Chemical constituents of the volatile oil ofcyperus esculentus L. from Nigeria

Volatile oils obtained by hydrodistillation of the tubers of two varieties (brown and black) of Cyperus esculentus L. (Cyperaceae) were analyzed by GC and GC-MS. Nine and 11 compounds, representing 91.7–99.7% of the total volatile oils were identified, respectively, from the brown and black varieties. The most representative compounds were α-pinene (70.5–75.5%) and α-thujene (5.2–10.2%).
