Evaluation of phytoconstituents of Caralluma nilagiriana by FTIR and UV-VIS spectroscopic analysis

Abstract

Spectroscopic techniques can advantageously be employed for qualitative and quantitative analysis of plant extracts. In the present work we deal with the nature of visible absorption spectra of ethanolic leaves’ extract of Caralluma nilagiriana medicinal plant. Caralluma nilagiriana is a plant known to be rich in phytoconstituents that are regarded as compounds possessing beneficial biological activities and, in view of this phenomena, an attempt at identifying such phytoconstituents present in C. nilagiriana was undertaken. FTIR analysis and UV-VIS analysis showed the presence of phenolic compound and flavonoids; while the peaks at 227.6nm, 401.6nm and 664.6nm of the UV-VIS profile corresponded to those of the Flavonoid, Terpenoids, and Chlorophylls’ respectively, the ones of the FTIR spectra had amply evidenced the occurrence of OH group together with the Terpeniols, Phenol& Alcohol, Carboxylic Acids, Nitro Groups, Esters and Ethers.
