-"The volatile constituents were isolated from the root of S costus cultivated in Chamoli district of Uttrarakhand by hydro distillation and were analyzed by gas chromatography-mass spectroscopy (GC-MS)... A total 35 aroma compounds representing about 92.81% of the total composition were identified. Aldehyde like (7Z,10Z,13Z)-7,10,13-hexadecaterienal (25.5%) was found as a major compound including other ketones like dehydrocostus lactone (16.7%), alcohols like elemol (5.84%), γ-costol (1.80%), vulgarol B (3.14%), valerenol (4.20%), and terpinen-4-ol (1.60%), etc. Esters and acids were found to be completely absent..." \\
