GC-MS And FT-IR Of Methanolic Extracts Of Curcuma Amada Roxb. Found In Chandel District, Manipur

Abstract

Mango ginger (Curcuma amada Roxb.) was collected from Chandel District, Manipur and phytochemicals were analysed by using GCMS and FTIR. FTIR spectroscopy of the methanol extracts indicates the presence of secondary amines (N-H), alkane (C-H), amine salt (N-H), Fluoro compound (C-F), amine (C-N), and Halo compound (C-Br). In GC-MS twelve compounds were identified: 4-dimethyl (pentafluorophenyl) silyloxypentadecane (100%), 4H-1-benzopyran-4-one, 5-hydroxy-7-methoxy-2-phenyl- (28.806%), Endo-borneol (3.38%), Linalool (3.03%), D-Limonene (2.74%), 1,2,3,4-dodecanetetrol, [2r-(2r*,3s*,4s*)]- (1.27%), and the minor compounds are Cis-2-methyl-4-n-pentylthiane, s, s-dioxide (0.42%), z,z-6,28-heptatriactontadien-2-one (0.43%), 3-methyl-2-(2-oxopropyl)furan (0.43%), 1h-3a,7-methanoazulene, octahydro-1,4,9,9-tetramethyl (0.74%), 3-methyl-2-(2-oxopropyl)furan (0.52%), 3-methyl-2-(2-oxopropyl)furan (0.74%).  The main chemical constituents were 4-dimethyl (pentafluorophenyl) silyloxypentadecane (Retention time: 38.097,  peak area: 28.806, Molecular formula: C₂₃H₃₇OF₅Si) and 4H-1-benzopyran-4-one, 5-hydroxy-7-methoxy-2-phenyl- (Retention time: 37.742, peak area: 24.136, Molecular formula: C₁₆H₁₂O₄).
