Comparative Aroma Profile of Wild and Cultivated Chenopodium ambrosioides L. from Uttarakhand

Abstract In the present investigation the essential oils of Chenopodium ambrosioides L. aerial parts obtained from wild sources and cultivated field were analyzed by GC and GC-MS. The essential oil yields, obtained by hydro-distillation were 0.28 % in wild and 0.16 % in cultivated Chenopodium. The GC and GCMS analysis of the essential oils led to the identification of 18 components representing 90 % of the oils. The major component in wild sample was α-terpinene (44.68 %) followed by p-cymene (21.28 %) and ascaridole (17.89 %), whereas in cultivated sample ascaridole (44.96 %) was found in abundance. p-cymene (27.14 %) and α-terpinene (8.27 %) were other two major components in cultivated Chenopodium. Wild sample detected major fraction of monoterpene hydrocarbons, whereas as cultivated oil dominated by oxygenated monoterpenes. Study concluded that oil of C. ambrosioides originated from Uttarakhand region can be use pharmaceutical preparations along with combination of other desired molecules for industrial applications.
