| 摘 要： | 通过对云南省几种主要豆科饲用灌木不同生育期酚类化合物含量的分析研究，结果表明，单宁的含量变化范围从银合欢的枯黄期（４２．９ｇ／ｋｇ）到假大青蓝的开花期（１２３．６ｇ／ｋｇ）之间；简单酚的含量变化范围从银合欢的营养期（１１．６ｇ／ｋｇ）到结荚期（５８．７ｇ／ｋｇ）之间；总酚的含量在各生育期的变化范围依次为１０９．１～１７３．３，１０４．１～１６９．２，１０３．７～１５３．０和８６．６～１５５．６ｇ／ｋｇ。４种酚类化合物含量都较高的灌木有假大青蓝，含量均较低的有多花木蓝和假木豆。４种酚类化合物的含量总体表现为总酚＞单宁＞缩合单宁＞简单酚。缩合单宁与总酚和单宁之间呈极显著正相关（犘＜０．０１），与简单酚之间呈不显著的负相关（犘＞０．０５）。体外干物质消化率（ＩＶＤＭＤ）在同一生育期不同灌木间差异显著（犘＜０．０５），体外有机物消化率（ＩＶＯＭＤ）在同一生育期不同灌木间差异显著（犘＜０．０５）。体外消化率和体内消化率与总酚、单宁和缩合单宁呈极显著负相关（犘＜０．０１），且相关系数绝对值大于０．７。

| Abstract: | Several legume shrubs in Yunnan province were analyzed to understand the dynamic changes in phenol content during different growth stages.The results showed that TET content(42.9 g/kg)changed from the wilting stage of Leucaena glauca to the flowering stage of Indigofera galegoides DC(123.6 g/kg);SPH content changed from the nutritional stage of L.glauca(11.6 g/kg) to the seed set stage(58.7 g/kg).The TEPH content of each growth stage was followed by a change in the ranges of 109.1-173.3 g/kg,104.1-169.2 g/k... |
