Six new migrated hopane triterpenoid alcohols, viz. pteron-14-en,7α-ol (1), fern-9(11)-en-3α-ol (2), fern-7-en-3α-ol (3), adian-5(10)-en-3α-ol (4), adian-5-en-3α-ol (5) and fern-9(11)-en-28-ol (6) were isolated along with many other known triterpenoids from fresh fronds of Adiantum capillus- veneris. Their structures were elucidated by detailed two dimensional-NMR analyses and/or chemical correlations.

The powder coating of a bamboo, Lingnania chungii McClure (= Bambusa chungii) was found to be a rich source of the 3-oxo pentacyclic triterpenes (25percent on the recovery basis by chromatography on silica gel) which contained friedelin, arborinone and glutinone as the major components accompanied by minor amounts of α- and β-amyrenones.A simple procedure for isolation of the friedelin is described.All proton and carbon-13 nuclear magnetic resonance signals for arborinone, friedelin and glutinone were assigned.Keywords Lingnania chungii; Bambusa chungii; Gramineae; arborinone; friedelin; glutinone; 1H-NMR; 13C-NMR
