The Sex Pheromone of the Pine Brown-Tail Moth, Euproctis terminalis (Lepidoptera: Erebidae).

The pine brown tail moth, Euproctis terminalis (Walker 1855), is a periodic pest in pine plantations in South Africa. The larvae feed on pine needles and can cause severe defoliation when population densities are high. Population densities fluctuate temporally and spatially, complicating the prediction of potential growth loss and tree mortality.

Bioactive Lignans from .

Phytochemical investigation of extracts of the stems of led to the isolation of nine lignans that included four known compounds, namely, hinokinin (), savinin (), medioresinol (), and two cubebins (,), three new butyrolactone lignans (-), and butyrolactol lignans -. The structures of the new compounds were established using 1D and 2D NMR and HRESIMS data. The absolute configurations of the new lignans were determined from their ECD data and the Mosher's ester method.
