Abstract: Alpinia manii Roxb. is endangered and endemic to Andaman and Nicobar Islands, India. The present work aimed at phytochemical profiling of fresh rhizome by GC- MS method to find medicinally important constituents. GC- MS by Head- space and n- hexane extract of fresh rhizome was carried out to identify major volatile constituents. A total of 37 compounds were identified by both methods. Terpinoids are the major constituents. Major compounds identified by head space method are, β- Pinene (11.78%), β -Selinene (27.45%), Limonene-6-ol pivalate (15.79%), β Bisabolene (11.36) etc. Phenol 3, 5-bis (1 1-dimethylethyl) (24.74%) and β-Selinene (11.87%) are the major compounds identified in the n- hexane extract. GC- MS analysis of A. manii revealed the presence of many valuable and variable bioactive components like β- pinene, caryophyllene, α Humulene, β- Bisabolene etc which have potential role in treating various disease condition.
