Evaluation of antioxidant activity, phytochemical screening, FTIR characterisation and nutritional values of Passiflora Foetida methanol extract

Abstract

Hysteria, asthma, and skin illnesses with inflammation are all treated by Passiflora foetida, a wild species of the Passifloraceae family. The purpose of this work is to determine the phytochemical contents, antioxidant capabilities, and FTIR analysis of Passiflora foetida crude methanol extract. Standard laboratory methods were used to conduct the phytochemical analysis. The antioxidant activity of the methanol extract was measured using an UltraViolet-Visible Spectrophotometer at 517nm against 2, 2-diphenyl-1-picryhydroxyl (DPPH). In addition, an FTIR characterization study was performed. The sample, according to the phytochemical screening analysis, contains tannin, saponins, flavonoids, alkaloids, and phenols. At 300µg/mL concentration, the highest antioxidant activity was recorded (73.36 percent), whereas, at 1000µg/mL concentration, the lowest activity (60.31 percent) was obtained. FTIR spectrum bands of 2852–2922 cm-1 -CH- group, 1507 – 1715 cm-1 band of C-C aromatic group, 1173 – 1362cm-1 band of C-O aromatic and ester groups are notable in the spectrum. The results of this study revealed that Passiflora foetida may be a promising plant to be exploited in drug discovery.
