Glycosylation of Cardenolide Aglycones in the Leaves of Nerium oleander L.
, 1989 Application of [14C]-progesterone to the leaves of Nerium oleander L. (Apocynaceae) resulted in the formation of [14C]-digitoxigenin and [14C]-oleandrigenin glycosides; the labelled aglycones were obtained after hydrolysis from the cardenolide extract ...

Ecosphere, Volume 17, Issue 6, June 2026.Abstract Managing milkweed (Asclepias spp.) is of high conservation concern due to its association with monarch butterflies (Danaus plexippus L.), which are proposed for listing under the Endangered Species Act. To counteract monarch declines, conservation goals aim to establish ≥1.6 billion nonagricultural milkweed stems within the Midwestern United ...

Amurensiosides L-P, Five New Cardenolide Glycosides from the Roots of
Natural Product Communications, 2015 Five new cardenolide glycosides, amurensiosides L–P ( 1 – 5 ), were isolated from the roots of Adonis amurensis . Their structures were determined based on extensive spectroscopic analysis, including two-dimensional (2D) NMR data, and on the results of ...

Calotropis procera GLYCOSIDES ARE MORE EFFECTIVE ON Eobania vermiculata (MÜLLER) THAN METHOMYL AND OTHER PLANT GLYCOSIDES. [PDF]
Journal of Plant Protection and Pathology, 2007 Methomyl and the cardiac glycoside extract, isolated from Calotropis procera, were tested against the terrestrial helicid snail Eobania vermiculata (Müller) by the contact method.

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation
Molecular Ecology, Volume 35, Issue 9, May 2026.ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

New CNS depressant cardenolide glycoside from the roots of Nerium oleander
Results in Chemistry, 2020 A new central nervous system (CNS) depressant cardenolide glycoside named nerioleanderoside (1) was isolated from active n-butanol fraction of the aqueous- ethanolic (5:95 v/v) extract of the fresh dried roots of Nerium oleander.

DISCOVERY OF A HIGHLY ACTIVE MOLLUSCICIDAL EXTRACT AGAINST LAND SNAILS, FROM Nerium Oleander L. [PDF]
Journal of Plant Protection and Pathology, 2007 Nerium oleander L. is the widest spread ornamental plant; it is cultivated every where in Egypt as well as in the whole world. We noticed that snails living very close to the plant do not approach it.

Impact of Consuming ‘Toxic’ Monarch Caterpillars on Adult Chinese Mantid Mass Gain and Fecundity
Insects, 2017 Predators that feed on chemically-defended prey often experience non-lethal effects that result in learned avoidance of the prey species. Some predators are able to consume toxic prey without ill-effect.
