测定了12种植物蜂花粉中总酚、苯丙素类、黄酮醇类和花色苷等酚类成分及其抗氧化能力。以总抗氧化活性、自由基清除活性和羟自由基清除活性为指标测定其抗氧化能力。花粉酚类物质含量的变异性很大。总抗氧化活性差异很大（0.8-86.4%的脂质过氧化抑制），然而，在大多数检查的花粉中，自由基清除活性与苯丙素类化合物水平相一致，（DPPH中和的8.6-91.5%）和羟基自由基清除活性（10.5-98%的脱氧核糖降解抑制），并与酚类化合物的含量无关。在所调查的大多数植物中，蜂花粉的抗氧化能力都很强。(c)2005爱思唯尔有限公司保留所有权利。
Phenolic constituents (total phenols, phenylpropanoids, flavonols and anthocyanins) and antioxidant ability were determined in bee pollen of 12 plant species. Antioxidant ability was measured as total antioxidant activity, radical-scavenging activity and activity against free hydroxyl radical. Great variability of phenolic contents was observed in the pollen of investigated species. Total antioxidant activity differed considerably (0.8-86.4% inhibition of lipid peroxidation), however, in most of the examined pollens, it was high and corresponded with the phenylpropanoid level.Great differences in the radical-scavenging activity (8.6-91.5% of DPPH neutralization) and in the hydroxyl radical-scavenging activity (10.5-98% inhibition of deoxyribose degradation) were observed and were not correlated with the content of phenolic compounds. In most of the investigated plant species, antioxidative capacity of bee pollen was very high. (c) 2005 Elsevier Ltd. All rights reserved.
