A new oleanene triterpene from Gladiolus segetum Ker-Gawl.
A new pentacyclic oleanene triterpene, 2beta, 3beta, 16alpha, 28-tetrahydroxy-olean-12-ene-23-oic acid (1), as well as the known pentacyclic triterpene medicagenic acid (2), have been isolated by different chromatographic techniques from the acid hydrolysate of the saponin fraction of Gladiolus segetum. The identification of these compounds was established by different methods of physical, chemical and spectral evidence.
