforded by the correlations observed in the 2D‐HMBC‐ (1H‐detected multiple‐bond heteronuclear multiple‐quantum coherence) spectrum. The possible biogenesis of this unusual compound is discussed. Copyright © 1990 Verlag GmbH & Co. KGaA, Weinheim
