Extract of the plant also contains sterols, triterpenes, uzarigenin, syriogenin, proceroside, calotropagenin, and six of its glucosides. Cardenolides, uscharin, sterols and pentacyclic triterpenes, lupeol and calotropinyl acetate are also present in leaves and latex. A new antibacterial cardenolide, proceragenin has been isolated from this plant.
The latex contains five cardiac steroid glucosides with the same aglycone, calotropagenin. Latex also contains α-amyrin, ß-amyrin and ß-sitosterol, calotropin, calotoxin, uscharin and uscharidin. Flowers conatin cyanidin 3-rhamnoglucoside (Rastogi & Mehrotra, 1993; Ghani, 2003). Plant also contains o-pyrocatechuic acid; cardenolides (calotropin, calotoxin, uscharin and uscharidin) (Asolkar et al., 1992).
