The existence of secondary metabolites in plants have helped to produce natural products or botanicals that can be used as an alternative to chemical or synthetic pesticides. Although Cyperus is considered as aggressive weeds due to its invasive characteristics and may cause rice yield loss, but most of the species have been commonly used for medicinal purpose. Cyperus rotundus were commonly known to possess many biological activities. However, the study on this species have been extensively conducted thus this review will show the chemical compounds found in other selected Cyperus species along with the properties exerted by the species. Terpenes are among the secondary metabolites involved in antimicrobial activities while polyphenols, alkaloids and essential oils are the secondary metabolites that are responsible in antioxidant activities. Insecticidal activities were mostly discovered through the extraction of essential oils.
