Salvia aethiopis

Using the same strategy, Benrezzouk et al. also reported a naphthoquinone diterpene, aethiopinone, from the roots of Salvia aethiopis L. (Labiatae), possessed 5-LOX inhibition activity with IC50 value of O.llpM without affecting COX and PLA2 pathways [140]. 

Diterpenoid quinones have been isolated from a number of the Labiatae. An o-quinone, ethiopinone (38), has been described as a constituent57 of the roots of Salvia aethiopis (Labiatae) and the known quinones horminone and 7a-acetoxy-royleanone have been isolated58 from S. lanata. The dehydroabietic acid derivative (39) was obtained59 from S. tomentosa. The partial synthesis of the epimeric ring B...
