DOI:10.5958/2230-732X.2014.01403.X

Abstract:

Cymbopogon citratus is widely used in nutraceutical industries due to its strong lemony odor for its high content of the aldehyde citral and small quantities of geraniol, geranyl acetate and monoterpene olefins. Present studies were conducted to estimate the essential oil at different drying condition viz., sun-drying, shade-drying and oven-drying and analyzed for physicochemical properties (acid value, saponification value and iodine value). The maximum essential oil (3.05%) recovered in oven drying method while, the minimum saponification value (142.59 mgKOH/g) was recorded in sun drying method, however, the minimum acid value (4.14 mgKOH/g) and iodine value (114.31gI 2/100g) were recorded in shade drying method. The essential oils were analyzed by GC/MS instruments and identified eleven different components. Among the components identified, geranial (citral-a), neral (citral-b), caryophellene and limonene were found major components in the lemongrass essential oils.
