摘　　要：采用分光光度法对四川王朗自然保护区缺苞箭竹的总酚含量进行了分析,结果表明:在采集到的不同器官中均有酚类物质分布,总酚含量最高的为叶龄超过1 a的老叶(2.05%),笋中的总酚含量最低(0.20%)。海拔高度和日照强度在一定程度上影响其含量变化,在海拔高和光照强的条件下,幼嫩器官中的总酚含量有明显增加的趋势。研究分析了缺苞箭竹各器官总酚含量的变化规律,及其与环境因子和大熊猫采食量之间的关系。This paper studied the second metabolism changes under the natural forest condition.Concentrations of total phenolics were measured in Fargesia denudate by a colorimetric method.The results showed that phenolic compounds in bamboo were present throughout the collected organs with the highest concentration in old leaves（2.05%） and the lowest content（0.20%） in shoots.Sunshine and air temperature influence the concentrations of total phenolics.With the increment in altitude and solar radiation,there is an obvious increase of total phenolics in young bamboo organs.By a data analysis,it has revealed that close relationship existed among the variation of total phenolics in different organs of Fargesia denudate,the environmental factors and the ingestive volume of the Giant panda（Ailuropoda melanoleuca）.
