Inter-specific and inter-cultivar variations in the essential oil profiles of lemongrass

The essential oil profiles of five Cymbopogon flexuosus cultivars (OD-19, Pragati, Cauvery, SHK-7 and GRL-1), one C. pendulus cultivar (Praman) and one hybrid C. khasianus X C. pendulus cultivar (CKP-25) were examined by capillary GC. Cultivar GRL-1 could be distinguished from other cultivars by the...

Description
Summary:The essential oil profiles of five Cymbopogon flexuosus cultivars (OD-19, Pragati, Cauvery, SHK-7 and GRL-1), one C. pendulus cultivar (Praman) and one hybrid C. khasianus X C. pendulus cultivar (CKP-25) were examined by capillary GC. Cultivar GRL-1 could be distinguished from other cultivars by the presence of high amounts of geraniol (80.21%) and relatively higher concentrations of myrcene (3.97%), (E)-beta-ocimene (1.37%) and geranyl acetate (4.60%). All of the other six cultivars contained neral (33.31-36.06%) and geranial (45.07-54.52%) as the major constituents in their oils, though they differed in their composition of minor compounds. Cultivars belonging to C. flexuosus possessed higher levels of total citral (neral + geranial) (85.42-89.69%) than C. pendulus (84.89%) or C. khasianus X C. pendulus (80.00%) cultivars. The hybrid lemongrass CKP-25 differed from other citral-rich varieties with respect to a number of minor components
