In the present study an attempt has been made to establish FT-IR profile and identify the functional components of Araucaria Heterophylla leaves. FTIR method was performed on a Thermo Scientific Spectrophotometer system which was used to detect the characteristic peak values and their functional groups. The results of Araucaria Heterophylla leaves FTIR analysis confirmed the presence of Alkanes (CH3 & =CH2) bond stretching, Primary amines(=N-H) group bending, Secondary Amide group (-N-H) 2 bands bending group, Saturated aldehyde and Anhydride (α-CH2) bending group, Alcohols & Hydroxy bending group, Alkanes bending group, Nitriles bending group & Carboxylic acid bending group which shows peaks at 2961.23 cm-1, 1649.48 cm-1, 1603.85 cm-1 , 1441.05 cm-1, 1373.71cm- 1,1043.7 cm-1, 1207.64 cm-1, 1178.55 cm-1, 1373.71 cm-1, 1245.20 cm- 1, 1178.55cm-1,877.40 cm-1, 1043.7 cm-1,835.29 cm-1, & 949.10 cm-1 respectively. The results of the present study produced the FTIR spectrum profile for the medicinally important plant Araucaria Heterophylla.

Keywords: Araucaria Heterophylla, FTIR, Functional group.
