Opis:
Aims of this study were to investigation the presence of phytochemical compounds in the methanolic extract of Cressa cretica L. leaves by using GC-MS method and report the functional groups by using FT-IR spectroscopy. The identification of phytochemical compounds based on the peak area, retention time, molecular weight, molecular formula, MS fragment ions. Thirty four phytochemical compounds were identification in the methanolic extract of Cressa cretica leaves. The GC-MS analysis provide the existence of 5-Methyl-6-phenyltetrahydro-1,3-oxazine-2-thione, Lactose, 3-Deoxy-L-ribose-2,5-dibenzoate, Sarreroside, Pterin-6-carboxylic acid, Octadecadiynoic acid, methyl ester, d-Mannose, Dodecanoic acid, 3-hydroxy-, Geranyl isovalerate, Tetradecanoic acid , 6-epi-shyobunol, Paromomycin, Cis-9-Hexadecenoic acid, and others. The FT-IR analysis revealed the presence of Alkenes, aliphatic amines, nitro compounds, alkanes. These are chemical compounds are may be useful for various herbal formulation as antifungal, antibacterial, anti- inflammatory, anti-oxidant and others.

Opis:
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.
