A mosquito larvicidal diterpenoid isolated from Podocarpus totara D. Don ex Lambert
Journal of Entomological Science 35 (4), 474-477
Abstract: Totarol, a diterpenoid phenol isolated from Podocarpus totara (D. Don ex Lambert) root bark, was found to be active against second- and fourth-instar Culex pipiens Coquillett with the 24 h LC₅₀ values of 0.25 and 0.37 µg/mL, respectively. The mosquito larvicidal activity against C. pipiens increased when bioassays were extended to 48 h. Structural elucidation of totarol was by means of ¹H-NMR, ¹³C-NMR, and GC-MS analysis.
