PHYTOCHEMICAL SCREENING AND ESSENTIAL OIL ANALYSIS OF ONE OF THE PERSIAN SEDGES; CYPERUS ROTUNDUS L.Abstract
Phytochemical investigations of tuber extracts and evaluation of the hydro-distilled essential oil, obtained from Cyperus rotundus L. (Cyperaceae Family) growing wild in Isfahan Province (Iran) were studied. Phytochemical surveys revealed the presence of flavonoids, tannins, alkaloids and essential oils. Chemical composition of dried tubers essential oil was also analyzed by GC/MS. Sixty natural compounds consisting 95.8% of the total components were identified from the essential oil obtained with a yield of 0.2% (w/w). Sesquiterpene compounds have been found to occur in largest amount in the oil. Among the oil constituents, cyperene (16.9%), caryophyllene oxide (8.9%), α-longipinane (8.4%) and β-selinene (6.6%) were the major components.
