Chemometric Resolution for Baseline Identification of Amomum subulatum Roxb. Essential Oils through FT-IR Spectroscopy Technique
Abstract: Essential oil of Amomum subulatum is the complex mixture of various alkyl, alkanes, sulfonates, amines, alcohols, sulfoxides, trans RCH≡CHR and aromatic bending compounds. The FT-IR analysis of aromatic bending occurs on 845 cm-1 with para C-H bend. A strong absorption band between 900 cm-1 - 675 cm-1 indicated the presence of aromatic C=C. The alcoholic stretching detected on 1080 cm-1 and 1169 cm-1 with C-O stretching molecular motion in large cardamom. In our investigation, the frequency of 2943 cm-1 and 2934 cm-1 the C-H stretching occurred in alkyl group. The wave numbers of bands 2966 (C=CH2), 1358 (S=O Stretch), 1215 (C-N Stretch), 1053 (S=O Stretch) and 984 (C-H Bending) the functional group specify vinyl, sulfonates, amines, sulfoxides and trans RCH-CHR, respectively.
