FT-IR coupled secondary metabolites profiling and biological activities of <i>Neolamarckia cadamba</i> leaves

<i>Neolamarckia cadamba</i> is a pharmacologically significant tropical tree, exploited for various biological studies due to its rich secondary metabolites. In the present investigation, comparison of pharmacological and five different extracts leaves have been carried out. This first report phytochemical extracts, coupled with FT-IR spectroscopy. Methanol extract (NCLE-D) was found be in also showed higher phenolic (279.023 GAE/g extract) flavonoid (1067.48 QE/g contents. Ethyl acetate (NCLE-C) NCLE-D free radical scavenging activity IC<sub>50</sub> 15.17 µg/mL 16.12 respectively compared ascorbic acid (positive control) 5.22 µg/mL. NCLE-C exhibited antibacterial as well. These results suggest that capable producing bioactive compounds especially from leaves; hence, could valuable source new drugs treating diseases.
