The main objectives of the present study were to evaluate the preliminary phytochemical compounds and FTIR analysis of Corbichonia decumbens. The FTIR method was performed on a spectrophotometer system, which was used to detect the characteristic peak values and their functional groups. The results showed in preliminary phytochemical analysis are Alkaloids, Flavonoids, Saponins, Glycosides, Steroids were observed in hexane and ethanol extracts. The phenol and tannins were only present in the ethanolic extract. The FTIR spectroscopic studies revealed different characteristic peak values with various functional compounds in the ethanol extracts. In FTIR analysis of C. decumbens there are 33 functional groups were identified. The FTIR analysis of C. decumbens was the first attempt based on the literature survey
