A copious white sap flows whenever stems or leaves are cut. Giant milkweed roots were found to have few branches and reach depths of 1.7 to 3.0 m in Indian sandy desert soils. Leaves are oblongobovate to nearly orbicular, short-pointed to blunt at the apex and have very short petioles below a nearly clasping, heart-shaped base. The leaf blades are light to dark green with nearly white veins. They are 7 to 18 cm long and 5 to 13 cm broad, slightly leathery, and have a fine coat of soft hairs that rub off.

Distribution and Occurrences : 

Distribution and Occurrences Calotropis procera is native to West Africa as far south as Angola, North and East Africa, Madagascar, the Arabian Peninsula, southern Asia, and Indochina to Malaysia. The species is now naturalized in Australia, many Pacific islands, Mexico, Central and South America, and the Caribbean islands. Giant milkweed favors open habitat with little competition. This condition is most completely met in overgrazed pastures and rangeland. Other common habitats are beachfront dunes, roadsides, and isturbed urban lots. The species grows in dry habitat (150 to 1000 mm precipitation) and sometimes in excessively drained soils in areas with as much as 2000 mm of annual precipitation. Calotropis procera may be found in areas up to 1,000 m in elevation in India.

These compounds includes various chemicals which are useful for various activities. After chemical screening of latex of Calotropis procera. The latex reveled that the plants contain cardenoids such as calotropin, calotoxin , uscharin, usechardin, glycoside calotropaginin, choline, o-pyrocatechuric acid, Benzoyllineolone, benzoylisoloneolane uzariganin and syriogenin. In the root of the Calotropis procera pentacyclic triterpenes, alkaloid, cardinolides phytosterols and triterpenoid saponins have been isolated from roots. The leaves, flower and roots contained high amount of ash and protein(10.9-11.7%) with varying quantities of alkaloids, leaves contained calotropin and calotropegenin.

Phytochemistry :
