Insecticidal alkaloids from the seeds of Macleaya cordata on cotton aphid (Aphis gossypii)

The effect of two different botanical extracts on Aphis gossypii Glover 1877 (Hemiptera: Aphididae) and Tetranychus urticae Koch 1836 (Acari: Tetranychidae)

“…The efficacy of 8-hydroxydihydrochelerythrine and 8-methoxydihydrosanguinarine, the principal components isolated from Macleaya cordata (Willd. ), on A. gossypii was investigated by Baek et al (2013) under laboratory conditions. They indicated that these alcohol extracts caused mortalities of 76.1 and 73.6% in A. gossypii, respectively.…”

Phytochemical and biological research of Chelidonieae pharmaceutical resources

“…8-Hydroxydihydrochelerythrine and 8-methoxydihydrosanguinarine, isolated from the seeds of Macleaya cordata, decreased the survival of the cotton aphid by 76.1 AE 7.9% and 73.6 AE 14.6% at 100 ppm, respectively (Baek et al, 2013).…”

Natural Product-Based Biopesticides for Insect Control

“…There are recent reports on natural alkaloids from different chemical classes with insecticidal effects. For example, dihydroagarofuran alkaloids, 264,492 didehydrostemofoline alkaloids from stemona plant, 493 benzophenanthridine alkaloids, 494 indoloquinazolin alkaloids, 328 isubutilamide alkaloids, 495 phenanthrene-indolizidine alkaloids, 496 pyrrolizidine alkaloids 404 and others. Dihydroagarofuran sesquiterpene esters and alkaloids are the main compounds exhibiting insect antifeedant and insecticidal activities which have already been isolated from species of Celastraceae.…”
