Chemical composition and antioxidant activity of the hexane fraction from leaf extracts of Odontonema strictum

AUTHOR(S): Lokadi Pierre Luhata, Moena Hirao, Natsuki Mori and Toyonobu Usuki
ABSTRACT:Plants of the genus Odontonema are used in traditional medicine to treat open wounds, inflammation, hypertension, and to induce labor. The objective of this study was to determine the chemical composition of the hexane fraction from O. strictum aerial parts and evaluate its ability to scavenge DPPH radicals under laboratory conditions. The chemical composition of the hexane fraction was determined by GC-MS. Essential oils exhibiting >95% search similarity was identified. Analysis of GC-MS spectra revealed the presence of neophytadiene, hexadecanoic acid, hexahydrofarnesyl acetone, phytol, tetratetracontane, squalene, methyl stearate or octadecanoic acid, 2-methyloctacosane, and tritetracontane. The hexane fraction demonstrated moderate antioxidant activity (IC50 = 1 mg/mL). This is the first report describing the chemical composition and antioxidant activity of extracts of fatty leaves of O. strictum. The results support the use of this tropical plant in folk medicine to heal open wounds and as an anti-inflammatory agent.
