[Study on antioxidant activity of essential oils and its monomer from Pelargonium graveolens].
The antioxidant effects of essential oil and monomer as well as residue and waste water after distillation from buds, stems and leaves of Pelargonium graveolens were studied by the method of 1,1-diphenyl-2-picryl hydrazyl free redical (DPPH*). It showed that each sample in the test had the antioxidant effect. The extraction of the leaf collected in noon had the strongest antioxidant effect, the residue and waste water had also strong antioxidant effect. It shows that some antioxidant chemical abounds in the residue of natural essential industry, and it also shows feasibility of integrated use of Pelargonium graveolens.
