A Review on Phytoconstituents and Biological activities of Cuscuta species.

The genus Cuscuta belonging to the Cuscutaceae family comprises of about 100-170 species spread around the world. Although several species have been studied for their phytochemical characterization and biological activities but still many species are yet unexplored till date. Cuscuta are parasitic plants generally of yellow, orange, red or rarely green color. The Cuscuta species were reported rich in flavonoid and glycosidic constituents along with alkaloids, fatty acids, fixed oil, minerals, essential oil and others phytomolecules also etc. Flavonoids and other molecules of Cuscuta species were reported for different types of biological activities such as antiproliferative activity, antioxidant activity, anti-inflammatory, hepatoprotective, antimicrobial and anxiolytic activity, while some other flavonoids have exhibited potential antiviral and anticancer especially in ovarian and breast cancer activities. This review is an attempt to compile all the available data for the 24 different of Cuscuta species on the basis of different types of phytochemical constituents and biological studies as above.
