title: Normethyl pentacyclic and lanostane-type triterpenes from Adiantum venustum.
abstract: Phytochemical studies on the aerial parts of Adiantum venustum resulted in the isolation of normethyl lupane-type, a normethyl oleanane-type and a lanostane-type triterpene. Structures of these triterpenes have been established as 30-normethyl lupane-20-one, 30-normethyl olean-3-one-30 beta-ol and lanost-20(22)-ene-30-ol on the basis of spectral data analyses and chemical methods.
