摘要 测定了5种(6份种质)千斤拔属(Flemingia Roxburgh ex WT.Aiton)饲用植物茎、叶在不同月份(2010年6月至2011年5月)的单宁含量,揭示其动态变化趋势。结果表明:6份千斤拔叶片单宁平均含量由低到高依次为大叶千斤拔Ⅰ(种质源自海南,1.82%)<腺毛千斤拔(1.93%)<大叶千斤拔Ⅱ(种质源自越南,2.17%)<海南千斤拔(2.28%)<球穗千斤拔(2.55%)<宽叶千斤拔(2.70%);茎中单宁平均含量由低到高顺序为大叶千斤拔Ⅰ(种质源自海南,1.05%)<球穗千斤拔(1.08%)<腺毛千斤拔(1.43%)大叶千斤拔Ⅱ(种质源自越南,1.56%)<宽叶千斤拔(1.60%)<海南千斤拔(1.64%)。6份千斤拔叶片的单宁含量均高于相应的茎含量,并随月份的推移而变化。这表明千斤拔单宁的含量受种类、器官及生长时期的影响。 Tannins contents of 5 species of genus Flemingia Roxburgh ex WT. Aiton were determined from June 2010 to May 2011. Tannins levels in the leaves of Flemingia were ranked as: F. macrophylla I (1.82%), F. lineata (1.93%), F. macrophylla II(2.17%), F. latifolia var. hainanensis(2.28%), F. strobilifera (2.55%), F. latifolia (2.70%). Tannins levels in the stem of Flemingia were ranked as: F. macrophyUa I (1.05%), F. strobilifera (1.08%), F. lineata(1.43%), F. macrophylla II (1.56%), F. latifolia(1.60%), F. latifolia var. ha/nanens/s(1.64%). Tannins content in the leaves was higher than that in the stems, and related to species, organs,growing period and environment.
