Biochemical Studies and Trace Elements Profiles of Cymbopogon jwarancusa

Karamat Mahmud, Rehana Naseer, M. Shahid and Samia Rashid
This research paper reports the biochemical analysis and trace element analysis of Cymbopogon jwarancusa. Biochemical studies indicated that moisture contents, 67.02%; ash contents, 9.52%; carbohydrates, 1.8%; reducing sugar, 1.07%; non reducing sugar, 0.80%; nitrogen, 0.67%; crude proteins, 5.02%; crude fiber, 9.50%. The seed of Cymbopogon jwarancusa was used to extract oil, (yield of oil was 2%). Extracted oil indicated acid value, 7.32%; iodine value, 1.6%; saponification value, 155.25%; peroxide value, 18.2%; refractive index, 1.432 and pH of extracted oil was 4.45. Trace element analysis showed sodium (Na+) 0.60%, potassium (K+) 0.20%, lithium (Li+) below detection limit, nickel (Ni++) 0.21%, lead (Pb++) 0.34%, cadmium (Cd++) 0.12%, zinc (Zn++) 0.98%, copper (Cu++) 0.10%, manganese (Mn++) 1.25%, iron (Fe++) 1.37% and cobalt (Co++) 0.31%, were determined.
