Abstract

Two new diterpenoids, 14α-hydroxy-9α,13α-epoxylabd-5(6)-en-7-on-16,15-olide (1) and 13ξ-hydroxylabd-5(6),8(9)-dien-7-on-16,15-olide (2) along with six known diterpenoids were isolated from the aerial parts of Leonotis leonurus R. Br. These structures were determined on the basis of spectroscopic analyses. Some of the isolated compounds showed weak to moderate estrogen sulfotransferase inhibitory activity.
