Two 15beta-hydroxycardenolides (1,2) and a 16alpha-hydroxycalactinic acid methyl ester (3) along with eleven known compounds including 16alpha-hydroxycalotropagenin, coroglaucigenin, 16alpha-hydroxycalotropin, calactinic acid, calotoxin, 6'-O-(E-4-hydroxycinnamoyl)desglucouzarin,
Three cardenolide glycosides, calotropin (1), frugoside (2), and 4'-O-beta-D-glucopyranosylfrugoside (3), were obtained as the cytotoxic principles of "akond mul" (roots of Calotropis gigantea L.). The cytotoxicity of these compounds against various cell lines of human and mouse origin was tested.
We have studied the ethyl acetate fraction of the methanolic extract of the root barks of Calotropis procera (Asclepiadaceae) from Egypt. Bioassay-directed fractionation and final purification of the extract resulted in the identification of a new cardenolide glycoside named proceraside A (1)
The bioactive compounds proceraside A, frugoside and calotropin, which were extracted from the root bark of Calotropis procera (Aiton) W.T. Aiton (family Asclepiadaceae), were recently reported to inhibit the growth of inhibition against various human cancer cell lines in vitro. However, their modes
