1. Introduction Artemisia pallens Wall. ex Dc is an aromatic herb belonging to Asteraceae family and is native of India and other tropical countries. Artemisia pallens has been used in Ayurveda for the treatment of measles, cough, cold, depression, diabetes and high blood pressure. Traditionally, the leaf powder is used as an antidiabetic, antihypertensive, and antidepressant medicine. The

therapeutic potential is due to the presence of natural bioactive compounds. The antidiabetic [1] activity of the plant has not been explored . Diabetes is a metabolic disorder characterized by the rise or fall of the blood sugar levels. The amount of people suffering from diabetes throughout the world is estimated to be 2.8% and is predicted to double every 20 years up to 2040 [2]. Oral intake of high doses of aqueous or methanolic extract of the aerial parts of the

plant was shown to decrease blood glucose level in glucose−fed hyperglycemic and alloxan- [3] treated rabbits and rats . Methyl cinnamate, ethyl cinnamate, bicyclogermacrene, 2- hydroxyisodavanone, farnesol, geranyl acetate, sesquiterpene lactones, germacranolides seems to be the important components which are present [4]. The leaves and flowers are of high value in preparing floral decorations and essential oils. The leaves are very small, bluish green with

yellow inconspicuous flowers. It is utilized in traditional Ayurvedic medicinal formulations. [5] Essential oil of Artemisia pallens is used as an antiseptic and disinfectant . Thus, the aim of the study is to investigate the antidiabetic activity of A.pallens and further chemical characterization of the extracts by phytochemical assays, the quantitative, enzymatic studies, FTIR, GC-MS and the antimicrobial analysis.
