UV-VISIBLE SPECTROSCOPIC AND FTIR ANALYSIS OF SARCOSTEMMA BREVISTIGMA, WIGHT. AND ARN

Abstract

Objective:  The present study was carried out to characterize the bioactive constituents present in aerial parts of ethanolic extract of Sarcostemma brevistigma using UV-VIS and FTIR.Methods:  FTIR spectroscopy is an established time‐saving method to characterize and identify functional groups.Results:  The UV-VIS profile showed different peaks ranging from 200‐1044 nm with different absorption respectively. UV-VIS profile showed the peaks at 254.00 and 680.00 nm for flavonoid. FTIR spectra showed the peak at 3418.85 cm-1 for N-H group. FTIR analysis and UV-VIS analysis showed the presence of flavonoids and a phenolic compound. The FTIR spectra had amply evidenced the occurrence of OH group together with the Terpenoids, and Phenol. The FT-IR spectrum showed the presence of an amine (N-H), alkyl (C-H), nitrile (C≡N), halo formyl (C=O), alkenyl (C=C), hydroxyl (O-H), haloalkane (C-F), nitrates and carbonate compounds.Conclusion:  The results confirm the fact that this plant posse’s important bioactive constituent, so further scientific investigation is needed.
