对苯酚-硫酸比色法测定毛竹竹叶中的多糖含量进行了研究。结果表明此法灵敏度高，重复性好，多糖最佳检测波长为490nm，在浓度20--100μg／mL范围内线性相关系数R^2=0．9993，重现性标准差为0.0055，回收率99.22％。

The content of total polysaccharides in Phyllostachys pubescens leaves by phenol-vitriolic colorimetry were studied. Results showed that this method was credible and reproducible and the linear concentration range was within 20--100 μg/mL （R2=0.9993） at the best detection wavelength of 490nm, recurrence standard deviation was 0.00...
