Summary:Five new fernane type triterpenoids, ferna-7, 9(11)-diene-3α, 16α-diol (1), 3α, 16α-dihydroxyferna-7, 9(11)-dien-12-one (2), ferna-7, 9(11)-diene-3α, 16α, 19α-triol (3), 3α, 16α-dihydroxyfern-8-en-11-one (4) and 3α, 16α-dihydroxyfern-8-ene-7, 11-dione (5), were isolated from the leaves of Lonicera gracilipes var. glandulosa MAXIM. The structures of these compounds were elucidated on the basis of spectroscopic evidence.
