摘要:
采用层次-向量法, 从生态因子、有效成分含量、抗氧化活性3个层次, 分析了层次间关系, 研究了生态因子对普通鹿蹄草(Pyrola decorata)品质的影响, 揭示影响其有效成分含量的生态主导因子。结果表明: 不同地区普通鹿蹄草的4种有效成分含量及抗氧化活性差异显著。抗氧化活性(DPPHIC50值)与单宁、金丝桃苷、槲皮素含量呈负相关关系, 其相关系数分别为: -0.829、-0.378和-0.749, 与总黄酮含量表现为正相关(p = 0.260)。单宁含量和槲皮素含量是影响抗氧化活性的重要指标, 其含量增加时DPPHIC50值下降, 抗氧化活性增强。年平均气温、一月份平均气温、年积温、年极高气温、无霜期、土壤全氮、速效氮、速效磷和有机质是影响有效成分含量的主要因子, 其中土壤因子对有效成分含量的影响更显著。土壤因子对单宁和槲皮素含量的影响最大, 对金丝桃苷含量影响最小; 气候因子对4种有效成分含量影响较弱且对各成分的影响程度基本相同。研究结果表明, 选择合适的生境, 尤其是土壤因子可有效地提高普通鹿蹄草的品质。
