ABSTRACT
Phytochemicals and antioxidant potentials of chloroform extract of leaves of Cyathea latebrosa have been investigated. The metabolites detected are Carbohydrates, starch, glycosides, saponins, alkaloids, tannins, flavonoids, sterols, terpenes, and polyuronides. Quantitative Phytochemical analysis gave alkaloid (0.08×102 ±0.02), saponins (0.16×102 ±0.02), tannin (0.11×102 ±0.01), flavonoid (0.16×102 ±0.01), and phenol (0.18×102 ±0.01). FT-IR (KBr) cm-1 analysis showed -NH-(3433.41 weak), -OH- (3851.01 sharp), -C-F (1408.8 strong) –SO-(1101.39) and Ar (1646.3 weak), GC/MS characterization revealed the extract contained [2-Aziridinylethyl]amine (70.7%), Benzeneethamine, 3-fluoro-β,5-dihydroxy-N-methyl (14.0%), N-Methyltaurine (10.7%) and (R)-(-)-2-Amino-1-propanol (3.15%). The presence of these compounds exposed the leaves as a potential remedy for alleviated cold, cancer, malaria and to regulate immune functions. At 400 µg/ml concentration the extract and ascorbic acid produced 54.34% and 96.02% antioxidant activity respectively. The FRAP values were significantly (p < 0.05) low than the value of ascorbic acid (2µ M). The plant extracts showed low antioxidant potential even on higher concentrations when compared to reference standard ascorbic acid.
