- Cyperus, like other plants, has numerous chemical constituents, many of which may show pharmacological activity, but the main active components appear to be the sesquiterpenes. These are aromatic, spicy tasting molecules. Among the main sesquiterpenes identified in cyperus rhizomes thus far are: α-cyperone, β-selinene, cyperene, cyperotundone, patchoulenone, sugeonol, kobusone, and isokobusone that may scientifically explain the folk- and alternative-medicine uses.
- Cyperus also contains other terpenes, such as the commonly occurring plant component pinene (a monoterpene), and several derivatives of the sesquiterpenes, such as cyperol, isocyperol, and cyperone. These active constituents are found in the volatile oil of cyperus rhizomes, which makes up only about 0.5-1% of the dried rhizome; prolonged cooking of the herb will cause loss of some portion of these constituents. Their main pharmacological actions may be antispasmodic and analgesic effects.
