摘要： 通过对15种热带乔灌木不同月份(2009年3月至2010年2月)单宁含量的测定,以期明确部分木本饲用植物单宁含量及其动态变化趋势。结果表明:15种热带乔灌木单宁平均含量由低到高顺序如下:对叶榕(Semen cuscuta L.f.)(0.39%)<刺桐(Erythrina variegata Linn.)(0.77%)<克拉豆(Cratylia argentea(Desv.)Kuntze)(0.78%)<假木豆(Dendrolobium triangulare(Retz.)Schindl.)(1.16%)<木豆(Cajanus cajan(Linn.)Huth)(1.29%)<双荚决明(Senna bicapsularis(Linn.)Roxb.)(1.38%)<破布叶(Microcos paniculata Linn.)(1.56%)<圆叶舞草(Codariocalyx gyroides(Roxb.ex Link)Hassk.)(1.57%)<大果榕(Ficus auriculata Lour.)(1.62%)<长穗决明(Senna didymobotrya(Fresen.)H.S.Irwin et Barneby)(1.82%)<大叶千斤拔(Flemingia macrophylla(Willd.)Prain)(1.91%)<黄牛木(Cratoxylum cochinchinense(Lour.)Blume)(2.14%)<银合欢(Leucaena leucocephala(Lam.)de Wit)(2.34%)<金合欢(Acacia farnesiana(Linn.)Willd.)(2.67%)<白饭树(Flueggea virosa(Roxb.ex Willd.)Voigt)(2.80%);15种热带乔灌木单宁含量差异较大且含量随月份变化明显。不同植物种类、生长时期、生长环境等可能是导致单宁含量差异的原因。

Abstract: Tannin contents of 15 tropical trees and shrubs were observed from March 2009 to Feb.2010.Tannin levels of forage plants were ranked as: Semen cuscuta L.f. (0.39%),Erythrina variegata Linn. (0.77%);Cratylia argentea (Desv.) Kuntze (0.78%);Dendrolobium triangulare (Retz.) Schindl. (1.16%);Cajanus cajan (Linn.) Huth (1.29%);Senna bicapsularis (Linn.) Roxb. (1.38%);Microcos paniculata Linn. (1.56%);Codariocalyx gyroides (Roxb.ex Link) Hassk. (1.57%);Ficus auriculata Lour. (1.62%);Senna didymobotrya (Fresen.) H.S.Irwin et Barneby (1.82%);Flemingia macrophylla (Willd.) Prain (1.91%);Cratoxylum cochinchinense (Lour.) Blume (2.14%);Leucaena leucocephala (Lam.) de Wit (2.34%);Acacia farnesiana (Linn.) Willd. (2.67%);Flueggea virosa (Roxb.ex Willd.) Voigt (2.80%).There were significant monthly dynamic of tannin contents in all tested tropical trees and shrubs leaves,related to species,growing period and environment.Additionally,utilization and tannin physiology were also discussed in this paper.
