“…The weak coupling correlations between the two methyl groups CH 3 -12 and CH 3 -13 (δ 1.16; δ 1.44) are typical for geminal methyl groups. 6 This was also confirmed by the HMBC diagram. The protons of these two methyl groups show connectivity to the quaternary carbon atom C-11 (δ 82.1) and to the tertiary carbon atom C-7 (δ 52.8).…”

“…Previous investigations into the volatile constituents of other species in this genus have reported an abundance of sesquiterpenes. [4][5][6][7] The identification of these compounds from the tubers of C. esculentus from Nigeria was established for the first time. was fitted with a 25 m × 0.25 mm i.d.…”

“…[4][5][6][7] Sesquiterpenes such as cyperone, calamenene, caryophyllene, rotundene, rotundenol, humulene, selinene and cadinene have been reported to be the commonest constituents. However, no literature information is available on the volatile constituents of C. esculentus.…”

“…It has been reported that essential oil from the tubers of C. rotundus show antibacterial, antimutagenic, and antigenotoxic effects [8]. Previous phytochemical studies showed that the major chemical essential oil components of this herb were terpenoids, and mono and sesquiterpenes [9] [10].…”

Gas chromatography coupled with mass spectrometry (GC/MS), using both electron impact (EI) and chemical ionization (CI) detection modes on apolar and polar stationary phases, led to the determination of the volatile composition of the essential oil obtained from tubers of Cyperus rotundus (Cyperaceae). In this study, more than 33 compounds were identified and then compared with the results obtained in our previous work. Cyperene, alpha-cyperone, isolongifolen-5-one, rotundene, and cyperorotundene were the principal compounds comprising 62% of the oil. An in vitro cytotoxicity assay with MTT indicated that this oil was very effective against L1210 leukaemia cells line. This result correlates with significantly increased apoptotic DNA fragmentation. The oxidative effects of the essential oil were evaluated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH), xanthine/xanthine oxidase assays, and the scavenging of superoxide radical assay generated by photo-reduction of riboflavin. The antimutagenic activity of essential oil has been examined by following the inhibition of H(2)O(2) UV photolysis which induced strand-break formation in pBS plasmid DNA scission assay. Based on all these results, it is concluded that C. rotundus essential-oil composition established by GC/MS analysis, in EI- and CI-MS modes, presents a variety of a chemical composition we were not able to detect with only GC/MS analysis in our previous work. This essential oil exhibited antioxidant, cytotoxic, and apoptotic properties.
