Pharmacological Properties of Calotropis Species

Calotropis species, notably Calotropis procera and Calotropis gigantea, have long been used in traditional medical systems across Asia, Africa and the Middle East. Contemporary studies reveal a rich array of bioactive compounds including cardenolides, phenolics, flavonoids and cysteine proteases. Cardenolides such as calotropin exhibit potent cardiotonic and antitumour activity, acting through modulation of ion transport and apoptotic signalling. Phenolic and flavonoid constituents confer strong antioxidant and hepatoprotective effects, stabilising free radicals and supporting liver enzyme function. Latex and leaf extracts demonstrate anti-inflammatory efficacy via inhibition of histamine, bradykinin and prostaglandin mediators. Antimicrobial and molluscicidal properties have been attributed to sterols, fatty acids and glycosides, with efficacy against bacterial pathogens and vector snails. Molecular investigations have uncovered the genetic basis of cardiac glycoside biosynthesis and identified candidate genes for metabolic engineering. Together, these findings underscore the global significance of Calotropis as a versatile source of pharmacological agents with applications in oncology, infectious disease control, inflammation management and cardiovascular support.

Research from Nature Portfolio

Recent analyses of Calotropis procera leaf extract have characterised its phytochemical profile, revealing high levels of p-coumaric acid, total phenols and flavonoids. Antioxidant capacity was confirmed by scavenging assays, while antimicrobial tests showed selective inhibition of Escherichia coli and Staphylococcus aureus. In vitro cytotoxicity assays against colorectal cancer cells demonstrated moderate inhibition, indicative of potential adjunctive anticancer use. In parallel, de novo transcriptome sequencing of C. procera stems has unveiled over thirty transcripts linked to terpenoid, steroid and cardenolide pathways. Stage- and tissue-specific expression patterns correlate with cardiac glycoside accumulation, and wound-induced upregulation confirms stress-responsive biosynthesis. These genomic resources lay the groundwork for metabolic engineering aimed at enhancing yield and tailoring bioactive profiles.
