planchonii leaves was subjected to various qualitative and quantitative phytochemical screenings to detect the presence of the following bioactive principles: alkaloids, steroids, anthraquinones, cardenolides
, phenols, flavonoids, tannins, triterpenes, glycoside, and saponins.
Red coloration indicated the presence of cardenolides
or [alpha], [beta]-unsaturated lactones.
A brown ring at the interface indicated the presence of a deoxysugar characteristic of cardenolides
Fluorescence detection of cardenolides

A phytochemical analysis of carica papayaleaves discovered the presence of papain chymopapin alkaloids flavonols flavonoids saponins tannis cardiac glycoside anthraquinones reducing sugar steroids phenols and cardenolides
To further explain, larvae require cardenolides
from said plants in order to survive and grow, a phenomenon discovered by Swiss Nobel laureate Tadeus Reichstein.
Plants belonging to this genus are rich in esteried polyhydroxypregnane glycosides, some of which showed antitumor activity and others were postulated as precursors of cardenolides
Tarsal contact chemoreceptor response to glucosinolates and cardenolides
mediating oviposition in Pieris rapae.
are a secondary chemical that milkweeds use as a defense compound; many plant and animal species use cardenolides
in this manner, in particular, monarch butterfly larva sequester them from feeding on milkweed.
Molecules with similar structures include cardenolides
, such as digoxin and digitoxin, which are known substrates of ABC transporters (de Lan noy and Silverman 1992; Cavet et al.
