Insecticidal action of Drimys brasiliensis Miers on black citrus aphid

Revista Ciência Agronômica
The aim of this study was to evaluate the insecticidal effects of a hexane fraction and polygodial compound obtained from Drimys brasiliensis roots on the mortality of adults and nymphs of Toxoptera citricida (black citrus aphid). For the hexane fraction,

Potentiation by Polygodial of the Respiration Inhibiting Activity of Maesanin inCandida utilis

Agricultural and Biological Chemistry, 1989
Maesanin, a metabolite isolated from the fruit of Maesa lanceolata (Myrsinaceae), was devoid of antifungal activity. However, when maesanin was combined with sub-inhibitory concentrations of a sesquiterpene dialdehyde polygodial known to affect the fungal cell membrane, antifungal activity was observed. The synergistic growth inhibition in malt extract

Drimane-Type Sesquiterpenoids as Chemosystematic Markers of Canellaceae

Journal of the Brazilian Chemical Society, 1999
Polygodial, isopolygodial, mukaadial and polygonone were isolated for the first time from Capsicodendron dinisii. Thus, with respect to drimane-type sesquiterpenoids of the Canellaceae, the close affinity of the South American genus Capsicodendron with ...

Hetero-Diels–Alder reaction of halogenated quinones with a polygodial-derived azadiene

Tetrahedron Letters, 2002
The reaction between polygodial dimethylhydrazone and haloquinones under an air atmosphere is described. The terpene moiety undergoes a degradative oxidation to an 11-norsequiterpene ketone containing a quinolinequinone skeleton.

Practical isolation of polygodial from Tasmannia lanceolata: a viable scaffold for synthesis

Organic & Biomolecular Chemistry, 2015
Polygodial, was efficiently extracted and isolated in gram-scale quantities (3.3% w/w) from Tasmannia lanceolata (Tasmanian native pepper) using a pressurised hot water extraction (PHWE) technique that utilises an unmodified household espresso machine.

Plant part substitution as a sustainable conservation strategy for some medicinal plants based on phytochemical equivalence

Discover Plants
Medicinal flora represents an essential source of bioactive substances for both conventional and contemporary medicine; nevertheless, excessive extraction of non-renewable parts such as roots, bark, and heartwood has led to significant reductions in wild
