Functional group analysis of Cleome viscosa L. and C. burmanni W. & A. (Cleomaceae) extracts by FT-IR

The present study attempts to establish the FT-IR profile and identify the functional components of the methanol extracts of two species of Cleome, C. viscosa and C. burmanni. Similar absorption peaks were exhibited by the two species at different transmission percentages. Also, most of the functional groups observed as per their peaks are similar in the two species with a difference only in their wave numbers. An effort was made to link the observed bands to the probable components in the samples. The two species could be distinguished based on the presence of certain marker compounds. Aromatic amines and alkynes were observed only in C. viscosa while C. burmanni contained phenols. The possible bioactive properties of the detected compounds are also discussed.
