different parts of cymbopogon flexuosus var. krishna, namely leaf lamina, leaf sheath, inflorescence stem, spikelet, root, rhizome and root + rhizome yielded 1.7%, 1.3%, 0.25%, 0.6%, 0.05%, 0.3% and 0.2% essential oils, respectively on a fresh weight basis. gas chromatography-flame ionization detector (gc-fid) and gc-mass spectrometry (gc-ms) analyses showed seventy-three components constituting 93.5-99.7% of these oils. leaf lamina oil was richer in isopulegol (1.9%), neral (34.8%) and citral (83.0%); leaf sheath oil in -caryophyllene (1.5%) and caryophylleneoxide (1.9%); inflorescence stem oil in 6-methyl heptenone (3.1%), terpinolene (1.1%) and geranial (48.9%); spikelet oil in sabinene (1.5%), -terpinene (1.3%), geraniol (12.1%), geranyl acetate (8.3%) and (e)-cadina-1(2),4-diene (1.9%); root oil in terpinen-4-ol (9.0%), -elemene (6.6%), -longipinene (2.7%), -elemene (2.4%), -cadinene (2.2%) and bulnesol (10.8%); rhizome oil in elemol (42.3%), eudesm-3-en-7-ol (29.5%) and -bisabolone oxide a (9.1%); and root + rhizome oil in eudesm-11-en-4-ol (9.6%) and epi--eudesmol (6.1%). currently, leaf lamina oil is commercially produced. this investigation has revealed that leaf sheaths (76.2%) and inflorescence stems (80.5%) yielded citral-rich oils. elemol, which finds application in fragrances with potential use in botanical pesticides, can be isolated from rhizome oil.
