摘要
根据试样对二苯代苦味肼基自由基(DPPH·)的清除作用,评价了香叶天竺葵茎和叶精油及其单体,以及蒸馏后的残渣和废水的抗自由基活性。所试样品中几乎都有一定的抗氧化作用,以中午采集的叶片提取物的DPPH·清除率最高,达 99 .70%。废水和残渣的清除率分别达 97. 56%和 90 .24%。提示天然香料工业所弃的废水和残渣可提取到具有较强的抗自由基活性的物质,为种植香叶天竺葵综合利用提供了可能。
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.
