イネ科植物のトリテルペンおよび関連化合物について(第5報)

Abstract

Distribution of triterpenoids and related compounds was examined for seven species of Gramineae plants with special reference to a chemotaxonomical point of view. The triterpenoids thus identified are shown in Table I. Lupeol methyl ether (VIIa), a new triterpene methyl ether, was isolated from the culms and leaves of Pasparum dilatatum POIR. and identified with the synthetic specimen. Fernenone (IIIc) and 12-ketoarundoin (IIId) have been isolated from a natural source (Zoysia matrella MERR.) for the first time. Some observation on new triterpenoids are also described.
