Received on: ; Revised on: ; Accepted on ABSTRACT In the current study, the mono and sesquiterpenoid composition in the leaves and stem of Artemisia amygdalina Decne is tracked by probing the contents of individual mono and sesequiterpenoids in the leaf and stem essential oils obtained by hydrodistillation using a combination of capillary GC-FID and GC-MS analytical techniques.
The analysis led to the identification of 25 components in the leaf and 32 components in the stem essential oils. The leaf essential oil is dominated by monoterpene hydrocarbons The principal components were sabinene The stem essential oil is dominated by monoterpene hydrocarbons This genus belongs 2. Extraction of the Essential Oils to a useful group of medicinal and aromatic plants comprising of about species The shade dried leaves and stem of the plant were finely chopped and most of which are distributed in North America, Europe, Asia and North Africa [1,2].
The oil obtained was dried over anhydrous sodium sulphate and Western Himalayan region [2]. Artemisia species are popular from the chemical, stored at 4 0C in a sealed vial until analysis. The genus Artemisia is known to contain many Gas chromatography was carried out on Perkin Elmer auto system XL Gas bioactive compounds such as artemisinin which possesses antimalarial and cytotoxic Chromatograph series equipped with flame ionization detector FID activity against tumor cells [ 4 ], arglabin another bioactive molecule is used and head space analyzer using a fused silica capillary RTX -5 Column for treating certain types of cancer in the former USSR [5].
It is a tall, stout stemmed leafy aromatic perennial herb with simple serrate leaves which are hoary tomentose beneath and glabrous green above, 2. In the traditional system of GC- MS analysis was carried on a Varian Gas Chromatograph series medicine, the plant is used by locals for the treatment of cough, cold, worms fitted with a VF 5 ms fused silica capillary column 60m x 0.
It is also used as vermifuge [6]. Despite being a very important film thickness 0. The plant as carrier gas at 1. The relative percentages of the individual components were calculated based on GC peak area FID response without using correction factors.
Plant Material The plant material of Artemisia amygdalina was collected from the Gurez 3. A voucher specimen voucher number, amygdalina are shown in table-1, in order of their elution from RTX-5 KASH of the plant material was deposited in the Kashmir column.
The oil yields calculated on dry weight basis were 0.

In conclusion, the present report of the chemical profile of the essential oil of Artemisia amygdalina which is the first ever report provides a further in- 95 depth information about the chemo diversity in the chemical composition of the essential oil of the genus Artemisia.
