Abstract:

Rabdosia serra (Maxim.) Hara leaves were extracted with 60% ethanol, and were further separated by solvent extraction into four fractions, i.e., petroleum ether fraction, ethyl acetate fraction, n-butanol fraction and water fraction. Components in petroleum ether and ethyl acetate fractions were analyzed by using gas chromatography-mass spectrometry. Totally 15 compounds were identified, and most of these compounds are higher fatty acids, especially n-hexadecanoic acid and 9,12,15-octadecatrienoic acid. Trace 2,2'-methylene bis(6-tert-butyl-4-methylphenol), a strong antioxidant, was found in the petroleum ether fraction.

Key words: gas chromatography-mass spectrometry (GC-MS), Rabdosia serra (Maxim.) Hara leaves, extract, weak polar components, antioxidant
