Purple nutsedge, Cyperus rotundus L. (Cyperaceae) is an invasive plant grown in all around the world. C. rotundus rhizomes are called "topalak" and an analgesic plant for the treatment of stomach ache in infants, folk medicine in Turkey. The volatile compounds of C. rotundus rhizomes were investigated by Headspace-SPME. Cyperene (30.5% and 28.0%), α-copaene (10.6% and12%) and α-ylangene (7.7% and10.5%) were identified as main volatile components of rhizomes and analyzed at room temperature and 40ºC respectively. This study designed to support detailed studies on underground plant parts volatiles and it is the first time to identification of volatile compounds of raw C. rotundus rhizomes collected from Turkey by Headspace-SPME and GC and GC-MS.

“…Although Cyperaceae are often thought of as weedy and invasive plants, there are a large number of species that are specific to a narrow range of habitats and, therefore, appear to be excellent bioindicators of healthy ecosystems. Also, many sedges are used by local people in handicrafts (Simpson & Inglis 2001), as the basis for perfumes (i.e., Cyperus articulatus, Zoghbi et al 2006).…”

The purpose of this catalogue was to combine the available data from publications, theses, databases, and herbarium specimens from around 120 Herbaria, and colections sampled in Brazilian vegetation during the last 15 years to produce the most complete list, as possible as, of Cyperaceae species for Brazil. We catalogued ca. 1,700 names for 678 species in 42 genera occurring in Brazil. These values represent ca. 15 percent of the species and 40 percent of the genera found in the world. Both subfamilies of Cyperaceae are found in Brazil with Cyperoideae being the most diverse at both generic and specific levels. Although lower species were recorded for the tribes Cryptangieae, Sclerieae, and Trilepideae, these tribes represent a much higher percentage of the world's totals for genera and species. The most diverse genera are Rhynchospora (157 spp.), Cyperus (101 spp.), Scleria (82 spp.) and Eleocharis (69 spp.). Fifteen genera have one species in Brazil, although five of them are monospecific. The most species-rich regions in Brazil are the North and Southeast. There are no genera endemic to Brazil. There are, however, around 200 endemic species, of which 40 are in the genus Rhynchospora. Taxonomic and nomenclatural problems found are pointed under the species. For each catalogued species, the principal synonyms, bibliographic references, distribution within Brazil's five regions, vegetation type, and citation of selected material examined are provided.

“…The majority of the Cyperus species studied are reported to contain different guaiane, caryophyllene and eudesmane derivatives as their major constituents [15][16][17][18][19][20][21][22][23]. Hydroazulene derivatives, such as guaiane, are characteristic metabolites of Cyperus species.…”

The essential oil compositions of the rhizomes of Cyperus conglomeratus (Cyperaceae) collected from Oman and the leaves of two Annonaceae plants, Desmos chinensis var. lawii and Cyathocalyx zeylanicus collected from India were studied by GC, GC-MS and 13 C NMR spectroscopy. Twenty-six compounds, representing 84.4% of the oil were identified in C. conglomeratus, where eugenol (31.3%), α-cyperone (10.5%) and cyperotundone (8.4%) were the major compounds. Twelve compounds, constituting 100%, were identified in D. lawii oil, of which benzyl benzoate (58.7%), -caryophyllene (23.2%), limonene (4.9%) and -humulene (4.0%) were the major constituents. Thirty-two compounds, comprising 98.0%, were identified in C. zeylanicus oil, of which -caryophyllene (21.6%),-pinene (20.4%) and E--ocimene (11.8%) were the major components. The antibacterial and antifungal activities of the oils were tested against a panel of five bacterial and two fungal strains. The oils showed moderate activity against all the tested microbial strains. The minimum inhibitory concentrations of the oils were also determined.

Analysis of the Essential Oil of the Rhizome ofCyperus giganteusVahl. (Cyperaceae) Cultivated in North of Brazil

Abstract: The volatiles of Cyperus giganteus (Cyperaceae), cultivated in the state of Pará were obtained by hydrodistillation and analyzed by GC and GC/MS. The major components identified in the rhizome oil of C. giganteus were cyperotundone (25.9%) and cyperene (10.4%).
