Comparative fingerprint and extraction yield of Prosopis cineraria (Lin.) Druce. Leaves with phenolic compounds (Gallic acid) & flavonoids (Rutin)
The main objective of this study is to analyse the extraction yield of Prosopis cineraria leaf with respect to phenolic compounds (Gallic acid) and flavonoids (Rutin). UV and FTIR spectroscopic methods were employed for qualitative and quantitative analysis of phenolic compounds (gallic acid) and flavonoids (rutin) in the leaf extract of Prosopis cineraria. The extraction yield of methanolic extract was found to be superior. The FTIR signals at 675-600, 1225–950, 1540-1870, and 3500–3200 cm-1, are the indicator of presence of phenol (Gallic acid) & Rutin (flavonoid). These signals were used to identify the presence of the functional groups in the extract. This study concludes that data obtained from the UV & FTIR spectroscopy is enough to fingerprint & evaluate extraction yield of Prosopis cineraria.
Key words: UV spectroscopy, FTIR spectroscopy, Methanolic extract, Rutin, Gallic acid, Prosopis cineraria.
