Structure of a new neo-clerodane diterpenoid from Ajuga pseudoiva leaves and its insect antifeedant and antibacterial activities
Written by sctunisie no commentsFrom the leaves of the plant Ajuga pseudoiva a new neo-clerodane diterpenoid, Hativene D, has been isolated. Its structure was established by spectroscopic means. The antifeedant activity of this compound has been studied against Egyptian cotton leafworm Spodoptera littoralis (Boisd.) (Lepidoptera) by application of the leaf disk method. This substance exhibited an interesting activity even at 1 ppm. Structure-activity relationship is discussed. The antibacterial effect of this neo-clerodane has been also tested.
