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.
