Labdane is a natural bicyclic diterpene. It forms the structural core for a wide variety of natural products collectively known as labdanes or labdane diterpenes. The labdanes were so named because the first members of the class were originally obtained from labdanum, a resin derived from the gum rockrose.^[1]^[2]

A variety of biological activities have been determined for labdane diterpenes including antibacterial, antifungal, antiprotozoal, and anti-inflammatory activities.^[3]

Example labdane derivatives

Forskolin
Stemodene
Isocupressic acid - is an abortifacient component of Cupressus macrocarpa.^[4]
Sclareol
Medigenin
