以黔东南产仙鹤草为试材,研究测定了仙鹤草多糖含量和抗氧化能力,以期为仙鹤草开发利用提供依据。结果表明:黔东南产仙鹤草多糖的含量较高(以葡聚糖计),为4.98mg/g,对DPPH自由基的清除率在52μg/mL时达64.1%,312μg/mL时高达93.9%。对DMPD自由基的清除率在52μg/mL时达53.1%,312μg/mL时高达80%。黔东南州产仙鹤草多糖含量较高和抗氧化能力较强,开发价值大。 In order to provide the basis for the development and utilization of Agrimonia pygnus, the polysaccharide content and antioxidative ability of Agrimonia pilosa L. were measured using Agrimonia sp. The results showed that the polysaccharide content of Agrimonia pygmycti in Southeastern China was higher (according to dextran) and was 4.98 mg/g. The DPPH radical scavenging rate was 64.1% at 52 μg/mL and 93.9% at 312 μg/mL. . The clearance rate of DMPD free radicals was 53.1% at 52 μg/mL and 80% at 312 μg/mL. The polysaccharide content of Agrimonia pygmyodeskii in Southeast Guizhou is high and its antioxidant capacity is strong, and its development value is high.
