Abstract Forrestiacids A (1) and B (2) are a novel class of [4+ 2] type pentaterpenoids
derived from a rearranged lanostane moiety (dienophile) and an abietane unit (diene) …

A preliminary phytochemical investigation on the 90% MeOH extract from the twigs and
needles of the vulnerable conifer Keteleeria fortunei led to the isolation and characterization …

Seven [4+ 2]-type triterpene–diterpene hybrids derived from a rearranged or a normal
lanostane unit (dienophile) and an abietane moiety (diene), forrestiacids E–K (1–7 …

Two new triterpenoids, spirochensilides A (1) and B (2) were isolated from Abies
